# Supported Chains Source: https://docs.uniblock.dev/guides/getting-started/supported-chains Browse the full list of blockchains supported by Uniblock across JSON-RPC, Unified API, and direct provider integrations for over 300 networks. This page redirects to the [Chains Overview](/reference/chains/overview-chains). # Uniblock Quickstart Guide Source: https://docs.uniblock.dev/guides/getting-started/uniblock-quickstart-guide Create your first Uniblock project, generate an API key, make your first request, and integrate the Unified API into your application in minutes. New to Uniblock? Get access for free through our [dashboard](https://dashboard.uniblock.dev/). Estimated time: under 10 minutes. ## Steps 1. Create an Uniblock project 2. Make a request 3. Get your project API key 4. Set up Uniblock as your client *** ## 1. Create an Uniblock project Every Uniblock integration starts with a project. Projects hold your API keys, track your usage, and scope your analytics. Go to [dashboard.uniblock.dev](https://dashboard.uniblock.dev) and click the **Home** tab in the left sidebar. Click **Create a project** in the Get Started section on the Home page. Enter a project name and click **Create**. Your new project appears in the project list immediately. *** ## 2. Make a request Once your project is created, you can test any Unified API endpoint using the built-in API Tester, no code required. Click your project from the Home page to enter the project dashboard. In the left sidebar, go to **Endpoints → API Tester**. This opens the Uniblock Explorer in a new tab. In the Explorer, find the `/token/metadata` endpoint and expand it. This endpoint returns metadata for any ERC-20 token by chain and address. Click the **Try it out** button next to the endpoint to activate the input fields. Example parameter values are pre-filled. Click **Execute** to send the request using those values. The response body appears below with a `200` status code and the token metadata JSON. You've just made your first Uniblock API call. *** ## 3. Get your project API key The API key you saw in your project overview is what authenticates your requests and associates usage with your project. Go back to your project and open the **Overview** page. Your API key is displayed at the top; click the copy icon next to it. In the Explorer, click the **Authorize** button. Paste your API key into the `X-API-Key` field and click **Authorize**, then **Close**. With your key active, requests made through the Explorer (or your application) are tracked under your project metrics in **Endpoints → Analytics**. *** ## 4. Set up Uniblock as your client Ready to integrate Uniblock into your application? Here's a minimal Node.js example to make your first programmatic request. Create a new directory and initialize it: ```bash npm theme={null} mkdir my-uniblock-app cd my-uniblock-app npm init -y ``` ```bash yarn theme={null} mkdir my-uniblock-app cd my-uniblock-app yarn init --yes ``` Create a file named `index.js` with the following contents. Replace `YOUR_API_KEY` with your actual project API key. ```javascript index.js theme={null} const options = { method: 'GET', headers: { accept: 'application/json', 'X-API-KEY': 'YOUR_API_KEY' } }; fetch( 'https://api.uniblock.dev/uni/v1/token/balance?chainId=1&walletAddress=0x3f5ce5fbfe3e9af3971dd833d26ba9b5c936f0be', options ) .then(response => response.json()) .then(response => console.log(response)) .catch(err => console.error(err)); ``` ```bash theme={null} node index.js ``` You should see the token balance output in your console: ```json theme={null} { "balances": [ { "contractAddress": "0x0000000000095413afc295d19edeb1ad7b71c952", "balance": "100000000000000000000" }, { "contractAddress": "0x0000000035f26e72b70552b92bf7e02f67a90549", "balance": "20000000000000000000000000" } ], "cursor": "ALC_0x09a3ecafa817268f77be1283176b946c4ff2e608" } ``` Your project dashboard will also show this call in **Endpoints → Analytics**. *** ## Analytics & logs After making API calls, head to **Endpoints → Analytics** in your project to review performance and request history. * **Analytics**: shows request volume, latency, success/failure rates, and endpoint breakdowns * **See Detailed Logs** (at the bottom of the Analytics tab): shows per-request detail including provider routing, response headers, and fallback attempts See the [Analytics & Logs guide](/guides/uniblock/uniblock-analytics) for a full walkthrough. *** ### Congratulations! You've created a project, made your first request, and set up Uniblock as your API client. You're ready to start building.

Explore all available endpoints and interactive playgrounds # Hyperliquid trader leaderboard: rank a watchlist by margin Source: https://docs.uniblock.dev/guides/hyperliquid/analytics-dashboard/leaderboard Rank a watchlist of Hyperliquid traders by perps margin and live volume using batched portfolio reads and the allFills WebSocket fill stream. A leaderboard ranks traders against each other. The approach here is **watchlist-based**: you define the set of addresses to track (traders you've discovered from the fill tape, a curated list, addresses your users follow) and rank them with a single batched read per refresh, plus live volume from the stream you already have open. This scales cleanly and costs one request per cycle rather than one per trader. ## 1. Batch the portfolio reads `batchPortfolioStates` takes a `users` array and returns one result slot per address, in request order. ```javascript theme={null} const watchlist = [ "0xaaa...", "0xbbb...", // …up to 50 ]; const slots = await info({ type: "batchPortfolioStates", users: watchlist }); ``` ```json theme={null} [ { "user": "0xaaa...", "result": { "type": "portfolioState", "address": "0xaaa...", "chainId": 999, "perpetuals": { "marginSummary": { "accountValue": "125043.10", "...": "…" } }, "spot": { "balances": [] } }, "error": null }, { "user": "0xbbb...", "result": null, "error": "upstream timeout" } ] ``` **`marginSummary.accountValue` is perps margin only: it excludes vault equity**, same as on the [wallet tracker](/guides/hyperliquid/analytics-dashboard/wallet-tracker#1-read-account-state). On a leaderboard this is worse than on a single wallet page: a vault-heavy trader doesn't just display low, they can be ranked out of the board entirely, and the mis-ranking is invisible because there's nothing on screen to contradict it. Folding vault equity in requires one additional `userVaultEquities` call per watchlist address on top of the existing batched read, so one extra Info call per wallet on every refresh. At 50 wallets polled every 60 seconds that's a real, ongoing CU cost, not a one-time fix, so it's a judgment call rather than a strict correctness bug to patch silently: * if your watchlist is small and user-pinned (a personal watchlist, not a leaderboard), the scan is usually worth paying for: sum perps margin and vault equity into a combined figure (not "Total Value", since it still excludes spot balances, see the [wallet tracker](/guides/hyperliquid/analytics-dashboard/wallet-tracker#1-read-account-state)), and keep **Perps Margin** as its own column so the two numbers aren't buried into each other. * if the set is large and refreshed often (a public leaderboard), label the column **Perps Margin** rather than "Account Value", and say plainly that the ranking excludes vault equity. Don't rank on a number you haven't actually computed. Whichever you choose, don't call this column "Account Value" or "Total Value" unqualified, since either name overclaims what a perps-only (or perps-plus-vault) figure represents. Two properties of that response shape matter: **Failure is isolated per user.** A slot that failed has `result: null` and a populated `error`; the rest of the batch still succeeds. One bad address never takes down the board, but you must handle the null, or your ranking will throw on the first slot that didn't resolve. **Slots come back in request order**, with `user` echoed on each, so you can either zip by index or key by `user`. Keying by `user` is the more robust of the two. **The limit is 50 users per request.** Beyond that the request fails; it does not silently truncate. Chunk larger watchlists, and remember that each chunk is a separate billed request. ```javascript theme={null} function chunk(arr, size) { const out = []; for (let i = 0; i < arr.length; i += size) out.push(arr.slice(i, i + size)); return out; } async function fetchWatchlist(addresses) { const batches = await Promise.all( chunk(addresses, 50).map((users) => info({ type: "batchPortfolioStates", users })), ); return batches.flat().map((slot) => { const perps = slot.result?.perpetuals; return { address: slot.user, error: slot.error, accountValue: perps ? Number(perps.marginSummary.accountValue) : null, positions: (perps?.assetPositions ?? []).map((a) => a.position), unrealizedPnl: (perps?.assetPositions ?? []).reduce( (sum, a) => sum + Number(a.position.unrealizedPnl), 0, ), }; }); } ``` ## 2. Rank Perps margin is the headline metric and comes straight from the batch. Label it accordingly. As covered above, it excludes vault equity: ```javascript theme={null} const ranked = rows .filter((r) => r.accountValue !== null) .sort((a, b) => b.accountValue - a.accountValue) .map((r, i) => ({ rank: i + 1, ...r })); ``` Keep the failed rows rather than dropping them silently. Render them unranked with a "data unavailable" state. A trader vanishing from the board because of one timed-out request looks like a bug to anyone watching a specific address. ## 3. Keep it live between polls Refetching the batch every few seconds is the expensive way to make a leaderboard feel live. The cheap way is to poll slowly and recompute unrealized PnL locally against live mids in between. You already have the positions from the batch, and the price store from the [wallet tracker](/guides/hyperliquid/analytics-dashboard/wallet-tracker#4-keep-mid-prices-live). That's everything needed: ```javascript theme={null} function liveAccountValue(row) { if (row.accountValue === null) return null; // Replace each position's snapshot uPnL with one computed off the live mid. const liveUpnl = row.positions.reduce((sum, p) => { const mid = prices.get(p.coin); if (mid === undefined) return sum + Number(p.unrealizedPnl); return sum + Number(p.szi) * (mid - Number(p.entryPx)); }, 0); return row.accountValue - row.unrealizedPnl + liveUpnl; } ``` A 60-second poll with live uPnL in between gives a board that ticks continuously at 1/30th the request cost of a 2-second poll. Pause polling when the tab is hidden. A leaderboard left open in a background tab overnight is hundreds of requests nobody looked at. ```javascript theme={null} document.addEventListener("visibilitychange", () => { document.hidden ? stopPolling() : startPolling(); }); ``` ## 4. Rank by live volume Perps margin ranks *wealth* (with the vault-equity caveat above). To rank *activity*, accumulate traded notional per address from the `allFills` stream, the same subscription already powering prices and the tape. ```javascript theme={null} const volumeByAddress = new Map(); ws.on("message", (raw) => { const msg = JSON.parse(raw.toString()); if (msg.channel !== "allFills" || !Array.isArray(msg.fills)) return; for (const [address, fill] of msg.fills) { if (!fill?.coin || !fill.px) continue; const notional = Math.abs(Number(fill.px) * Number(fill.sz)); volumeByAddress.set(address, (volumeByAddress.get(address) ?? 0) + notional); } }); ``` Because `allFills` is venue-wide, this observes **every** trader, not just your watchlist, which makes it a discovery mechanism as much as a ranking one: ```javascript theme={null} // Rank the watchlist by session volume… const byVolume = watchlist .map((address) => ({ address, volume: volumeByAddress.get(address) ?? 0 })) .sort((a, b) => b.volume - a.volume); // …or surface active traders you aren't tracking yet. const candidates = [...volumeByAddress.entries()] .filter(([address]) => !watchlist.includes(address)) .sort((a, b) => b[1] - a[1]) .slice(0, 20); ``` This volume is **session-scoped**: it counts from when your stream connected, and resets on reconnect. Label it accordingly ("volume this session", not "24h volume"). If you need a persistent figure, accumulate into a datastore server-side with one long-lived connection shared across all users, rather than one per browser tab. ## 5. Assemble the surface ```javascript theme={null} async function refreshLeaderboard(watchlist) { const rows = (await fetchWatchlist(watchlist)).map((row) => ({ ...row, liveValue: liveAccountValue(row), sessionVolume: volumeByAddress.get(row.address) ?? 0, openPositions: row.positions.length, })); // Rank only the rows that have a value to rank. A slot that failed upstream is // not "last". It is unknown, and numbering it as last states something false. const ranked = rows .filter((r) => r.liveValue !== null) .sort((a, b) => b.liveValue - a.liveValue) .map((row, i) => ({ ...row, rank: i + 1 })); const unavailable = rows .filter((r) => r.liveValue === null) .map((row) => ({ ...row, rank: null })); // Unranked rows go after the ranked ones, still visible, still identifiable. return [...ranked, ...unavailable]; } startPolling(() => refreshLeaderboard(watchlist), 60_000); ``` Sensible columns: rank, address, perps margin (live) with an "excludes vault equity" label, unrealized PnL, open position count, and session volume, with the address linking through to the [wallet tracker](/guides/hyperliquid/analytics-dashboard/wallet-tracker) and [PnL](/guides/hyperliquid/analytics-dashboard/pnl) surfaces for a full history on whoever's at the top. Render a `rank: null` row with a dash and a "data unavailable" state rather than a number. A trader whose batch slot timed out on this cycle will be ranked normally on the next one, and showing them in last place in the meantime reads as a real ranking change to anyone watching that address. ## Cost summary Putting the whole dashboard together, the steady-state cost of a running instance is small and, importantly, **flat in the number of traders you display**: | Source | Cost | | ---------------------------------------- | -------------------------------------- | | `batchPortfolioStates`, 50 traders @ 60s | 50 lookups/min | | `allFills` subscription | 1/min, powers prices, tape, and volume | | `l2Book`, one coin | 0.5/min | | `webData2` + `meta` @ 60s | 2 requests/min | The single `allFills` subscription doing triple duty is the load-bearing design decision across this series. Adding traders to the watchlist grows only the batch; adding surfaces to the dashboard costs nothing extra at all. ## Where to go next * [Info API overview](/guides/hyperliquid/info-api/overview) lists every supported Info type. * [Rate limits, caching & polling](/guides/hyperliquid/info-api/limits) covers poll intervals and backoff. * [Hyperliquid WebSockets](/guides/hyperliquid/websockets/overview) documents every available channel and its payload. # Hyperliquid market explorer: open interest and order book Source: https://docs.uniblock.dev/guides/hyperliquid/analytics-dashboard/market-explorer Build a venue-wide Hyperliquid view: per-asset open interest, funding rates, a live L2 order book, and a real-time trade tape on Uniblock. The market explorer switches from one address to the whole venue: every perp asset with its mark price, open interest, funding rate and 24-hour change; a live order book for a selected coin; and a streaming tape of every fill on the exchange. ## 1. Build the market table The asset universe and its market context come from two types that must be read together: * **`meta`** gives the static universe: asset names, size decimals, max leverage. * **`webData2`** gives the live context per asset: mark price, open interest, funding, 24-hour volume. ```javascript theme={null} const [meta, webData] = await Promise.all([ info({ type: "meta" }), // webData2 is user-scoped, but its assetCtxs slice is global market context. // Any valid address works; the account sections are simply ignored. info( { type: "webData2", user: "0x0000000000000000000000000000000000000000" }, { provider: "goldrush" }, ), ]); ``` Pin `webData2` to GoldRush for this read. `webData2` is served by several providers, but they don't all populate the `assetCtxs` slice. Leave the request unpinned and the waterfall may hand you a response whose `assetCtxs` is an empty array, which renders every price, open interest, and funding cell in your table as null. Pinning removes the ambiguity. The `meta` read alongside it needs no pin: every provider serves it. ### The positional join Here's the part that's easy to get wrong. `webData2.assetCtxs` is a bare array with **no coin field on its entries**. It's joined to `meta.universe` **by index**, so that `assetCtxs[i]` is the context for `universe[i]`. ```json theme={null} { "universe": [ { "name": "BTC", "szDecimals": 5, "maxLeverage": 50 }, { "name": "ETH", "szDecimals": 4, "maxLeverage": 50 } ], "assetCtxs": [ { "markPx": "62150.0", "openInterest": "1284.5", "funding": "0.0000125", "prevDayPx": "61200.0", "dayNtlVlm": "482000000.0", "midPx": "62149.5", "oraclePx": "62148.0", "dayBaseVlm": "7820.4", "premium": "0.00003", "impactPxs": ["62149.0", "62150.0"] } ] } ``` Two consequences follow, and both are load-bearing: **Index alignment is the join key**, so you must not filter the universe before indexing into `assetCtxs`. Filtering delisted assets first shifts every subsequent index by one and silently mislabels the entire rest of the table, showing BTC's open interest against ETH. Filter *inside* the loop, after you've read `ctxs[i]`. **The arrays can be different lengths.** `assetCtxs` is not guaranteed to be as long as `universe`, so guard every access. ```javascript theme={null} function joinMarketRows(universe, ctxs) { const rows = []; for (let i = 0; i < universe.length; i++) { const asset = universe[i]; // Skip delisted assets HERE, after indexing, so alignment is preserved. if (!asset || asset.isDelisted) continue; const ctx = ctxs[i]; const markPx = ctx ? Number(ctx.markPx) : null; const prevDayPx = ctx ? Number(ctx.prevDayPx) : 0; rows.push({ coin: asset.name, szDecimals: asset.szDecimals, maxLeverage: asset.maxLeverage, markPx, midPx: ctx?.midPx != null ? Number(ctx.midPx) : null, // openInterest is in base units, so multiply by mark for USD notional. oiNotional: ctx && markPx !== null ? Number(ctx.openInterest) * markPx : null, funding: ctx ? Number(ctx.funding) : null, dayNtlVlm: ctx ? Number(ctx.dayNtlVlm) : null, change24h: ctx && markPx !== null && prevDayPx > 0 ? (markPx - prevDayPx) / prevDayPx : null, }); } return rows; } ``` A few field notes: * **`openInterest` is denominated in the base asset**, not USD. Multiply by `markPx` to get the notional figure people expect to see in a market table. * **`funding` is the current hourly rate** as a decimal, so `0.0000125` is `0.00125%` per hour. Multiply by `24 * 365` for the annualized figure if you display APR. * **`szDecimals`** is the asset's size precision. Use it to format sizes correctly rather than picking a fixed decimal count for the whole table. ## 2. Overlay live mids The `markPx` values in `assetCtxs` are a snapshot. Rather than re-polling `webData2` on a tight loop, reuse the live price store from the [wallet tracker](/guides/hyperliquid/analytics-dashboard/wallet-tracker#4-keep-mid-prices-live). The `allFills` stream is already giving you a last-trade price per coin, and it's the same one subscription regardless of how many assets you display. ```javascript theme={null} const displayRows = rows.map((row) => ({ ...row, // Live tick wins; fall back to the snapshot mid, then the snapshot mark. price: prices.get(row.coin) ?? row.midPx ?? row.markPx, })); ``` Refresh `webData2` on a slow interval of 30 to 60 seconds for the fields the tape can't give you (open interest, funding, 24-hour volume), and let the stream carry price. ## 3. Add a live order book `l2Book` is available over both REST and WebSocket. For a live book, subscribe: a polling loop costs a request per tick and still lags. ```javascript theme={null} ws.send( JSON.stringify({ method: "subscribe", subscription: { type: "l2Book", coin: "BTC" } }), ); ``` The `coin` field accepts a single asset (`"BTC"`) or an array (`["BTC", "ETH"]`). Omitting it streams every asset, at **50 credits per minute** rather than 0.5 per coin. Only take the wildcard if you genuinely need all 200-plus books. ```json theme={null} { "channel": "l2Book", "data": { "coin": "BTC", "time": 1753660812345, "levels": [ [{ "px": "62149.0", "sz": "1.24", "n": 5 }], [{ "px": "62151.0", "sz": "0.87", "n": 3 }] ] } } ``` `levels` is a two-element array, **`[bids, asks]`**, each sorted best-first. So `levels[0][0]` is the highest bid and `levels[1][0]` is the lowest ask. Each level carries `px` (price), `sz` (total size at that price) and `n` (number of orders). Cumulative depth, for a depth chart or a ladder: ```javascript theme={null} function cumulativeDepth(levels) { let cum = 0; return levels.map((l) => { const sz = Number(l.sz); cum += sz; return { px: Number(l.px), sz, n: l.n, cum }; }); } const [bids, asks] = book.levels; const bidDepth = cumulativeDepth(bids); const askDepth = cumulativeDepth(asks); const spread = Number(asks[0].px) - Number(bids[0].px); const midPrice = (Number(asks[0].px) + Number(bids[0].px)) / 2; ``` If you're rendering a book for one coin at a time, unsubscribe from the previous coin when the user switches. Subscriptions are billed per minute and matched for unsubscribe by exact body, so leaving old ones open is a slow, silent cost leak. For a high-frequency book you can subscribe to `l2BookDiff` instead: a full snapshot first, then per-block changed levels only, at a fifth the cost. You maintain the book locally, replacing each level and deleting it when `sz` is `"0"`. See the [WebSocket guide](/guides/quickstart-guides/hyperliquid-websocket-guide) for the snapshot/diff handling. ## 4. Add the trade tape You already have the subscription (`allFills`, opened for the price store), so the tape costs nothing extra. Same `[address, fill]` tuple envelope as `userFills`: ```javascript theme={null} const MAX_TAPE_ROWS = 200; const tape = []; ws.on("message", (raw) => { const msg = JSON.parse(raw.toString()); if (msg.channel !== "allFills" || !Array.isArray(msg.fills)) return; for (const [address, fill] of msg.fills) { if (!fill?.coin || !fill.px) continue; tape.unshift({ address, coin: fill.coin, side: fill.side === "B" ? "buy" : "sell", px: Number(fill.px), sz: Number(fill.sz), notional: Math.abs(Number(fill.px) * Number(fill.sz)), time: fill.time, }); } tape.length = Math.min(tape.length, MAX_TAPE_ROWS); }); ``` The `address` half of each tuple is what makes this more than a price ticker: it links each fill to a trader, so a "largest fills" view doubles as trader discovery. Click through to the [wallet tracker](/guides/hyperliquid/analytics-dashboard/wallet-tracker) for whoever just moved size. ```javascript theme={null} // Whale tape: only fills above a notional threshold. const whaleFills = tape.filter((f) => f.notional >= 100_000); ``` `allFills` carries the entire venue, with thousands of events per minute in active markets. Cap your buffer (as above), and never re-render per message. Accumulate into an array and flush to the UI on a timer. ## Next [Leaderboard](/guides/hyperliquid/analytics-dashboard/leaderboard) ranks traders using batch reads plus the same `allFills` stream. # Build a Hyperliquid Analytics Dashboard Source: https://docs.uniblock.dev/guides/hyperliquid/analytics-dashboard/overview Build a four-surface Hyperliquid analytics dashboard on Uniblock's Info API and WebSocket feed: wallet tracking, PnL, market data, and leaderboards. This series walks through building a **Hyperliquid analytics dashboard** on Uniblock: a wallet tracker, per-trader PnL analytics, a live market and order book explorer, and a trader leaderboard. Each page is self-contained, but they build in order, and the wallet tracker introduces the patterns the others reuse. Everything here runs on two Uniblock surfaces: * The [**Hyperliquid Info API**](/guides/hyperliquid/info-api/overview), a `POST /uni/v1/hyperliquid/info` dispatch endpoint where the body's `type` field selects the operation. * The [**GoldRush WebSocket**](/guides/hyperliquid/websockets/overview) at `wss://websocket.uniblock.dev/goldrush`, for order books and live fill streams. Create your project and grab your API key from the [Uniblock dashboard](https://dashboard.uniblock.dev). New to Hyperliquid's architecture? Read [HyperCore vs. HyperEVM](/guides/quickstart-guides/hypercore-vs-hyperevm) first. This series is entirely HyperCore (the native order book), not the EVM side. ## What you'll build | Surface | Answers | Page | | --------------- | ----------------------------------------------- | -------------------------------------------------------------------------- | | Wallet tracker | What does this address hold right now? | [Wallet tracker](/guides/hyperliquid/analytics-dashboard/wallet-tracker) | | PnL analytics | How has this address performed over time? | [PnL analytics](/guides/hyperliquid/analytics-dashboard/pnl) | | Market explorer | What's happening across the venue right now? | [Market explorer](/guides/hyperliquid/analytics-dashboard/market-explorer) | | Leaderboard | Who's winning, out of the traders I care about? | [Leaderboard](/guides/hyperliquid/analytics-dashboard/leaderboard) | ## Architecture: put a proxy in front Your API key must never reach the browser. For the REST side that's a familiar rule. For the WebSocket side it's a hard constraint: **browsers cannot set headers on a WebSocket handshake**, so browser code physically cannot authenticate to `wss://websocket.uniblock.dev/goldrush` with an `X-API-KEY` header. A small server-side bridge isn't a stylistic preference here; it's the only way to open the stream from a web app at all. The whole server is about forty lines: forward Info request bodies verbatim, and pipe WebSocket frames in both directions. ```javascript theme={null} import { createServer } from "node:http"; import { WebSocketServer, WebSocket } from "ws"; const API_KEY = process.env.UNIBLOCK_API_KEY; const INFO_URL = "https://api.uniblock.dev/uni/v1/hyperliquid/info"; const WSS_URL = "wss://websocket.uniblock.dev/goldrush"; // --- REST: forward the body verbatim, inject the key --- const server = createServer(async (req, res) => { if (req.method !== "POST" || !req.url.startsWith("/api/info")) { res.writeHead(404).end(); return; } const url = new URL(req.url, "http://localhost"); const upstream = new URL(INFO_URL); upstream.searchParams.set("chainId", url.searchParams.get("chainId") ?? "999"); // Let the client pin a provider when it needs one (see below). const provider = url.searchParams.get("provider"); if (provider) upstream.searchParams.set("provider", provider); const chunks = []; for await (const chunk of req) chunks.push(chunk); const r = await fetch(upstream, { method: "POST", headers: { "X-API-KEY": API_KEY, "content-type": "application/json" }, body: Buffer.concat(chunks), }); res.writeHead(r.status, { "content-type": "application/json" }); res.end(Buffer.from(await r.arrayBuffer())); }); // --- WebSocket: bridge browser <-> Uniblock, inject the key --- const wss = new WebSocketServer({ noServer: true }); server.on("upgrade", (req, socket, head) => { if (new URL(req.url, "http://localhost").pathname !== "/ws") return socket.destroy(); wss.handleUpgrade(req, socket, head, (client) => { const upstream = new WebSocket(WSS_URL, { headers: { "X-API-KEY": API_KEY } }); const pending = []; // The browser may subscribe before the upstream socket is open, so buffer until then. upstream.on("open", () => { for (const msg of pending) upstream.send(msg); pending.length = 0; }); upstream.on("message", (data) => { if (client.readyState === WebSocket.OPEN) client.send(data); }); client.on("message", (data) => { const msg = data.toString(); if (upstream.readyState === WebSocket.OPEN) upstream.send(msg); else pending.push(msg); }); const closeBoth = () => { client.close(); upstream.close(); }; client.on("close", closeBoth); upstream.on("close", closeBoth); upstream.on("error", closeBoth); }); }); server.listen(8787); ``` Every REST example in this series calls `POST /api/info` against that proxy. To keep the snippets readable, they all assume this helper: ```javascript theme={null} async function info(body, opts = {}) { const qs = new URLSearchParams({ chainId: "999", ...opts }); const res = await fetch(`/api/info?${qs}`, { method: "POST", headers: { "content-type": "application/json" }, body: JSON.stringify(body), }); if (!res.ok) throw new Error(`info ${body.type} failed: ${res.status}`); return res.json(); } ``` ## Two conventions that apply everywhere ### Numbers arrive as decimal strings Hyperliquid returns almost every number as a string: `"1234.5"`, not `1234.5`. This is deliberate: it preserves exact decimal precision that IEEE-754 floats would lose. Keep values as strings while you carry them around, and convert only at the point you do display math: ```javascript theme={null} // Wrong. String concatenation, not addition: "7500.00" + "42.10" === "7500.0042.10" const wrong = position.positionValue + position.unrealizedPnl; // Right. Convert at the edge, where you're formatting const right = Number(position.positionValue) + Number(position.unrealizedPnl); ``` ### `chainId` selects the network `999` is Hyperliquid mainnet (the default), `998` is testnet. Every example here uses mainnet. ## Which provider serves what Uniblock routes each Info request through a provider waterfall: Alchemy, Dwellir, Chainstack, GoldRush, in that priority order. **Different providers serve different Info types**, and that has a practical consequence: the historical and market-data types this series leans on are served by GoldRush alone. | Info `type` | Alchemy | Dwellir | Chainstack | GoldRush | Used by | | ------------------------ | :-----: | :-----: | :--------: | :------: | ------------------- | | `portfolioState` | ✓ | ✓ | ✓ | ✓ | Wallet, Leaderboard | | `batchPortfolioStates` | ✓ | ✓ | ✓ | ✓ | Leaderboard | | `clearinghouseState` | ✓ | ✓ | ✓ | ✓ | Wallet | | `spotClearinghouseState` | ✓ | ✓ | ✓ | ✓ | Wallet | | `openOrders` | ✓ | ✓ | ✓ | ✗ | Wallet | | `frontendOpenOrders` | ✓ | ✓ | ✓ | ✓ | Wallet | | `meta` | ✓ | ✓ | ✓ | ✓ | Market explorer | | `webData2` | ✓ | ✗ | ✓ | ✓ | Market explorer | | `allMids` | ✗ | ✗ | ✗ | ✓ | Market explorer | | `l2Book` | ✗ | ✗ | ✗ | ✓ | Market explorer | | `candleSnapshot` | ✗ | ✗ | ✗ | ✓ | PnL | | `userFills` | ✗ | ✗ | ✗ | ✓ | Wallet, PnL | | `userFillsByTime` | ✗ | ✗ | ✗ | ✓ | PnL | | `userFunding` | ✗ | ✗ | ✗ | ✓ | PnL | You don't normally need to act on this, because the waterfall automatically picks a provider that serves your `type`. It matters in two situations: * **Debugging.** If a response looks wrong, pinning `?provider=` lets you compare providers directly and find out whether you're looking at a routing artifact or real data. * **Consistency.** If you want two related reads to come from the same source, pin both. `openOrders` is the one asymmetry worth remembering: GoldRush serves `frontendOpenOrders` but not `openOrders`. If you want your open-orders read to survive a failover to GoldRush, use `frontendOpenOrders`. It returns the same orders with extra frontend metadata. ## Cost model Two meters run, and they behave differently. **REST is billed per request.** A batch type multiplies: `batchPortfolioStates` over 50 addresses is billed as 50 lookups, not one. That's still far cheaper than 50 separate requests, but it isn't free. **WebSocket is billed per subscription-minute**, and the rate depends on the channel: | Channel | Rate | Wildcard (no `coin`) | | -------------------------------------------------------------------------------------- | ---------------------------- | --------------------- | | `l2Book` | 0.5 / coin / min | 50 / min (all assets) | | `l2BookDiff` | 0.1 / coin / min | 10 / min (all assets) | | `l4Book` | 2 / coin / min (**BTC: 20**) | not supported | | `allFills`, `userFills`, `orderUpdates`, `builderFills`, `userNonFundingLedgerUpdates` | 1 / min | n/a | The shape of that table is the whole argument for scoping your subscriptions: subscribing to `l2Book` for three coins costs 1.5/min; omitting `coin` to get all of them costs 50/min, over thirty times more for data you'll mostly discard. The general rule that follows: **prefer one WebSocket subscription over a polling loop.** A stream you hold open for an hour costs 60 units; polling the same data every two seconds costs 1,800 requests. Where you must poll, poll slowly and back off on `429`. Routing through Uniblock removes Hyperliquid's per-IP request-weight cap, but your plan's rate limits still apply, and bursts return `429`. See [Rate limits, caching & polling](/guides/hyperliquid/info-api/limits). ## Next Start with the [wallet tracker](/guides/hyperliquid/analytics-dashboard/wallet-tracker): it introduces account state, live prices, and your first WebSocket subscription. # Hyperliquid PnL analytics: realized PnL, fees, and win rate Source: https://docs.uniblock.dev/guides/hyperliquid/analytics-dashboard/pnl Derive realized PnL, fees, funding, win rate, and per-coin breakdowns for any Hyperliquid address from its fill history on Uniblock. Hyperliquid doesn't hand you a PnL curve; it hands you fills. Every fill that reduces a position carries the profit or loss that closing it realized, so a trader's whole performance history is derivable from `userFillsByTime` plus `userFunding`. This page builds the derivation: realized PnL over time, fees, funding, win rate, volume, and a per-coin breakdown. `userFills`, `userFillsByTime`, `userFunding`, and `candleSnapshot` are all served by GoldRush. The waterfall routes to it automatically, so you only need `?provider=goldrush` if you're pinning for consistency or debugging. ## 1. Fetch the fill history `userFillsByTime` takes a millisecond-epoch window. `endTime` is optional and defaults to now. ```javascript theme={null} const now = Date.now(); const startTime = now - 30 * 24 * 60 * 60 * 1000; // last 30 days const fills = await info({ type: "userFillsByTime", user: address, startTime }); ``` Each fill carries everything the derivation needs: ```json theme={null} { "coin": "ETH", "px": "2410.5", "sz": "1.5", "side": "A", "time": 1753660812345, "startPosition": "1.5", "dir": "Close Long", "closedPnl": "128.40", "hash": "0x...", "oid": 88123456, "fee": "1.81", "tid": 445566778899 } ``` The two load-bearing fields: * **`closedPnl`** is the realized profit or loss from the portion of the position that this fill closed. It's `"0.0"` on fills that only *open* or *increase* a position, because nothing was realized. Only closing fills carry a non-zero value. * **`fee`** is what you paid to trade, always positive, and always deducted. A negative fee (a maker rebate) appears as a negative value, which the arithmetic below handles without a special case. ### Handling the 2000-fill cap Hyperliquid caps a fills response at **2000 rows**, keeping the most recent. For an active trader over a long window, that's a truncated view, and nothing in the response tells you it happened. You have to infer it: ```javascript theme={null} const FILL_CAP = 2000; const truncated = fills.length >= FILL_CAP; ``` To reconstruct a full history, page backwards: fetch a window, and if you hit the cap, fetch again ending just before the oldest fill you received. ```javascript theme={null} // Not every fill is backed by a real trade. Synthetic fills (spot dust conversions // are the common case) carry `tid: 0` and a zero `hash`, so one account can hold // dozens of distinct fills sharing both. Compose the key from fields that stay // distinct across them. const fillKey = (f) => `${f.tid}:${f.oid}:${f.time}:${f.coin}`; async function fetchAllFills(address, startTime) { const all = []; let endTime = Date.now(); while (true) { const page = await info({ type: "userFillsByTime", user: address, startTime, endTime }); if (page.length === 0) break; all.push(...page); if (page.length < FILL_CAP) break; // partial page, so we've reached the start // Step back to just before the oldest fill in this page. const oldest = Math.min(...page.map((f) => f.time)); if (oldest <= startTime) break; endTime = oldest - 1; } // Pages can overlap at boundaries, so de-duplicate, but not on `tid` alone. return [...new Map(all.map((f) => [fillKey(f), f])).values()]; } ``` Don't de-duplicate on `tid` by itself. It's a *trade* id, and fills that aren't trades don't have one. A spot dust conversion is emitted with `tid: 0` and `hash: "0x000…0"`. Key a map on `tid` and an account with 42 dust conversions collapses to a single row, quietly undercounting volume, fill count, and per-coin activity. Each page is a billed request, so an unbounded backfill over a very active address can be expensive. Bound the loop: cap the number of pages, or show the truncated window with a "showing the most recent 2000 fills" note and let the user opt in to the full history. ## 2. Derive the numbers With the fills in hand, everything else is arithmetic. Sort oldest-first, walk once, and accumulate. ```javascript theme={null} // Does this fill reduce or flip exposure? `dir` is Hyperliquid's own description of // what the fill did to the position, so read it rather than inferring from PnL. // "Open Long" / "Open Short" → adds exposure // "Close Long" / "Close Short" → reduces it // "Long > Short" / "Short > Long" → flips it (closes, then reopens) // "Liquidated …" / "Auto-Deleveraged …" → closed involuntarily // "Spot Dust Conversion", "Buy", "Sell" → spot, no perp exposure at all function isClosingFill(f) { const dir = f.dir ?? ""; return dir.includes("Close") || dir.includes(">") || /^(Liquidated|Auto-Deleveraged)/.test(dir); } function derivePnl(fills) { const asc = [...fills].sort((a, b) => a.time - b.time); const series = []; // cumulative realized PnL, one point per fill const coins = new Map(); // per-coin breakdown let cumulative = 0; let fees = 0; let volume = 0; let closingFills = 0; let wins = 0; for (const f of asc) { const closedPnl = Number(f.closedPnl); const fee = Number(f.fee); const notional = Math.abs(Number(f.px) * Number(f.sz)); cumulative += closedPnl - fee; fees += fee; volume += notional; // Win rate counts only fills that closed exposure. Opening fills must not enter // the denominator, since including them would tank the rate for everyone. if (isClosingFill(f)) { closingFills++; if (closedPnl > 0) wins++; } series.push({ time: f.time, value: cumulative }); const row = coins.get(f.coin) ?? { coin: f.coin, realizedPnl: 0, volume: 0, fills: 0 }; row.realizedPnl += closedPnl - fee; row.volume += notional; row.fills++; coins.set(f.coin, row); } return { series, realizedPnl: cumulative, fees, volume, totalFills: asc.length, closingFills, winRate: closingFills > 0 ? wins / closingFills : null, byCoin: [...coins.values()].sort((a, b) => b.volume - a.volume), truncated: asc.length >= 2000, }; } ``` Three definitions in that function are worth stating explicitly, because they're the ones people get wrong: **Realized PnL is net of fees.** `Σ(closedPnl − fee)`. Hyperliquid's `closedPnl` is gross, so it doesn't deduct what you paid to trade. Report gross PnL as "realized PnL" and your numbers will consistently overstate performance, by more the more actively the address trades. **Volume is notional, `Σ|px × sz|`.** The absolute value matters: `sz` can be negative depending on direction, and a trader's volume is a magnitude, not a signed quantity. **Win rate is wins ÷ *closing* fills**, not wins ÷ all fills. Every position takes at least one opening fill that realizes nothing, so dividing by the total fill count silently halves the win rate of anyone who opens and closes in single fills, and distorts it unpredictably for everyone else. Get the denominator from `dir`, not from `closedPnl`. The tempting shortcut ("a closing fill is one where `closedPnl ≠ 0`") is wrong in both directions. A position closed exactly at its entry price realizes nothing and would be dropped from the denominator, inflating the win rate of anyone who scratches trades. And a spot dust conversion also carries `closedPnl: 0` despite touching no perp position at all. `dir` states what the fill actually did, so it answers the question directly. This derivation covers **realized** PnL only: settled facts from closed positions. It deliberately excludes unrealized PnL on positions still open. If your dashboard shows a combined figure, compute the unrealized half separately from live positions and mids (see the [wallet tracker](/guides/hyperliquid/analytics-dashboard/wallet-tracker#4-keep-mid-prices-live)), and label the two clearly. Mixing them into one number produces a figure that jumps around with the market and reconciles against nothing. ## 3. Add funding Perp traders pay or receive funding continuously, and over a long holding period it can dominate trading PnL. It's a separate ledger from fills: ```javascript theme={null} const funding = await info({ type: "userFunding", user: address, startTime }); ``` ```json theme={null} [ { "time": 1753660800000, "hash": "0x...", "delta": { "type": "funding", "coin": "BTC", "usdc": "-0.42", "szi": "0.12", "fundingRate": "0.0000125" } } ] ``` `delta.usdc` is **signed**: negative is funding you paid, positive is funding you received. So the accumulation is a plain sum, no sign flip: ```javascript theme={null} function deriveFunding(updates) { const asc = [...updates].sort((a, b) => a.time - b.time); const series = []; let net = 0; for (const u of asc) { net += Number(u.delta.usdc); // + received, − paid series.push({ time: u.time, value: net }); } return { series, net }; } ``` Keep funding on its own line rather than folding it into realized PnL. They answer different questions (one is trading skill, the other is carry cost) and a trader whose strategy is profitable but whose funding bill exceeds it needs to see both. ## 4. Add price context A PnL curve is easier to read against the market it was earned in. `candleSnapshot` supplies the backdrop. This is the one type in the series with a **nested request body**. Its parameters go inside a `req` object rather than at the top level: ```javascript theme={null} const candles = await info({ type: "candleSnapshot", req: { coin: "BTC", interval: "1h", startTime, endTime: Date.now() }, }); ``` ```json theme={null} [ { "t": 1753657200000, "T": 1753660799999, "s": "BTC", "i": "1h", "o": "62010.0", "c": "62150.0", "h": "62300.0", "l": "61890.0", "v": "142.85", "n": 3218 } ] ``` Candles arrive oldest-first. The keys are terse: `t` open time, `T` close time, `s` coin, `i` interval, `o`/`h`/`l`/`c` the OHLC prices, `v` volume, `n` trade count. Match the interval to the window so the chart stays readable rather than returning thousands of points: ```javascript theme={null} function intervalForWindow(days) { return days <= 7 ? "1h" : days <= 30 ? "4h" : "1d"; } ``` ## 5. Assemble the surface ```javascript theme={null} async function loadPnl(address, days) { const startTime = Date.now() - days * 24 * 60 * 60 * 1000; const [fills, funding] = await Promise.all([ info({ type: "userFillsByTime", user: address, startTime }), info({ type: "userFunding", user: address, startTime }), ]); const pnl = derivePnl(fills); const fundingDerivation = deriveFunding(funding); return { ...pnl, funding: fundingDerivation, net: pnl.realizedPnl + fundingDerivation.net, }; } ``` A reasonable set of headline tiles from that: **realized PnL** (net of fees), **funding**, **fees paid**, **volume**, **win rate**, and **fill count**, with the cumulative `series` as the chart and `byCoin` as a sortable table underneath. Surface `truncated` in the UI. A user comparing a 90-day figure against their own records will otherwise conclude your numbers are wrong, when in fact the window was capped. One line, "showing the most recent 2000 fills", turns a bug report into understood behavior. ## Next [Market explorer](/guides/hyperliquid/analytics-dashboard/market-explorer) moves from one address to the whole venue. # Hyperliquid wallet tracker: positions, balances, live fills Source: https://docs.uniblock.dev/guides/hyperliquid/analytics-dashboard/wallet-tracker Build a Hyperliquid wallet tracker that shows perp positions, spot balances, open orders, live unrealized PnL, and a real-time fill feed for any address. The wallet tracker answers *what does this address hold right now?*: open perp positions with entry, mark, and liquidation prices, spot balances, resting orders, and a live fill feed that ticks as the address trades. This page introduces three patterns the rest of the series reuses: reading account state, maintaining a live mid-price store, and subscribing to a user-scoped WebSocket channel. All examples use the `info()` helper and the key-holding proxy from the [series overview](/guides/hyperliquid/analytics-dashboard/overview). ## 1. Read account state You have two options, and the choice is about how much normalization you want. **`portfolioState`** is a Uniblock synthetic type: one call returns perps, spot, and account-abstraction mode composed into a single object, with each section isolated so a failure in one doesn't take down the others. ```javascript theme={null} const portfolio = await info({ type: "portfolioState", user: address }); // { // type: "portfolioState", // address: "0x...", // chainId: 999, // perpetuals: { marginSummary, assetPositions, withdrawable, ... } | null, // spot: { balances: [...] } | null // } ``` Note that `perpetuals` and `spot` are **nullable**. A section that failed upstream comes back `null` rather than throwing, so guard before you read into it. **`clearinghouseState`** and **`spotClearinghouseState`** are the native Hyperliquid reads, if you'd rather compose them yourself: ```javascript theme={null} const [perps, spot] = await Promise.all([ info({ type: "clearinghouseState", user: address }), info({ type: "spotClearinghouseState", user: address }), ]); ``` Either way, the perp payload has the same shape: ```json theme={null} { "marginSummary": { "accountValue": "1250.44", "totalNtlPos": "8300.10", "totalRawUsd": "1250.44", "totalMarginUsed": "415.00" }, "crossMarginSummary": { "...": "same fields" }, "crossMaintenanceMarginUsed": "83.00", "withdrawable": "835.44", "assetPositions": [ { "type": "oneWay", "position": { "coin": "BTC", "szi": "0.12", "entryPx": "62150.0", "positionValue": "7500.00", "unrealizedPnl": "42.10", "returnOnEquity": "0.0562", "liquidationPx": "48120.5", "leverage": { "type": "cross", "value": 10 }, "marginUsed": "750.00" } } ], "time": 1753660800000 } ``` **`marginSummary.accountValue` is perps margin only: it does not include vault equity.** A wallet with a large vault stake can show a small `accountValue` here while actually holding far more. Rendering this field alone as "Account Value" or "Total Value" understates such wallets, sometimes by orders of magnitude. Join it with `userVaultEquities` (one extra Info call per wallet), which returns the wallet's vault deposits as vault-address/equity pairs. Fetch the two independently so a failure in one doesn't take down the other, because `Promise.all` rejects the whole pair the moment either call throws, which is exactly the failure case you're trying to degrade gracefully from: ```javascript theme={null} const [perps, vaultEquities] = await Promise.all([ info({ type: "clearinghouseState", user: address }).catch(() => null), info({ type: "userVaultEquities", user: address }).catch(() => null), ]); function toFiniteNumber(value) { if (value === null || value === undefined) return null; const trimmed = String(value).trim(); if (trimmed === "") return null; // Number(" ") is 0, so whitespace is blank too const parsed = Number(trimmed); return Number.isFinite(parsed) ? parsed : null; } // Blank or unparseable accountValue is unknown, not $0. Number("") is 0, and // rendering that as a real figure is the same species of lie as the missing vault leg. const perpsMargin = perps ? toFiniteNumber(perps.marginSummary.accountValue) : null; let unweighed = 0; const vaultEquity = vaultEquities === null ? null // the vault call itself failed; don't fold that into a silent 0 : vaultEquities.reduce((sum, v) => { const equity = toFiniteNumber(v.equity); if (equity === null) unweighed++; // counted, not silently dropped; see below return sum + (equity ?? 0); }, 0); const knownValue = perpsMargin === null || vaultEquity === null ? null : perpsMargin + vaultEquity; ``` **Don't call this a total, and don't stop at two of three buckets.** Perps margin + vault equity still leaves out spot balances, and `spotClearinghouseState` gives you a cost basis (`entryNtl`), not a mark price, so valuing spot needs `spotMeta` and spot mids on top. Naming the perps+vault sum "Total Value" just moves the same understatement to a different set of wallets (spot-heavy ones instead of vault-heavy ones). Call the field something honest about its scope, such as `knownValue` or "Perps + Vaults", until spot is actually priced in. Two honesty rules matter more than the arithmetic: * if the vault call **failed** outright, treat the contribution as `null`, not `0`. A figure that silently falls back to perps-only margin looks complete but understates the wallet exactly as before. * a single stake whose `equity` string doesn't parse (`unweighed` above) is different from a failed call: the call succeeded, one entry just isn't numeric. Counting it as 0 keeps `knownValue` a **floor** rather than discarding the whole scan over one bad entry, but the UI must say so: show a `(floor)` qualifier whenever `unweighed > 0`, so the figure never reads as complete when it isn't. That gives three display states, not two: * `perpsMargin` and `vaultEquity` both known → render the combined figure **and** a labelled **Perps Margin** tile side by side. Collapsing them into one number loses the perps-only figure some readers specifically want. * `perpsMargin` known, `vaultEquity` `null` → render **only** the Perps Margin tile, noting the vault call failed. There is no combined figure to show. * `perps` is `null` → render neither metric; report that the perps request failed. * `perps` is available but `perpsMargin` is `null` (blank or unparseable `accountValue`) → render neither metric; report the value as unavailable. This is a data-quality gap, not a request failure, so don't word it as one. ## 2. Render the positions table Positions live one level down, under `assetPositions[].position`. The field that trips people up is `szi`, which is the **signed** position size, so its sign is what tells you long from short. There is no `side` field. ```javascript theme={null} const positions = (perps?.assetPositions ?? []).map(({ position: p }) => ({ coin: p.coin, side: Number(p.szi) > 0 ? "long" : "short", size: Math.abs(Number(p.szi)), entryPx: Number(p.entryPx), // null for a cross-margin position that can't be individually liquidated liquidationPx: p.liquidationPx === null ? null : Number(p.liquidationPx), leverage: `${p.leverage.value}x ${p.leverage.type}`, marginUsed: Number(p.marginUsed), unrealizedPnl: Number(p.unrealizedPnl), })); ``` `liquidationPx` is legitimately `null` for some positions. Cross-margin positions don't each have their own liquidation price, since the whole account is collateral. Render a dash, not a zero. Spot balances are flatter: ```javascript theme={null} const balances = (spot?.balances ?? []).map((b) => ({ coin: b.coin, total: Number(b.total), available: Number(b.total) - Number(b.hold), // `hold` is locked in resting orders entryNtl: Number(b.entryNtl), })); ``` ## 3. Show open orders ```javascript theme={null} const orders = await info({ type: "frontendOpenOrders", user: address }); // [{ coin, side, limitPx, sz, oid, timestamp, origSz, cloid? }] ``` `side` is `"B"` for bid (buy) and `"A"` for ask (sell), Hyperliquid's convention throughout, in fills as well as orders. `sz` is what's left unfilled; `origSz` is what the order was placed for, so `origSz - sz` is the filled portion. Use `frontendOpenOrders` rather than `openOrders` unless you have a reason not to. Both return the same resting orders, but `frontendOpenOrders` adds order-type and trigger metadata, and it's served by all four providers, whereas `openOrders` is not served by GoldRush. If your request fails over to GoldRush, `frontendOpenOrders` keeps working. ## 4. Keep mid prices live Positions are only half the picture: `unrealizedPnl` in the snapshot was true at `time`, and it drifts the moment the market moves. To keep it live you need a current mark for each coin. **There is no `allMids` WebSocket channel.** This is the single most common wrong assumption when building on this stack: the REST type exists, so people look for the matching stream and don't find one. The working pattern is a hybrid: * **Seed and correct** from REST `allMids` on a slow interval (30 seconds is plenty). * **Update tick-by-tick** from the `allFills` WebSocket channel, taking each fill's price as the latest trade price for its coin. ```javascript theme={null} const prices = new Map(); // Seed from REST, and re-seed slowly to correct any drift. async function seedPrices() { const mids = await info({ type: "allMids" }); // { "BTC": "62150.0", "ETH": "2410.5", ... } for (const [coin, px] of Object.entries(mids)) prices.set(coin, Number(px)); } await seedPrices(); setInterval(seedPrices, 30_000); // Update from the live trade stream. ws.send(JSON.stringify({ method: "subscribe", subscription: { type: "allFills" } })); ws.on("message", (raw) => { const msg = JSON.parse(raw.toString()); if (msg.channel !== "allFills") return; for (const [, fill] of msg.fills) { if (fill?.coin && fill.px) prices.set(fill.coin, Number(fill.px)); } }); ``` Two things to note about that subscription, both covered in full in the next section: `allFills` needs no parameters (it's the whole venue), and its payload arrives as `[address, fill]` **tuples**, which is why the loop destructures past the address. `allFills` is a busy stream, with thousands of events a minute at peak. Don't re-render on every message. Batch price updates and flush on a timer (250ms works well) so a busy market doesn't pin your UI thread. With a live price map, unrealized PnL becomes a derivation rather than a fetch: ```javascript theme={null} function liveUnrealizedPnl(positions) { return positions.reduce((sum, p) => { const mid = prices.get(p.coin); // Fall back to the snapshot value until the first price for that coin arrives. if (mid === undefined) return sum + Number(p.unrealizedPnl); return sum + Number(p.szi) * (mid - Number(p.entryPx)); }, 0); } ``` Because `szi` is signed, that one expression is correct for both directions: a short has negative `szi`, so a falling price yields a positive product. ## 5. Stream this wallet's fills Finally, subscribe to the address's own fills for a live activity feed. ```javascript theme={null} ws.send( JSON.stringify({ method: "subscribe", subscription: { type: "userFills", addresses: [address] }, }), ); ``` **`userFills` takes `addresses: string[]`, not `user: string`.** This diverges from Hyperliquid's native WebSocket contract, and it fails quietly: send the native `{ type: "userFills", user: "0x..." }` form and the subscription is accepted but never delivers anything. The same applies to `orderUpdates`. If a user-scoped stream is silent, check this first. The payload diverges too. Fills arrive as **`[address, fill]` tuples** under a `fills` key, not in Hyperliquid's native `{ data: { user, fills } }` envelope: ```json theme={null} { "channel": "userFills", "fills": [ [ "0xabc...", { "coin": "BTC", "px": "62180.0", "sz": "0.02", "side": "B", "time": 1753660812345, "startPosition": "0.10", "dir": "Open Long", "closedPnl": "0.0", "hash": "0x...", "oid": 88123456, "fee": "0.37", "tid": 445566778899 } ] ] } ``` Because `allFills` and `userFills` share that envelope, one parser handles both: ```javascript theme={null} function parseFillTuples(msg) { if (!Array.isArray(msg.fills)) return []; return msg.fills.filter(([address, fill]) => typeof address === "string" && fill?.coin); } ws.on("message", (raw) => { const msg = JSON.parse(raw.toString()); if (msg.channel !== "userFills") return; for (const [, fill] of parseFillTuples(msg)) { feed.unshift({ coin: fill.coin, side: fill.side === "B" ? "buy" : "sell", px: Number(fill.px), sz: Number(fill.sz), // Human-readable already: "Open Long", "Close Short", "Long > Short", … dir: fill.dir, pnl: Number(fill.closedPnl), time: fill.time, }); } }); ``` The `dir` field is worth surfacing directly in the feed. It is a pre-formatted description of what the fill did to the position, which saves you inferring it from `startPosition` and `szi`. Subscriptions are matched for unsubscribe by their **exact** body. Send `{ method: "unsubscribe", subscription: { type: "userFills", addresses: [address] } }` with the identical `addresses` array you subscribed with, or the subscription (and its per-minute billing) stays open. When a user switches wallets, unsubscribe the old address before subscribing the new one. ## Reconnecting The stream will drop. Handle it with exponential backoff, and re-send every active subscription on reconnect, because the server keeps no state across connections: ```javascript theme={null} let retry = 0; function connect() { const ws = new WebSocket("ws://localhost:8787/ws"); ws.on("open", () => { retry = 0; for (const sub of activeSubscriptions) { ws.send(JSON.stringify({ method: "subscribe", subscription: sub })); } }); ws.on("close", () => { setTimeout(connect, Math.min(15_000, 500 * 2 ** retry++)); }); return ws; } ``` ## Next The wallet tracker shows the present. Next, [PnL analytics](/guides/hyperliquid/analytics-dashboard/pnl) reconstructs the past from fill history. # Hyperliquid EVM Overview Source: https://docs.uniblock.dev/guides/hyperliquid/evm/overview Standard JSON-RPC access to HyperEVM (chain 999, testnet 998) through Uniblock: read state, send transactions, and call contracts with familiar EVM tooling. **HyperEVM** is Hyperliquid's EVM-compatible chain: the layer where you deploy standard Solidity contracts and interact with Hyperliquid using the same JSON-RPC methods you'd use on any other EVM chain. Uniblock exposes HyperEVM through its unified JSON-RPC endpoint, so you get low-latency routing and automatic provider failover behind one API key. HyperEVM is the permissionless, contract-programmable half of Hyperliquid. HyperCore (the native order book) is reached through the [Info API](/guides/hyperliquid/info-api/overview) and [WebSockets](/guides/hyperliquid/websockets/overview) instead. See [HyperCore vs. HyperEVM](/guides/quickstart-guides/hypercore-vs-hyperevm). ## Endpoint Send a `POST` request to the unified JSON-RPC endpoint with the chain ID in the query string: ```plaintext theme={null} https://api.uniblock.dev/uni/v1/json-rpc?chainId=999 ``` Include the JSON-RPC `method` and `params` in the request body, authenticated with your `x-api-key` header. ## Supported networks | Network | Symbol | Type | Chain ID | | ------------------- | ------ | ------- | -------- | | Hyperliquid | `HYPE` | Mainnet | `999` | | Hyperliquid Testnet | `HYPE` | Testnet | `998` | ## Method groups HyperEVM supports the standard EVM JSON-RPC surface plus extended namespaces. Browse the full reference: Core `eth_*` methods: blocks, balances, transactions, logs, and contract calls. Low-level `debug_*` methods for tracing and state inspection. `trace_*` methods for transaction and block-level execution traces. `erigon_*` methods for header and receipt lookups. `ots_*` methods powering block-explorer style queries. ## Next steps Make your first HyperEVM JSON-RPC call in under two minutes. # Query HyperEVM Source: https://docs.uniblock.dev/guides/hyperliquid/evm/quickstart Make your first HyperEVM JSON-RPC call on Uniblock in under two minutes with cURL, ethers.js, or viem against chain 999 mainnet or 998 testnet. Estimated time: under two minutes. This guide assumes you already have an Uniblock project; if not, follow the [Uniblock Quickstart Guide](/guides/getting-started/uniblock-quickstart-guide) first. Replace `YOUR_API_KEY` with the key from your [Uniblock dashboard](https://dashboard.uniblock.dev). Use `chainId=999` for mainnet or `998` for testnet. ## Raw JSON-RPC Read the latest HyperEVM block number: ```bash cURL theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/json-rpc?chainId=999' \ --header 'x-api-key: YOUR_API_KEY' \ --header 'Content-Type: application/json' \ --data '{ "jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": 1 }' ``` ```javascript JavaScript theme={null} const res = await fetch( "https://api.uniblock.dev/uni/v1/json-rpc?chainId=999", { method: "POST", headers: { "x-api-key": "YOUR_API_KEY", "Content-Type": "application/json", }, body: JSON.stringify({ jsonrpc: "2.0", method: "eth_blockNumber", params: [], id: 1, }), }, ); console.log(await res.json()); // { jsonrpc: "2.0", id: 1, result: "0x..." } ``` ## With a standard EVM library Because HyperEVM speaks standard JSON-RPC, point any EVM library at the Uniblock endpoint. The `x-api-key` header travels in the transport config. ```javascript viem theme={null} import { createPublicClient, http } from "viem"; const client = createPublicClient({ transport: http("https://api.uniblock.dev/uni/v1/json-rpc?chainId=999", { fetchOptions: { headers: { "x-api-key": "YOUR_API_KEY" } }, }), }); console.log(await client.getBlockNumber()); ``` ```javascript ethers theme={null} import { JsonRpcProvider, FetchRequest } from "ethers"; const req = new FetchRequest( "https://api.uniblock.dev/uni/v1/json-rpc?chainId=999", ); req.setHeader("x-api-key", "YOUR_API_KEY"); const provider = new JsonRpcProvider(req); console.log(await provider.getBlockNumber()); ``` ## Next steps * Browse every method group in the [HyperEVM overview](/guides/hyperliquid/evm/overview). * See the full method reference in the [Hyperliquid (HYPE) JSON-RPC docs](/reference/jsonrpc/999/hyperliquid-overview). * Need the native order book instead of the EVM layer?

Explore all available endpoints and interactive playgrounds # Rate Limits, Caching & Polling Source: https://docs.uniblock.dev/guides/hyperliquid/info-api/limits How Uniblock's Hyperliquid Info API removes the public request-weight cap, meters usage in compute units, and how to poll and cache efficiently. Hyperliquid's public `/info` API enforces a request-weight budget per IP address, so high-frequency polling and multi-user reads quickly hit the ceiling. Routing through Uniblock removes that constraint: usage is metered in **compute units** against your project instead of throttled per IP. Usage is billed in compute units. See [Compute units & pricing](/reference/resources/pricing-plans) for how metering and plans work. ## No public request-weight cap The public API assigns each `/info` operation a weight and limits the total weight per minute per IP. Uniblock does not apply that per-IP cap. Instead: * Requests are metered in compute units per call, not throttled by a per-IP weight budget. * Uniblock's provider waterfall spreads load and fails over automatically, so a single provider's limits don't become yours. This removes the *per-IP* cap; it does not make the API unlimited. Your project still has **plan-level rate limits**: bursts above your plan's allowance return `429`, and backup routing does not bypass them. Keep retry/backoff logic in place. See [Rate limits](/guides/uniblock/error-codes#rate-limits). ## Poll efficiently Without the per-IP cap you can poll harder, but do it deliberately; you're billed per request and still bound by your plan's rate limit: * **Match your poll interval to how fast the data changes.** Order books and mark prices move every block; account state changes far less often. * **Batch multi-user reads.** Replace one request per user with a single synthetic batch type: `batchClearinghouseStates` or `batchPortfolioStates` (up to 50 users per request). See the [Info API overview](/guides/hyperliquid/info-api/overview). * **Stream instead of poll for order books.** If you're polling `l2Book` on a tight loop, switch to the [WebSocket `l2BookDiff` channel](/guides/hyperliquid/websockets/l2-book-diff): you get per-block updates without repeated REST calls. ## Cache read-mostly data Some `/info` responses change rarely and are safe to cache client-side: | Data | Typical cache window | | ------------------------------------------- | ---------------------------- | | `meta`, `spotMeta` (asset universe) | minutes to hours | | `metaAndAssetCtxs` (contexts + mark prices) | seconds | | `clearinghouseState`, `portfolioState` | seconds | | `l2Book` | do not cache; stream instead | Cache the slow-moving metadata once at startup and refresh it on a long interval, rather than fetching it alongside every hot read. ## Handling errors * A body without a supported `type` returns `400` at the HTTP boundary before reaching a provider; validate your `type` client-side. * A `429` means your project exceeded its plan-level rate limit; retry with exponential backoff and jitter, and upgrade your plan if demand is sustained. * Transient upstream failures are retried across the provider waterfall automatically. See [Error codes](/guides/uniblock/error-codes) for the full list. # Info API Migration Guide Source: https://docs.uniblock.dev/guides/hyperliquid/info-api/migration Switch from Hyperliquid's public /info API to Uniblock by changing one URL and adding your API key: request and response shapes stay identical. Migrating from Hyperliquid's public `/info` API to Uniblock is a two-line change: point at Uniblock's endpoint and add your API key. Because Uniblock forwards the native `/info` contract verbatim, **every request body and response shape you already use stays the same**. Grab your API key from the [Uniblock dashboard](https://dashboard.uniblock.dev) before you start. ## What changes | | Public Hyperliquid | Uniblock | | ----------------- | ------------------------------------------ | -------------------------------------------------------------- | | **URL** | `https://api.hyperliquid.xyz/info` | `https://api.uniblock.dev/uni/v1/hyperliquid/info?chainId=999` | | **Auth** | none | `x-api-key: YOUR_API_KEY` header | | **Testnet** | `https://api.hyperliquid-testnet.xyz/info` | add `chainId=998` | | **Request body** | unchanged | unchanged | | **Response body** | unchanged | unchanged | | **Rate limits** | request-weight cap per IP | no per-IP cap, but plan-level limits apply | Everything else (the `type` discriminator, operation-specific fields, and the JSON you get back) is identical. ## Before and after ```bash Public /info theme={null} curl --location 'https://api.hyperliquid.xyz/info' \ --header 'Content-Type: application/json' \ --data '{ "type": "clearinghouseState", "user": "0x0000000000000000000000000000000000000000" }' ``` ```bash Uniblock theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/hyperliquid/info?chainId=999' \ --header 'x-api-key: YOUR_API_KEY' \ --header 'Content-Type: application/json' \ --data '{ "type": "clearinghouseState", "user": "0x0000000000000000000000000000000000000000" }' ``` ## Migrate in code If you build requests in application code, change the base URL and inject the header once: ```javascript theme={null} // Before const BASE_URL = "https://api.hyperliquid.xyz/info"; async function info(body) { const res = await fetch(BASE_URL, { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify(body), }); return res.json(); } // After const BASE_URL = "https://api.uniblock.dev/uni/v1/hyperliquid/info?chainId=999"; async function info(body) { const res = await fetch(BASE_URL, { method: "POST", headers: { "Content-Type": "application/json", "x-api-key": process.env.UNIBLOCK_API_KEY, // the only new line }, body: JSON.stringify(body), }); return res.json(); } ``` ```python Python theme={null} import os import requests # Before: "https://api.hyperliquid.xyz/info" BASE_URL = "https://api.uniblock.dev/uni/v1/hyperliquid/info" def info(body): res = requests.post( BASE_URL, params={"chainId": 999}, headers={"x-api-key": os.environ["UNIBLOCK_API_KEY"]}, json=body, ) return res.json() ``` ## After migrating * The public per-IP request-weight cap no longer applies, but **keep your retry/backoff logic**: Uniblock enforces plan-level rate limits and returns `429` when your project exceeds them (backup routing does not bypass this). See [Rate Limits & Caching](/guides/hyperliquid/info-api/limits) and [error codes](/guides/uniblock/error-codes#rate-limits). * Consider Uniblock's synthetic types (`portfolioState`, `batchClearinghouseStates`, `batchPortfolioStates`) to replace multiple round-trips with one request. See the [Info API overview](/guides/hyperliquid/info-api/overview). * Using an off-the-shelf Hyperliquid SDK? See [SDK Compatibility](/guides/hyperliquid/info-api/sdk-compatibility). # Hyperliquid Info API: drop-in /info replacement Source: https://docs.uniblock.dev/guides/hyperliquid/info-api/overview A drop-in replacement for Hyperliquid's public /info REST API: same request and response shapes, no per-IP request-weight cap, automatic provider failover. The Uniblock **Hyperliquid Info API** forwards a native Hyperliquid [`/info`](https://hyperliquid.gitbook.io/hyperliquid-docs/for-developers/api/info-endpoint) request (selected by its `type` field) through Uniblock's unified request lifecycle and returns the upstream response verbatim. It's a drop-in replacement for the public `/info` endpoint: the request and response shapes are identical, but requests flow through the provider waterfall, so you get automatic failover, unified billing, and observability with **no per-IP request-weight cap** (plan-level rate limits still apply). Create your project and grab your API key from the [Uniblock dashboard](https://dashboard.uniblock.dev). ## Endpoint | Method | Path | Description | | ------ | -------------------------- | --------------------------------------------------------------------------- | | `POST` | `/uni/v1/hyperliquid/info` | Forward a native Hyperliquid `/info` request and return the upstream reply. | ### Query parameters * `chainId`: `999` for Hyperliquid mainnet (default) or `998` for Hyperliquid testnet. * `provider`: optionally pin a specific provider; otherwise Uniblock routes through the waterfall. ## How it works Every request body must include a `type` discriminator that mirrors Hyperliquid's own `/info` contract (for example `clearinghouseState`, `l2Book`, `metaAndAssetCtxs`). The `type` selects the operation, and any operation-specific fields are forwarded verbatim. A request without a supported `type` fails fast with a `400` at the HTTP boundary rather than reaching a provider. ### Synthetic Uniblock types Beyond the native Hyperliquid operations, Uniblock defines synthetic `type`s composed on Uniblock's side and dispatched through this same route: | Type | Description | | -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ | | `portfolioState` | Normalized Hyperliquid Portfolio State: a stable account-state view composed across perpetuals, spot balances, and user abstraction. | | `batchClearinghouseStates` | Perpetual clearinghouse state for a list of users in a single request (one Info sub-request per user). | | `batchPortfolioStates` | Full Portfolio State for a list of users in a single request. | Batch types carry a `{ "type": ..., "users": string[] }` body and are limited to **50 users** per request. ## Available types Every Hyperliquid Info `type` supported by at least one unified provider (Alchemy, GoldRush, Dwellir, or Chainstack). Each request body always includes the `type` field; the **Body** column lists the additional fields alongside it. Legend: `*` marks an optional field, and `-` means no fields beyond `type`. Tags: **GoldRush-native** types are served only by GoldRush's verbatim passthrough; provider aliases normalize to a native type before routing; **Uniblock synthetic** types are composed by Uniblock and don't map to a single upstream call. | Type | Body | Returns | | ----------------------------- | ------------------------------------------------------------------ |

Uniblock routes each request to a provider that serves the requested `type`. ## Basic request ```bash cURL theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/hyperliquid/info?chainId=999' \ --header 'x-api-key: YOUR_API_KEY' \ --header 'Content-Type: application/json' \ --data '{ "type": "clearinghouseState", "user": "0x0000000000000000000000000000000000000000" }' ``` ```javascript JavaScript theme={null} const res = await fetch( "https://api.uniblock.dev/uni/v1/hyperliquid/info?chainId=999", { method: "POST", headers: { "x-api-key": "YOUR_API_KEY", "Content-Type": "application/json", }, body: JSON.stringify({ type: "clearinghouseState", user: "0x0000000000000000000000000000000000000000", }), }, ); console.log(await res.json()); ``` ## Next steps Move from the public `/info` API by changing one URL and adding your key. How Uniblock removes the public request-weight cap and how to poll efficiently. Reuse existing Hyperliquid SDKs by overriding the base URL and auth header. The complete Hyperliquid Info endpoint reference in the Unified API section. # SDK Compatibility Source: https://docs.uniblock.dev/guides/hyperliquid/info-api/sdk-compatibility Reuse existing Hyperliquid SDKs against Uniblock's Info API by overriding the base URL and injecting your X-API-Key header, without SDK forks. Because Uniblock forwards the native Hyperliquid `/info` contract verbatim, most existing Hyperliquid SDKs work against Uniblock unchanged: you only override the **base URL** and inject your **API key** header. The request bodies the SDK builds and the responses it parses stay identical. Grab your API key from the [Uniblock dashboard](https://dashboard.uniblock.dev). ## What to override | Setting | Value | | --------------- | -------------------------------------------------- | | Base URL | `https://api.uniblock.dev/uni/v1/hyperliquid/info` | | Query parameter | `chainId=999` (mainnet) or `chainId=998` (testnet) | | Auth header | `x-api-key: YOUR_API_KEY` | If your SDK exposes a configurable base URL and a way to attach default headers, that's all you need. ## Python (`hyperliquid-python-sdk`) The official SDK takes a `base_url` and lets you pass a custom session. Point the base URL at Uniblock and attach your key as a default header: ```python theme={null} import os import requests from hyperliquid.info import Info session = requests.Session() session.headers.update({"x-api-key": os.environ["UNIBLOCK_API_KEY"]}) # The SDK posts to `{base_url}/info`, so use the route prefix as the base. info = Info( base_url="https://api.uniblock.dev/uni/v1/hyperliquid", skip_ws=True, ) info.session = session # reuse the authenticated session state = info.user_state("0x0000000000000000000000000000000000000000") print(state) ``` The SDK appends `/info` to the base URL. Set the base to the `.../uni/v1/hyperliquid` prefix so the final URL resolves to `.../uni/v1/hyperliquid/info`. If your SDK version doesn't send the `chainId` query parameter, Uniblock defaults to `999` (mainnet). ## Raw / custom clients If you built a thin client yourself, override the endpoint and header once and leave every call site unchanged: ```javascript theme={null} const client = { baseUrl: "https://api.uniblock.dev/uni/v1/hyperliquid/info?chainId=999", headers: { "Content-Type": "application/json", "x-api-key": process.env.UNIBLOCK_API_KEY, }, info(body) { return fetch(this.baseUrl, { method: "POST", headers: this.headers, body: JSON.stringify(body), }).then((r) => r.json()); }, }; await client.info({ type: "metaAndAssetCtxs" }); ``` ## Notes & limits * **Synthetic types are Uniblock-only.** `portfolioState`, `batchClearinghouseStates`, and `batchPortfolioStates` aren't part of the public contract, so SDKs won't have typed helpers for them; send them as raw bodies. See the [Info API overview](/guides/hyperliquid/info-api/overview). * **WebSocket transports differ.** SDKs that open a WebSocket to Hyperliquid's public endpoint won't reach Uniblock's stream automatically; set `skip_ws=True` (or the equivalent) and use [Uniblock's WebSockets](/guides/hyperliquid/websockets/overview) for streaming. * **Signing is unaffected.** Uniblock only changes transport and auth; any exchange/signing flow the SDK performs is untouched. # Hyperliquid API Overview Source: https://docs.uniblock.dev/guides/hyperliquid/overview Low-latency Hyperliquid data infrastructure on Uniblock: the Info API, HyperCore WebSockets, and HyperEVM JSON-RPC, all behind one API key. Uniblock gives you complete, low-latency data infrastructure for **Hyperliquid** behind a single API key and billing account. Whether you're building a trading UI, a copy-trade bot, a portfolio tracker, or an on-chain dashboard, you connect to Uniblock instead of stitching together Hyperliquid's public `/info` endpoint, its HyperCore WebSocket, and a HyperEVM node yourself, with automatic provider failover, unified authentication, and no public-API per-IP caps to work around. Every request is authenticated with a project API key. Create your project and grab your key from the [Uniblock dashboard](https://dashboard.uniblock.dev). New to Hyperliquid's architecture? Start with [HyperCore vs. HyperEVM](/guides/quickstart-guides/hypercore-vs-hyperevm). ## What you can build A drop-in replacement for Hyperliquid's public `/info` REST API. Same request and response shapes, routed through Uniblock's provider waterfall: no per-IP request-weight cap, automatic failover. Real-time HyperCore order book and account streams (`l2Book`, `l2BookDiff`, `l4Book`, fills, and liquidations) over one connection, with no per-IP subscription cap. Standard JSON-RPC access to HyperEVM (chain `999`, testnet `998`): read state, send transactions, and call contracts with familiar EVM tooling. ## Why route Hyperliquid through Uniblock * **No per-IP caps.** The public `/info` API caps you at a request-weight budget per IP, and the public WebSocket caps you at 1000 subscriptions per IP. Uniblock lifts both; plan-level rate limits still apply (a `429` on burst; [details](/guides/uniblock/error-codes#rate-limits)). * **One key, one bill.** Info API, WebSockets, and HyperEVM share the same project API key and are metered in compute units. * **Automatic failover.** Requests flow through the unified provider waterfall (Alchemy, Dwellir, Chainstack, GoldRush/Covalent), so a single provider outage doesn't take you down. * **Drop-in migration.** Request and response shapes match Hyperliquid's own contracts, so migrating usually means changing one URL and adding a header. ## The two halves of Hyperliquid Hyperliquid is two components with different jobs, and which offering you use depends on which half you need: | | HyperCore | HyperEVM | | -------------------------------- | ------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------- | | **What it is** | Native trading engine: order book, perps, spot | EVM-compatible smart contract chain | | **How you reach it on Uniblock** | [Info API](/guides/hyperliquid/info-api/overview) (REST) and [WebSockets](/guides/hyperliquid/websockets/overview) | [HyperEVM JSON-RPC](/guides/hyperliquid/evm/overview) | | **Node access** | Controlled by Hyperliquid; you can't run one | Permissionless | See [HyperCore vs. HyperEVM](/guides/quickstart-guides/hypercore-vs-hyperevm) for the full breakdown. ## Get started Three \~5-minute paths: call the Info API, connect a WebSocket, and query HyperEVM over JSON-RPC. # Hyperliquid Quickstart Source: https://docs.uniblock.dev/guides/hyperliquid/quickstart Three short paths to your first Hyperliquid response on Uniblock: the Info REST API, a HyperCore WebSocket stream, and HyperEVM JSON-RPC. Pick the path for what you're building. Each takes about five minutes and assumes you already have an Uniblock project; if not, follow the [Uniblock Quickstart Guide](/guides/getting-started/uniblock-quickstart-guide) first to create one and copy your API key. Every example below authenticates with your project API key. Replace `YOUR_API_KEY` with the key from your [Uniblock dashboard](https://dashboard.uniblock.dev). ## Path 1: Call the Info API Fetch a user's perpetuals clearinghouse state with a single POST. This is Hyperliquid's public `/info` contract, routed through Uniblock. ```bash cURL theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/hyperliquid/info?chainId=999' \ --header 'x-api-key: YOUR_API_KEY' \ --header 'Content-Type: application/json' \ --data '{ "type": "clearinghouseState", "user": "0x0000000000000000000000000000000000000000" }' ``` ```javascript JavaScript theme={null} const res = await fetch( "https://api.uniblock.dev/uni/v1/hyperliquid/info?chainId=999", { method: "POST", headers: { "x-api-key": "YOUR_API_KEY", "Content-Type": "application/json", }, body: JSON.stringify({ type: "clearinghouseState", user: "0x0000000000000000000000000000000000000000", }), }, ); console.log(await res.json()); ``` Change the `type` to any Hyperliquid `/info` operation (`l2Book`, `spotClearinghouseState`, …) or a Uniblock synthetic type like `portfolioState`. Full details in the [Info API overview](/guides/hyperliquid/info-api/overview). ## Path 2: Connect a WebSocket Open one connection and subscribe to per-block order book diffs for a single asset. ```javascript theme={null} import WebSocket from "ws"; const ws = new WebSocket("wss://websocket.uniblock.dev/goldrush", { headers: { "X-API-KEY": "YOUR_API_KEY" }, }); ws.on("open", () => { ws.send( JSON.stringify({ method: "subscribe", subscription: { type: "l2BookDiff", coin: "HYPE" }, }), ); }); ws.on("message", (raw) => console.log(JSON.parse(raw.toString()))); ``` The first message per coin is a full `Snapshot`; the rest are per-block `Updates`. See the [WebSockets overview](/guides/hyperliquid/websockets/overview) for every channel and payload shape. ## Path 3: Query HyperEVM over JSON-RPC Read the latest HyperEVM block number with a standard `eth_blockNumber` call. ```bash cURL theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/json-rpc?chainId=999' \ --header 'x-api-key: YOUR_API_KEY' \ --header 'Content-Type: application/json' \ --data '{ "jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": 1 }' ``` ```javascript JavaScript theme={null} const res = await fetch( "https://api.uniblock.dev/uni/v1/json-rpc?chainId=999", { method: "POST", headers: { "x-api-key": "YOUR_API_KEY", "Content-Type": "application/json", }, body: JSON.stringify({ jsonrpc: "2.0", method: "eth_blockNumber", params: [], id: 1, }), }, ); console.log(await res.json()); ``` Use `chainId=998` for testnet.

Explore all available endpoints and interactive playgrounds # Stream Builder Liquidations Source: https://docs.uniblock.dev/guides/hyperliquid/websockets/builder-liquidations Stream Hyperliquid liquidation fills attributed to your builder code in real time, with builder-fee data and liquidation metadata attached. The `builderLiquidations` channel is a GoldRush-native stream of liquidation fills attributed to a specific **builder code**. Attribution follows the liquidated user's last fill before liquidation: when that fill carried your builder code, the liquidation is emitted on your stream. Think of it as the intersection of `liquidationFills` and `builderFills`: you only receive liquidations attributed to your builder address, with the `builder` and `liquidation` metadata populated on every entry. Use it to monitor liquidations across your builder's order flow without filtering the global stream yourself. `builderLiquidations` requires a `builder` address; there's no wildcard subscription. It's billed at **1 credit/min** (5,000 CU/min), the same rate as the other account streams. See [pricing](/guides/hyperliquid/websockets/overview#pricing). ## Subscribe ```json theme={null} { "method": "subscribe", "subscription": { "type": "builderLiquidations", "builder": "0xb84168cf3be63c6b8dad05ff5d755e97432ff80b" } } ``` | Field | Required | Meaning | | ----------------- | -------- | ----------------------------------------------------------------------------------------- | | `builder` | Yes | Builder address whose routed liquidation fills you want, as lowercase `0x`-prefixed hex. | | `aggregateByTime` | No | Merge partial fills from the same liquidation within the same block. Defaults to `false`. | | `dex` | No | Filter to a single DEX; omit to receive fills from all DEXs. | A missing or malformed `builder` field returns an error message on the `error` channel: ```json theme={null} { "channel": "error", "data": "subscription builderLiquidations requires a 'builder' field" } ``` ## Message format Unlike the other channels on this connection, `builderLiquidations` messages keep the upstream wire shape and are **not** wrapped in the `channel`/`data` envelope: match on `msg.type === "builderLiquidations"` rather than `msg.channel`. Each message carries an array of `[address, fill]` tuples, where the address is the **liquidated wallet** and the fill is the liquidation attributed to your builder: ```json theme={null} { "type": "builderLiquidations", "liquidations": [ [ "0x742d35cc6634c0532925a3b844bc9e7595f7f2e2", { "coin": "ETH", "px": "2150.50", "sz": "1.5", "side": "A", "time": 1704067200000, "startPosition": "1.5", "dir": "Close Long", "closedPnl": "-125.50", "hash": "0xabc...def", "oid": 12345678, "crossed": true, "fee": "2.50", "tid": 87654321, "cloid": null, "feeToken": "USDC", "builder": "0xb84168cf3be63c6b8dad05ff5d755e97432ff80b", "builderFee": null, "deployerFee": null, "twapId": null, "liquidation": { "liquidatedUser": "0x742d35cc6634c0532925a3b844bc9e7595f7f2e2", "markPx": "2148.00", "method": "market" }, "user": "0x742d35cc6634c0532925a3b844bc9e7595f7f2e2" } ] ] } ``` Fills follow the standard Hyperliquid fill shape (`coin`, `px`, `sz`, `side`, `time`, `dir`, `closedPnl`, and so on), extended with the fields that make this stream useful: | Field | Meaning | | ---------------------------- | ---------------------------------------------------------------------- | | `builder` | The builder code that routed the closing order. | | `builderFee` | Builder fee earned on the fill, in `feeToken`; `null` if none. | | `deployerFee` | Deployer fee attributed to the fill; `null` if none. | | `liquidation.liquidatedUser` | The wallet that was liquidated (mirrors the tuple address and `user`). | | `liquidation.markPx` | Mark price at liquidation time. | | `liquidation.method` | How the position was closed: `"market"` or `"backstop"`. | TWAP fills don't carry builder codes. If a user's last fill before liquidation was a TWAP fill, no builder liquidation is emitted for it. ## When to use builder liquidations Monitoring liquidations across your builder's order flow: alerting your users when their positions are force-closed, or auditing liquidation outcomes per DEX. You want every liquidation on the venue regardless of builder attribution; the global stream costs the same and needs no `builder` address. ## Pair with other streams `builderLiquidations` tells you which of your builder's positions were force-closed; the surrounding channels fill in the rest: * `builderFills`: every fill attributed to your builder, not just liquidations. * `liquidationFills`: the global liquidation stream across all builders. * `userFills` / `orderUpdates`: per-wallet fills and order lifecycle events. See the full list in the [WebSocket overview](/guides/hyperliquid/websockets/overview#available-channels). # Connect & Migrate Source: https://docs.uniblock.dev/guides/hyperliquid/websockets/connect Open your first Uniblock Hyperliquid WebSocket connection, authenticate with X-API-KEY, and migrate from the public HyperCore WebSocket by changing one URL. This guide walks through opening a connection, subscribing, and (if you're already on Hyperliquid's public WebSocket) migrating with a one-line change. Grab your API key from the [Uniblock dashboard](https://dashboard.uniblock.dev). ## 1. Connect Open a WebSocket to Uniblock's endpoint and authenticate with the `X-API-KEY` header (recommended) or an `apiKey` query parameter. ```javascript theme={null} import WebSocket from "ws"; const ws = new WebSocket("wss://websocket.uniblock.dev/goldrush", { headers: { "X-API-KEY": "YOUR_API_KEY" }, }); ws.on("open", () => console.log("Connected to Hyperliquid via Uniblock")); ``` Confirm your credentials before opening a stream: `curl 'https://websocket.uniblock.dev/goldrush/validate' --header 'X-API-KEY: YOUR_API_KEY'` ## 2. Subscribe Send a `subscribe` message once the connection is open: ```javascript theme={null} ws.on("open", () => { ws.send( JSON.stringify({ method: "subscribe", subscription: { type: "l2BookDiff", coin: "HYPE" }, }), ); }); ws.on("message", (raw) => console.log(JSON.parse(raw.toString()))); ``` See the [WebSocket overview](/guides/hyperliquid/websockets/overview) for every channel and its payload shape. ## Migrate from the public WebSocket Switching from Hyperliquid's public HyperCore WebSocket is a one-line change: the subscribe/unsubscribe message format is the same. | | Public Hyperliquid | Uniblock | | -------------------- | ------------------------------ | --------------------------------------- | | **URL** | `wss://api.hyperliquid.xyz/ws` | `wss://websocket.uniblock.dev/goldrush` | | **Auth** | none | `X-API-KEY` header or `apiKey` query | | **Subscription cap** | 1000 per IP | none | | **Message format** | unchanged | unchanged | ```javascript theme={null} // Before const ws = new WebSocket("wss://api.hyperliquid.xyz/ws"); // After const ws = new WebSocket("wss://websocket.uniblock.dev/goldrush", { headers: { "X-API-KEY": process.env.UNIBLOCK_API_KEY }, }); ``` Uniblock adds GoldRush-native channels the public feed doesn't have: `l2BookDiff`, `l4Book`, and `liquidationFills`. Once migrated you can drop any logic that worked around the 1000-subscription cap. ## 3. Keep the connection healthy * **Keep-alive:** send a ping every 30–60 seconds to avoid idle timeouts. * **Reconnect with backoff:** on disconnect, re-open and re-send every subscription using exponential backoff. On reconnect, discard local order book state and re-seed from the fresh snapshots rather than replaying missed updates. * **Scope subscriptions:** subscribe per `coin` rather than the wildcard stream when you only need a few assets; wildcard is billed at a much higher rate. ## Next steps # Build with the L2 Order Book Source: https://docs.uniblock.dev/guides/hyperliquid/websockets/l2-book Stream self-contained Hyperliquid HyperCore L2 order book snapshots via the l2Book channel for top-of-book quotes, spread monitoring, and depth analytics. The `l2Book` channel streams real-time **L2 order book** data: bids and asks aggregated into price levels by significant figures. Each message is self-contained, so it's the simplest channel to consume: you don't maintain local state between messages. Use it for top-of-book quotes, spread monitoring, and depth analytics. For high-frequency book tracking across many assets, prefer [`l2BookDiff`](/guides/hyperliquid/websockets/l2-book-diff); it sends only changed levels and is billed at a fraction of the per-minute rate. ## Subscribe ```json theme={null} { "method": "subscribe", "subscription": { "type": "l2Book", "coin": "HYPE" } } ``` `coin` is optional; omit it to stream **all** assets on one subscription (billed at the higher wildcard rate; see [pricing](/guides/hyperliquid/websockets/overview#pricing)). ## Message shape Each message carries the aggregated book for a coin. Levels are a two-element array (`[bids, asks]`), and each level is `{ px, sz, n }`. ```json theme={null} { "channel": "l2Book", "data": { "coin": "HYPE", "levels": [ [{ "px": "0.50", "sz": "100", "n": 5 }, { "px": "0.49", "sz": "250", "n": 8 }], [{ "px": "0.51", "sz": "200", "n": 3 }, { "px": "0.52", "sz": "120", "n": 4 }] ] } } ``` | Field | Meaning | | -------- | -------------------------------------------- | | `px` | Price level, as a string. | | `sz` | Total size resting at that level. | | `n` | Number of individual orders at that level. | | `levels` | Two-element array: `[bidLevels, askLevels]`. | ## Consume it Because each message is a complete snapshot, you can read top-of-book directly; no state to maintain: ```javascript theme={null} ws.on("message", (raw) => { const msg = JSON.parse(raw.toString()); if (msg.channel !== "l2Book") return; const [bids, asks] = msg.data.levels; const bestBid = bids[0]; // highest bid const bestAsk = asks[0]; // lowest ask const spread = Number(bestAsk.px) - Number(bestBid.px); console.log(`${msg.data.coin} spread: ${spread}`); }); ``` ## When to use L2 vs. L2 diff | Use `l2Book` when… | Use [`l2BookDiff`](/guides/hyperliquid/websockets/l2-book-diff) when… | | -------------------------------------------------- | --------------------------------------------------------------------- | | You want the simplest integration (no local state) | You track the full book at high frequency | | You watch a few assets and care about top-of-book | You subscribe to many assets or the wildcard stream | | Bandwidth and CU cost aren't a concern | You want bandwidth proportional to what changed | # Build with the L2 Order Book Diff Source: https://docs.uniblock.dev/guides/hyperliquid/websockets/l2-book-diff Track live Hyperliquid order book state across many assets with bandwidth proportional to changes: an initial snapshot plus per-block diffs. The `l2BookDiff` channel is a bandwidth-efficient way to track order book changes. Instead of a full book on every update, you get an **initial snapshot** per coin followed by **per-block `Updates`** carrying only the price levels that changed, the same `{ px, sz, n }` structure as [`l2Book`](/guides/hyperliquid/websockets/l2-book). It's a GoldRush-native channel, unavailable on the public Hyperliquid feed, and the cheapest way to keep a live book across many assets. `l2BookDiff` is billed at **0.1 credits/min per coin** (500 CU/min): a fifth of `l2Book`. See [pricing](/guides/hyperliquid/websockets/overview#pricing). ## Subscribe ```json theme={null} { "method": "subscribe", "subscription": { "type": "l2BookDiff", "coin": "HYPE" } } ``` `coin` accepts: * a single asset: `"HYPE"` * an array: `["HYPE", "BTC", "ETH"]` * omitted entirely: streams all perps on one connection. When omitted, specify `marketTypes` like `["spot"]` or `["*"]` for multi-market coverage. ## Payload shapes The first message per coin is a `Snapshot`; subsequent messages are `Updates`. ### Snapshot ```json theme={null} { "channel": "l2BookDiff", "data": { "Snapshot": { "coin": "HYPE", "levels": [ [{ "px": "0.50", "sz": "100", "n": 5 }], [{ "px": "0.51", "sz": "200", "n": 3 }] ] } } } ``` `levels` is `[bids, asks]`; each entry is a price object. ### Update ```json theme={null} { "channel": "l2BookDiff", "data": { "Updates": { "book_diffs": [ { "coin": "HYPE", "levels": [ [{ "px": "0.50", "sz": "50", "n": 4 }], [{ "px": "0.51", "sz": "0", "n": 0 }] ] } ] } } } ``` | Field | Meaning | | ------------ | ----------------------------------------------------- | | `px` | Price level, as a string. | | `sz` | Size at that level; `"0"` means **delete** the level. | | `n` | Number of individual orders at the level. | | `coin` | Asset symbol (e.g. `HYPE`, `BTC`). | | `levels` | Two-element array: `[bidLevels, askLevels]`. | | `book_diffs` | Array of diff objects, one per affected coin. | ## Maintain a local book 1. On `Snapshot`: initialize (or reset) the coin's book with bid and ask maps. 2. On `Updates`: for each `book_diff`, apply the changed levels to the matching side. 3. When `sz === "0"`, delete that price level; otherwise set or update it. ```typescript theme={null} type Level = { px: string; sz: string; n: number }; function applyLevels(side: Map, levels: Level[]) { for (const lvl of levels) { if (lvl.sz === "0") side.delete(lvl.px); else side.set(lvl.px, lvl); } } const books = new Map; asks: Map }>(); ws.on("message", (raw) => { const msg = JSON.parse(raw.toString()); if (msg.channel !== "l2BookDiff") return; if (msg.data.Snapshot) { const { coin, levels } = msg.data.Snapshot; const book = { bids: new Map(), asks: new Map() }; applyLevels(book.bids, levels[0]); applyLevels(book.asks, levels[1]); books.set(coin, book); } else if (msg.data.Updates) { for (const diff of msg.data.Updates.book_diffs) { const book = books.get(diff.coin); if (!book) continue; // wait for the snapshot first applyLevels(book.bids, diff.levels[0]); applyLevels(book.asks, diff.levels[1]); } } }); ``` Reconstruct top-of-book by scanning your local maps for the highest bid and lowest ask. ## Reconnection On reconnect, resend your original subscription. Fresh snapshots arrive first: **discard local state for affected coins and re-seed from those snapshots** rather than attempting to replay missed updates. # Build with the L4 Order Book Source: https://docs.uniblock.dev/guides/hyperliquid/websockets/l4-book Get per-order Hyperliquid book data (individual orders with user, order ID, and trigger metadata) for flow attribution and microstructure analysis. The `l4Book` channel is a GoldRush-native, **order-level** book stream. Where L2 aggregates orders into price levels, L4 exposes the **individual orders** that make up each level, with the user, order ID, client order ID, time-in-force, and trigger metadata attached. Use it for per-trader flow attribution, queue-position estimation, and market microstructure analysis. `l4Book` requires a specific `coin`; there's no wildcard subscription. It's billed at **2 credits/min per coin** (10,000 CU/min), and **20 credits/min for `BTC`**. See [pricing](/guides/hyperliquid/websockets/overview#pricing). ## Subscribe ```json theme={null} { "method": "subscribe", "subscription": { "type": "l4Book", "coin": "HYPE" } } ``` Like `l2BookDiff`, you receive an initial **snapshot** of the current resting orders per coin, followed by per-block **updates** containing only the orders that were added, modified, or removed. ## What each order carries Every order in the book exposes the fields that aggregated L2 levels hide: | Field | Meaning | | --------- | ------------------------------------------------------------- | | `user` | Address that placed the order. | | `oid` | Order ID assigned by HyperCore. | | `cloid` | Client order ID, if the placer set one. | | `px` | Limit price, as a string. | | `sz` | Remaining size on the order. | | `side` | `"B"` (bid) or `"A"` (ask). | | `tif` | Time-in-force (e.g. `Gtc`, `Ioc`, `Alo`). | | `trigger` | Trigger metadata for stop / take-profit orders, when present. | Snapshots and updates follow the same `Snapshot` / `Updates` envelope as [`l2BookDiff`](/guides/hyperliquid/websockets/l2-book-diff): apply added and modified orders to a local map keyed by `oid`, and remove orders as they leave the book. ## When to use L4 Attributing flow to specific wallets, estimating queue position, or reconstructing exact order-level microstructure. You only need aggregated depth or top-of-book; [`l2Book`](/guides/hyperliquid/websockets/l2-book) or [`l2BookDiff`](/guides/hyperliquid/websockets/l2-book-diff) are far cheaper. ## Pair with account streams L4 tells you what's resting on the book; the account channels tell you what executes. Combine `l4Book` with: * `allFills`: every fill across the venue. * `liquidationFills`: the global liquidation stream. * `userFills` / `orderUpdates`: per-wallet fills and order lifecycle events. See the full list in the [WebSocket overview](/guides/hyperliquid/websockets/overview#available-channels). # WebSocket API Overview Source: https://docs.uniblock.dev/guides/hyperliquid/websockets/overview Stream Hyperliquid HyperCore order books and account activity in real time over one Uniblock connection, with no per-IP subscription cap. Uniblock's Hyperliquid WebSocket gives you real-time access to **HyperCore** data (the native order book, perpetuals, and account event streams) over a single connection authenticated with your Uniblock API key. Because HyperCore isn't a permissionless chain you can run a node for (see [HyperCore vs. HyperEVM](/guides/quickstart-guides/hypercore-vs-hyperevm)), a WebSocket is the way to get live order book data, and routing through Uniblock lifts the public API's **1000-subscription-per-IP** cap. Streaming is billed in compute units per active subscription per minute. Grab your API key from the [Uniblock dashboard](https://dashboard.uniblock.dev). ## Endpoint ```plaintext theme={null} wss://websocket.uniblock.dev/goldrush ``` A single fixed endpoint; no `chainId` query parameter is required. ## Authentication Two ways to authenticate the connection and validation requests: 1. **Header**: include `X-API-KEY: YOUR_API_KEY` in your request headers (recommended). 2. **URL query parameter**: append `apiKey=YOUR_API_KEY` to the connection string. Header authentication is recommended to avoid exposing your API key in URLs, server logs, or browser history. You can confirm your credentials before opening a stream: ```bash theme={null} curl --location 'https://websocket.uniblock.dev/goldrush/validate' \ --header 'X-API-KEY: YOUR_API_KEY' ``` ## Subscribe and unsubscribe Once connected, send a JSON `subscribe` message. Each message targets a subscription `type`, and most types accept an optional `coin` filter. ```json theme={null} { "method": "subscribe", "subscription": { "type": "l2BookDiff", "coin": "HYPE" } } ``` * `coin` accepts a single asset (`"HYPE"`) or an array (`["HYPE", "BTC"]`). * Omitting `coin` streams **all** assets (wildcard) for the types that support it, billed at a much higher per-minute rate. Stop a stream by sending the matching `unsubscribe` message with the **exact** same subscription body. Billing for that subscription stops as soon as it's removed. ```json theme={null} { "method": "unsubscribe", "subscription": { "type": "l2BookDiff", "coin": "HYPE" } } ``` ## Available channels ### Order book streams | `type` | Description | | ------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | `l2Book` | Real-time L2 order book snapshots and updates: bids and asks aggregated by significant figures. `coin` optional; omit to stream all assets. | | `l2BookDiff` | GoldRush-native: an initial snapshot per coin plus per-block updates carrying only the price/size/count levels that changed. Lighter than `l2Book`. | | `l4Book` | GoldRush-native order-level book: snapshots plus per-block updates exposing user, order ID, client order ID, time-in-force, and trigger metadata. Requires a specific `coin`; no wildcard. | ### Wallet & account activity streams | `type` | Description | | ----------------------------- | -------------------------------------------------------------------------------------------------------- | | `userFills` | Live trade fills for specified wallets, batched per block. | | `orderUpdates` | Order lifecycle events (placements, fills, cancels, rejections) for monitored addresses. | | `liquidationFills` | Global liquidation stream (GoldRush-native). | | `allFills` | Complete global fill stream, with optional single-market filtering. | | `builderFills` | Attributed fills for builder addresses, with builder-fee data. | | `builderLiquidations` | GoldRush-native: liquidation fills routed through a specific builder code. Requires a `builder` address. | | `userNonFundingLedgerUpdates` | Non-funding ledger events such as deposits and withdrawals. | ## Connection & rate limits Unlike the public Hyperliquid WebSocket's 1000-subscription-per-IP cap, Uniblock imposes **no subscription limit**. Wildcard subscriptions default to perpetual markets only; specify `marketTypes` (`["spot"]`, `["*"]`, …) to widen coverage on the types that support it. ## Pricing Streaming bills **credits per minute** for each active subscription, converted to compute units at **5,000 CU per credit**. Charges accrue for as long as a subscription stays open. | Subscription | Credits / min | CU / min | | --------------------------------------------------------------------------------------------------------------------------------- | ------------- | -------- | | `l2Book` (per coin) | 0.5 | 2,500 | | `l2Book` (all assets) | 50 | 250,000 | | `l2BookDiff` (per coin) | 0.1 | 500 | | `l2BookDiff` (all assets) | 10 | 50,000 | | `l4Book` (per coin) | 2 | 10,000 | | `l4Book` (`BTC`) | 20 | 100,000 | | `userFills`, `orderUpdates`, `liquidationFills`, `allFills`, `builderFills`, `builderLiquidations`, `userNonFundingLedgerUpdates` | 1 | 5,000 | ## Best practices * **Security:** use the `X-API-KEY` header where possible to avoid exposing your key. * **Keep-alive:** send a ping every 30–60 seconds to avoid idle timeouts. * **Reconnect with backoff:** on disconnect, re-open and re-send your subscriptions using exponential backoff. * **Scope your subscriptions:** subscribe per `coin` instead of the wildcard stream when you only need a handful of assets; it's dramatically cheaper. ## Build with the order book Self-contained aggregated snapshots: top-of-book quotes and depth analytics. Snapshot plus per-block diffs: track live state with bandwidth proportional to changes. Per-order flow with user, order ID, and trigger metadata for attribution. ## Resources * [Connect & migrate](/guides/hyperliquid/websockets/connect): connect and move off the public WebSocket. * [Stream builder liquidations](/guides/hyperliquid/websockets/builder-liquidations): liquidation fills attributed to your builder code. * [GoldRush provider reference](/reference/websockets/providers/websockets-goldrush): the provider page with the full type list and CU pricing. * [Streaming Hyperliquid with WebSockets](/guides/quickstart-guides/hyperliquid-websocket-guide): end-to-end usage guide. # HyperCore vs. HyperEVM Source: https://docs.uniblock.dev/guides/quickstart-guides/hypercore-vs-hyperevm Understand the difference between HyperCore and HyperEVM, what each component does, and which one you connect to when you integrate with Hyperliquid. Hyperliquid isn't a single chain; it's two components with different jobs. Understanding the split matters before you integrate, because it determines what you can and can't access programmatically. ## HyperCore HyperCore is Hyperliquid's native chain, purpose-built to process trades with very low latency. It runs the on-chain order book, perpetuals, and spot markets that make Hyperliquid a trading venue in the first place. HyperCore is **not** an open, permissionless environment in the way most L1s are. Access to it is fully controlled by Hyperliquid: you can't run your own HyperCore node, and there's no general-purpose smart contract layer to deploy to. It exists to make the exchange fast, not to be a programmable chain third parties build directly on top of. ## HyperEVM HyperEVM is the EVM-compatible chain that bridges Hyperliquid into the broader Ethereum ecosystem. It's what lets developers deploy standard Solidity smart contracts, use familiar EVM tooling, and interact with Hyperliquid using the same JSON-RPC methods you'd use on any other EVM chain. Unlike HyperCore, HyperEVM is the piece you can actually run infrastructure for: nodes are permissionless, and it's the layer meant for third-party integration and contract deployment. ## Key differences | | HyperCore | HyperEVM | | --------------------- | -------------------------------------------------- | ----------------------------------- | | **Purpose** | Native trading engine (order book, perps, spot) | EVM-compatible smart contract chain | | **Node access** | Controlled by Hyperliquid (you cannot run a node) | Permissionless (you can run a node) | | **Programmability** | No general-purpose contract layer | Standard EVM smart contracts | | **How you integrate** | Indirectly, via HyperEVM or Hyperliquid's own APIs | Directly, via standard JSON-RPC | ## Which one does Uniblock connect to? Because HyperCore access is controlled by Hyperliquid and isn't open to node operators, Uniblock's JSON-RPC endpoint routes to **HyperEVM**, the chain you can actually query and transact against with standard EVM tooling. See supported networks, chain IDs, and the full JSON-RPC method reference for Hyperliquid on Uniblock. # Streaming Hyperliquid with WebSockets Source: https://docs.uniblock.dev/guides/quickstart-guides/hyperliquid-websocket-guide Consume Hyperliquid HyperCore order book streams in real time through the Uniblock GoldRush WebSocket with one authenticated connection. Hyperliquid's **HyperCore** runs the native order book that powers its perps and spot markets. You can't run a HyperCore node yourself, so the way to get real-time order book data is over a WebSocket. Uniblock exposes this through the **GoldRush** WebSocket: one connection, authenticated with your Uniblock API key, streaming Hyperliquid's [GoldRush HyperCore](https://goldrush.mintlify.app/api-reference/hyperliquid-websocket/l2-book-diff) feed. New to Hyperliquid's architecture? Read [HyperCore vs. HyperEVM](/guides/quickstart-guides/hypercore-vs-hyperevm) first, since this guide covers the HyperCore side (order book data), not the EVM JSON-RPC side. ## 1. Connect Open a WebSocket to Uniblock's GoldRush endpoint. Authenticate with the `X-API-KEY` header (recommended) or an `apiKey` query parameter. ```javascript theme={null} import WebSocket from "ws"; const ws = new WebSocket("wss://websocket.uniblock.dev/goldrush", { headers: { "X-API-KEY": "YOUR_API_KEY" }, }); ws.on("open", () => { console.log("Connected to Hyperliquid via Uniblock"); }); ``` You can confirm your credentials before opening a stream by calling the validation endpoint: `curl 'https://websocket.uniblock.dev/goldrush/validate' --header 'X-API-KEY: YOUR_API_KEY'` ## 2. Subscribe to the order book Send a `subscribe` message once the connection is open. The example below subscribes to `l2BookDiff` (lightweight per-block order book diffs) for a single asset. ```javascript theme={null} ws.on("open", () => { ws.send( JSON.stringify({ method: "subscribe", subscription: { type: "l2BookDiff", coin: "HYPE" }, }), ); }); ``` * Pass a single asset (`"HYPE"`) or an array (`["HYPE", "BTC"]`) as `coin`. * Omit `coin` to stream **all** assets, but note the wildcard stream is billed at a much higher per-minute rate. ## 3. Handle snapshot and diff messages For `l2BookDiff`, the first message per coin is a full `Snapshot`; subsequent messages are per-block `Updates` containing only the changed levels. ```javascript theme={null} ws.on("message", (raw) => { const msg = JSON.parse(raw.toString()); if (msg.channel !== "l2BookDiff") return; if (msg.data.Snapshot) { const { coin, levels } = msg.data.Snapshot; console.log(`Snapshot for ${coin}`, levels); // [bids, asks] } else if (msg.data.Updates) { for (const diff of msg.data.Updates.book_diffs) { // Each level: { px: price, sz: size, n: order count }. // A level with sz === "0" means that price level was removed. console.log(`Diff for ${diff.coin}`, diff.levels); } } }); ``` Apply each diff on top of your local copy of the book: replace the level at `px` with the new `sz`/`n`, and delete the level when `sz` is `"0"`. ## 4. Unsubscribe Stop a stream by sending an `unsubscribe` message with the **exact** same subscription body you subscribed with. Billing for that subscription stops as soon as it's removed. ```javascript theme={null} ws.send( JSON.stringify({ method: "unsubscribe", subscription: { type: "l2BookDiff", coin: "HYPE" }, }), ); ``` ## Other subscription types `l2BookDiff` is one of several HyperCore streams available on the same connection. Swap the `type` (and, for account streams, follow GoldRush's per-type payload) to subscribe to: * `l2Book`: full L2 order book snapshots and updates. * `l4Book`: full per-order (L4) book. * `userFills`, `orderUpdates`, `liquidationFills`, `allFills`, `builderFills`, `builderLiquidations`, `userNonFundingLedgerUpdates`: account and venue event streams. See the [GoldRush provider reference](/reference/websockets/providers/websockets-goldrush) for the full type list and per-subscription CU pricing. ## Best practices * **Keep-alive:** send a ping every 30–60 seconds to avoid idle timeouts. * **Reconnect with backoff:** on disconnect, re-open and re-send your subscriptions using exponential backoff. * **Scope your subscriptions:** subscribe per `coin` instead of the wildcard stream when you only need a handful of assets; it's dramatically cheaper. ## Resources * [GoldRush provider reference](/reference/websockets/providers/websockets-goldrush) * [GoldRush Hyperliquid WebSocket docs](https://goldrush.mintlify.app/api-reference/hyperliquid-websocket/l2-book-diff) * [HyperCore vs. HyperEVM](/guides/quickstart-guides/hypercore-vs-hyperevm) # Authenticate Uniblock API requests with your API key Source: https://docs.uniblock.dev/guides/uniblock/authentication Authenticate requests to the Uniblock Unified API by adding your project API key in the X-API-Key header from cURL, JavaScript, Python, and more. # How to authenticate your Uniblock API key Every request to the Uniblock API must include your project API key in the request header. The key identifies your project, tracks usage, and gates access to the endpoints your plan supports. ## Steps 1. **Obtain your API key:** Navigate to your [Uniblock dashboard](https://dashboard.uniblock.dev), open your project, and copy the API key shown on the Overview page. 2. **Include the key in every request:** Add an `X-API-Key` header to each HTTP request you make to the Uniblock API. ```bash cURL theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/nft/balance?chainId=1&walletAddress=0x...' \ --header 'X-API-Key: YOUR_UNIBLOCK_API_KEY' ``` ```javascript JavaScript theme={null} const options = { method: 'GET', headers: { accept: 'application/json', 'X-API-Key': 'YOUR_UNIBLOCK_API_KEY' } }; fetch('https://api.uniblock.dev/uni/v1/nft/balance?chainId=1&walletAddress=0x...', options) .then(res => res.json()) .then(console.log); ``` 3. **Test in the API Tester:** Open the [Uniblock Explorer](https://explorer.uniblock.dev), click **Authorize**, paste your API key, and click **Authorize** again. Every endpoint in the explorer will now send requests authenticated as your project. 4. **Start calling endpoints:** With your key in place, you're ready to call any Unified API endpoint your plan supports. Usage and analytics for all authenticated calls appear in your project dashboard under **Endpoints → Analytics**. If you switch projects in the dashboard, update the API key in your code to match the new project, since each project has its own key and its own usage metrics. ## Header-only authentication for HTTP endpoints Uniblock HTTP endpoints accept the API key only in the `X-API-Key` header. This applies to the Unified API, the Unified JSON-RPC endpoint (`https://api.uniblock.dev/uni/v1/json-rpc`), and Direct API endpoints. There is no URL format that embeds the API key in the path or as a query parameter. If you are migrating from a provider that uses key-in-URL endpoints, keep the URL key-free and move the key into the `X-API-Key` header: ```bash theme={null} # Not supported: key embedded in the URL # https://api.uniblock.dev/uni/v1/json-rpc/YOUR_UNIBLOCK_API_KEY # Supported: key in the X-API-Key header curl --request POST \ --url 'https://api.uniblock.dev/uni/v1/json-rpc?chainId=1' \ --header 'Content-Type: application/json' \ --header 'X-API-Key: YOUR_UNIBLOCK_API_KEY' \ --data '{"jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": 1}' ``` WebSocket connections are the exception. Most WebSocket endpoints also use the `X-API-KEY` header, but some provider-specific endpoints accept an `apiKey` query parameter instead. See [Authenticating Uniblock WebSocket connections](/reference/websockets/authentication). # Auto-routing Source: https://docs.uniblock.dev/guides/uniblock/autorouting/uniblock-auto-routing Uniblock auto-routing directs each API call to the best blockchain data provider on reliability, cost, and performance with automatic failover. ## What is auto-routing? Auto-routing automatically directs your API calls to the best available blockchain data provider based on reliability, cost, and performance. Instead of managing multiple provider keys and handling failovers manually, Uniblock routes requests intelligently and switches providers seamlessly when issues occur. **Use auto-routing when you need:** * Guaranteed uptime with automatic failover * Cost-optimized provider selection * Multi-provider redundancy without manual configuration * Verified data accuracy across providers Auto-routing is enabled by default for all Uniblock API keys. No setup required. *** ## Quick example See auto-routing in action with a simple API call: ```bash Standard API call with auto-routing theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/token/balances?chainId=1&address=0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb' \ --header 'x-api-key: YOUR_API_KEY' ``` **Behind the scenes, Uniblock:** 1. Routes to the optimal provider (e.g., Alchemy) 2. If Alchemy fails, retries 3 times 3. If still failing, switches to backup (e.g., Infura) 4. Returns the response seamlessly **You don't need to change anything in your code.** Auto-routing handles all provider management automatically. *** ## How it works When you make an API call with your Uniblock key: 1. **Route selection** - Uniblock evaluates available providers for cost and reliability 2. **Primary request** - Your call is routed to the optimal provider 3. **Auto-retry** - If the call fails, it's automatically retried with the same provider 4. **Failover** - After max retries, the request routes to the next best provider 5. **Data verification** - (Pro+ plans) Response data is verified across multiple providers *** ## Core features ### Default routing Access all Uniblock-integrated providers with a single API key. No provider selection or configuration required. **Available on:** All plans (including free) **Key benefits:** * Instant access to 55+ blockchain data providers * Pre-configured backup provider list * Works immediately with free tier [Learn more about default routing →](/guides/uniblock/autorouting/uniblock-default-routing) ### Backup providers Automatic failover to backup providers when the primary provider is unavailable or rate-limited. **Available on:** All plans (including free) **Key benefits:** * Zero downtime during provider outages * Seamless failover without code changes * Configurable priority list for custom routing **Example scenario:** Your app makes 1,000 requests/minute. Your primary provider (Alchemy) hits rate limits at request #500. Auto-routing automatically switches to your backup provider (Infura) for requests #501-1000 without dropping a single call. [Learn more about backup providers →](/guides/uniblock/autorouting/uniblock-backup) ### Data consensus Available on Pro plans and above Verifies response data across multiple providers to ensure accuracy. **Key benefits:** * Eliminates incorrect data from single-provider errors * Detects and filters outlier responses * Ensures data consistency for critical operations **Example scenario:** Your app requests the current ETH price. Data consensus queries 3 providers: * Provider A: \$2,500.00 * Provider B: \$2,501.50 * Provider C: \$25,000.00 (outlier) The system detects Provider C's outlier and returns the consensus value of \~\$2,500, preventing a critical pricing error. [Learn more about data consensus →](/guides/uniblock/autorouting/uniblock-data-consensus) *** ## Common use cases Ensure 99.99% uptime with automatic failover across multiple providers. Automatically route to the cheapest provider without sacrificing reliability. Seamlessly switch providers when rate limits are hit. Verify critical data across multiple sources with data consensus. *** ## Next steps Learn how default routing works and try it without an API key. Configure custom failover lists for maximum reliability. Optimize for cost and performance automatically. Verify data accuracy across multiple providers. *** ## Common pitfalls **Free tier limitations** - Default routing on the free tier has rate limits suitable for testing only. Upgrade to Growth or higher for production use. **Data consensus latency** - Data consensus adds \~100-200ms latency as it queries multiple providers. Only enable for critical data where accuracy is paramount. **Retry latency** - Auto-retry adds latency to failed requests (1-7 seconds depending on configuration). Factor this into timeout settings. *** Create your free account and start building with unified blockchain infrastructure across 300+ chains. Explore all available endpoints and interactive playgrounds # Backup providers Source: https://docs.uniblock.dev/guides/uniblock/autorouting/uniblock-backup Configure backup providers in Uniblock so requests automatically fail over when your primary provider is down, rate-limited, or returning errors. ## What are backup providers? Backup providers help prevent failures caused by a single provider issue. When your primary provider is unavailable, hits a provider-specific rate limit, or returns errors, Uniblock automatically routes requests to backup providers in your configured priority list. If you receive a `429` from Uniblock itself, that means your project has reached the request limit available under your current Uniblock plan. In that case, backup providers do not override the plan-level limit. **Use backup providers when you need:** * 99.99%+ uptime guarantees * Protection against provider outages * Automatic provider failover when an upstream provider is rate-limited * Zero-downtime failover Backup providers are enabled by default for all Uniblock users. No configuration required. *** ## How it works Uniblock maintains a priority list (fallback list) of providers for each endpoint category. When a request fails: 1. **Primary attempt** - Request goes to your top-priority provider 2. **Failure detection** - System detects failure (timeout, rate limit, 5xx error, invalid key) 3. **Automatic failover** - Request immediately routes to next provider in list 4. **Seamless response** - Your application receives the response without knowing a failover occurred Backup providers handle upstream provider failures and provider-specific rate limits. Uniblock plan limits still apply separately, and a `429` response from Uniblock means your project has exceeded the request rate included with your current plan. *** ## Fallback list types ### Internal fallback (default) Uniblock's pre-configured provider list optimized for reliability and cost. **Characteristics:** * No setup required * Enabled by default for all users * Optimized based on real-time provider performance * Includes 55+ blockchain data providers * Automatically updated as provider performance changes **Example internal fallback list for token balances:** 1. Covalent (lowest cost, high reliability) 2. Moralis (medium cost, high reliability) 3. Alchemy (higher cost, highest reliability) 4. QuickNode (backup) ```bash Using internal fallback (default) theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/token/balances?chainId=1&address=0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb' \ --header 'x-api-key: YOUR_API_KEY' ``` If Covalent fails → automatically tries Moralis → then Alchemy → then QuickNode. ### External keys fallback (custom) Bring your own provider API keys and configure custom priority lists. **Characteristics:** * Use your existing provider credits * Full control over provider priority * Uniblock auto-routing as final fallback * Configure different lists per endpoint category **Example custom fallback list:** 1. Your Alchemy key (primary) 2. Your Infura key (backup) 3. Your QuickNode key (backup) 4. Uniblock auto-routing (final fallback) **Benefits of this approach:** * Consume your own provider credits first * Uniblock provides ultimate reliability as final backup * Custom routing based on your provider relationships * Unified management of all provider keys [Learn how to configure custom fallback lists →](/guides/uniblock/autorouting/dashboard-integrations) *** ## Common failure scenarios ### Upstream provider rate limit exceeded **Scenario:** Your Alchemy key hits its own provider rate limit (300 requests/second). **What happens:** 1. Request #301 fails with rate limit error 2. Uniblock detects rate limit response 3. Request automatically routes to Infura (next in list) 4. Your app receives successful response **Result:** Zero downtime, seamless failover for that provider-specific limit. This is different from a Uniblock `429`. A Uniblock `429` means your project has reached the request limit included with your current plan, not that a backup provider should be tried. ### Provider outage **Scenario:** Infura experiences a service outage. **What happens:** 1. Request times out after 5 seconds 2. Uniblock detects timeout 3. Request automatically routes to QuickNode 4. Your app receives successful response **Result:** Your users never notice the outage. ### Invalid API key **Scenario:** Your provider API key expires or is invalid. **What happens:** 1. Request fails with 401 authentication error 2. Uniblock detects invalid key 3. Request automatically routes to next provider 4. Dashboard alerts you to update the key **Result:** Service continues while you fix the key. ### Provider-specific error **Scenario:** Provider returns 5xx server error. **What happens:** 1. Request fails with 500 internal server error 2. Uniblock detects server error 3. Request automatically routes to next provider 4. Your app receives successful response **Result:** Provider issues don't affect your application. *** ## Configuration example Here's how a custom fallback list works with your own provider keys: In the [Uniblock dashboard](https://dashboard.uniblock.dev), add your provider API keys: * Alchemy: `alch_abc123...` * Infura: `infura_xyz789...` * QuickNode: `qn_def456...` Set your fallback order for token endpoints: 1. Alchemy (your key) 2. Infura (your key) 3. QuickNode (your key) 4. Uniblock auto-routing (final backup) ```bash theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/token/balances?chainId=1&address=0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb' \ --header 'x-api-key: YOUR_UNIBLOCK_KEY' ``` If Alchemy fails, Uniblock automatically tries Infura, then QuickNode, then its own provider pool. Your code never changes. *** ## Key benefits Achieve 99.99%+ uptime with multi-provider redundancy. Automatic provider switching transparent to your application. Reduce provider-specific rate limit failures by automatically switching to backup providers. Use cheaper providers first, expensive ones as backup. *** ## Monitoring and alerts Track failover events in the Uniblock dashboard: * **Failover count** - How many times backup providers were used * **Provider health** - Real-time status of each provider * **Error breakdown** - Types of failures triggering failovers * **Cost analysis** - Which providers are being used most **Alerts available:** * Provider key expiration warnings * High failover rate notifications * Provider performance degradation alerts *** ## Best practices **Use Uniblock auto-routing as final fallback** - Even with your own provider keys, add Uniblock auto-routing as the last item in your priority list for ultimate reliability. **Configure different lists per endpoint category** - Token endpoints may need different providers than NFT endpoints. Optimize each category separately. **Monitor failover rates** - High failover rates indicate issues with your primary provider. Review and adjust your priority list. **Test your fallback configuration** - Temporarily disable your primary provider to verify failover works as expected. *** ## Next steps Set up custom fallback lists with your own provider keys. Learn how auto-retry works before failover occurs. Optimize provider selection for cost and performance. Monitor provider health and failover events. *** ## Common pitfalls **Don't rely on a single provider** - Even with backup providers, test your configuration to ensure failover works correctly. **Provider key expiration** - Set up alerts for expiring provider keys. Expired keys trigger unnecessary failovers. **Inconsistent data across providers** - Different providers may return slightly different data formats. Test thoroughly when switching providers. **Cost implications** - Backup providers may have different pricing. Monitor which providers are being used to manage costs effectively. *** Create your free account and start building with unified blockchain infrastructure across 300+ chains.

Data consensus verifies API response data by querying multiple blockchain providers and comparing their responses. This ensures the data you receive is accurate, consistent, and free from provider-specific errors or anomalies. **Use data consensus when you need:** * Guaranteed data accuracy for critical operations * Protection against provider data errors * Verification of financial data (prices, balances) * Confidence in high-stakes transactions Data consensus is automatically enabled for all Uniblock users. *** ## How it works When data consensus is enabled, Uniblock follows this process: 1. **Primary request** - Query your primary provider 2. **Parallel verification** - Simultaneously query 2-3 additional providers 3. **Compare responses** - Analyze data from all providers 4. **Detect outliers** - Identify responses that deviate significantly 5. **Return consensus** - Provide verified data based on majority agreement *** ## Why data consensus matters ### Without data consensus A single provider error can cause critical issues: ```json Provider returns incorrect price theme={null} { "tokenAddress": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", "symbol": "USDC", "price": 25.0 // WRONG: should be $1.00 } ``` **Consequences:** * Incorrect portfolio valuations * Failed trading decisions * User trust issues * Financial losses ### With data consensus Errors are detected and filtered: ``` Provider A: $1.00 Provider B: $1.01 Provider C: $25.00 (outlier detected) Consensus result: $1.00 ``` **Benefits:** * Accurate data guaranteed * Outliers automatically filtered * Confidence in critical operations * Protection against provider bugs *** ## Supported endpoints Data consensus works with these endpoint categories: ### Token endpoints * Token prices * Token balances * Token transfers * Token allowances ### NFT endpoints * NFT floor prices * NFT metadata * NFT ownership * Collection stats ### Transaction endpoints * Transaction receipts * Gas prices * Block data ### Market data endpoints * Token prices * Trading volume * Market cap Data consensus is not available for JSON-RPC endpoints or provider-specific features. *** ## Performance impact Data consensus adds latency as it queries multiple providers: | Providers queried | Added latency | Use case | | ----------------- | ------------- | --------------------- | | **2 providers** | \~50-100ms | Low-latency needs | | **3 providers** | \~100-200ms | Standard verification | | **4 providers** | \~150-300ms | Maximum accuracy | **Optimization tips:** * Enable only for critical endpoints * Use lower provider counts for time-sensitive operations * Cache consensus results when appropriate * Disable for non-critical data *** ## Key benefits Cross-verify data across multiple sources for guaranteed accuracy. Automatically detect and filter provider errors and anomalies. Minimize impact of incorrect data on critical operations. Make decisions based on verified, consensus-based data. *** ## When to use data consensus ### Use data consensus for: * **Token prices** - Critical for trading, swaps, portfolio valuation * **Token balances** - Important for transaction validation * **NFT floor prices** - Essential for marketplace accuracy * **Gas prices** - Affects transaction cost calculations * **Financial calculations** - Any data affecting money *** ## Next steps Learn how auto-retry works with data consensus. Configure provider fallback lists for consensus queries. Optimize provider selection for consensus queries. Configure consensus settings and monitor metrics. *** ## Common pitfalls **Using for all endpoints** - Data consensus adds latency and cost. Only enable for critical data. **Too strict thresholds** - Overly strict outlier detection may flag valid variations. Use moderate settings. **Ignoring outlier patterns** - Frequent outliers from one provider indicate reliability issues. Investigate and adjust. **Not accounting for latency** - Consensus adds 100-300ms. Factor this into timeout and UX design. *** Create your free account and start building with unified blockchain infrastructure across 300+ chains. Explore all available endpoints and interactive playgrounds # Data normalization Source: https://docs.uniblock.dev/guides/uniblock/autorouting/uniblock-data-normalization Uniblock data normalization converts provider-specific responses into a consistent unified schema so you can switch providers without changing code. ## What is data normalization? Data normalization automatically converts provider-specific response formats into a consistent, unified schema. This eliminates the need to write provider-specific parsing logic or handle format variations across different data sources. **Use data normalization when you need:** * Consistent data formats regardless of provider * Zero provider-specific parsing logic * Seamless provider switching without code changes * Predictable data structures across all endpoints Data normalization is enabled by default for all Uniblock users. All responses follow the same schema regardless of underlying provider. *** ## How it works Different providers return blockchain data in different formats. Uniblock normalizes all responses into a consistent schema: 1. **Provider response** - Raw data received from blockchain provider 2. **Schema mapping** - Uniblock maps provider fields to unified schema 3. **Type conversion** - Converts data types (string/number/formatted) 4. **Field enrichment** - Adds missing fields with computed values 5. **Unified response** - Returns consistent format to your application **Result:** Your code works with any provider without format-specific logic. *** ## Normalization examples ### Token balances Different providers return token balances in incompatible formats: | Provider | Balance format | Decimals | Formatted value | | ------------ | ----------------------- | ----------------- | ----------------- | | **Alchemy** | `"1000000000"` (string) | Separate field | Not included | | **Moralis** | `1000000000` (number) | Separate field | Not included | | **Covalent** | `"1000.00"` (formatted) | Included in value | Already formatted | **Uniblock normalized response:** ```json theme={null} { "balance": "1000000000", "decimals": 6, "balanceFormatted": "1000.00" } ``` **Result:** All three formats unified into single, predictable structure. ### Transaction timestamps Providers use different timestamp formats: | Provider | Timestamp format | Example | | ------------ | ----------------------------- | ------------------------ | | **Alchemy** | Unix timestamp (seconds) | `1640995200` | | **Moralis** | ISO 8601 string | `"2022-01-01T00:00:00Z"` | | **Covalent** | Unix timestamp (milliseconds) | `1640995200000` | **Uniblock normalized response:** ```json theme={null} { "timestamp": 1640995200, "timestampISO": "2022-01-01T00:00:00Z", "blockNumber": 13916166 } ``` **Result:** Both Unix and ISO formats provided for flexibility. ### NFT metadata NFT metadata structures vary significantly across providers: **Alchemy format:** ```json theme={null} { "contract": { "address": "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D" }, "id": { "tokenId": "1" }, "title": "Bored Ape #1", "metadata": { "image": "ipfs://QmRRPWG96cmgTn2qSzjwr2qvfNEuhunv6FNeMFGa9bx6mQ", "attributes": [{ "trait_type": "Background", "value": "Orange" }] } } ``` **Moralis format:** ```json theme={null} { "token_address": "0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d", "token_id": "1", "name": "Bored Ape #1", "image": "ipfs://QmRRPWG96cmgTn2qSzjwr2qvfNEuhunv6FNeMFGa9bx6mQ", "metadata": "{\"attributes\":[{\"trait_type\":\"Background\",\"value\":\"Orange\"}]}" } ``` **Uniblock normalized response:** ```json theme={null} { "contractAddress": "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D", "tokenId": "1", "name": "Bored Ape #1", "description": "The Bored Ape Yacht Club is a collection of 10,000 unique Bored Ape NFTs", "image": "ipfs://QmRRPWG96cmgTn2qSzjwr2qvfNEuhunv6FNeMFGa9bx6mQ", "imageUrl": "https://ipfs.io/ipfs/QmRRPWG96cmgTn2qSzjwr2qvfNEuhunv6FNeMFGa9bx6mQ", "attributes": [ { "traitType": "Background", "value": "Orange" } ] } ``` **Result:** Consistent structure with both IPFS and HTTP URLs, parsed attributes, and camelCase fields. *** ## Real-world scenarios ### Scenario 1: Multi-provider portfolio tracker **Challenge:** Building a portfolio tracker that aggregates data from multiple providers, each with different response formats. **Without normalization:** ```javascript theme={null} // Provider-specific parsing logic required function parseBalance(provider, response) { if (provider === 'alchemy') { return { balance: response.tokenBalance, decimals: response.decimals, formatted: formatBalance(response.tokenBalance, response.decimals), }; } else if (provider === 'moralis') { return { balance: response.balance.toString(), decimals: response.decimals, formatted: formatBalance(response.balance, response.decimals), }; } else if (provider === 'covalent') { return { balance: parseFormattedBalance(response.balance), decimals: extractDecimals(response.balance), formatted: response.balance, }; } } ``` **With Uniblock normalization:** ```javascript theme={null} // Single parsing logic works for all providers const response = await fetch('https://api.uniblock.dev/uni/v1/token/balances', { headers: { 'x-api-key': 'YOUR_API_KEY' }, }); const data = await response.json(); // Always has: balance, decimals, formattedBalance console.log(data.formattedBalance); // Works regardless of provider ``` **Result:** 90% less code, zero provider-specific logic. ### Scenario 2: NFT marketplace integration **Challenge:** Displaying NFT collections from multiple providers with consistent metadata. **Request:** ```bash theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/nft/collection?chainId=1&contractAddress=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D&limit=20' \ --header 'x-api-key: YOUR_API_KEY' ``` **Normalized response:** ```json theme={null} { "nfts": [ { "contractAddress": "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D", "tokenId": "1", "name": "Bored Ape #1", "description": "The Bored Ape Yacht Club...", "image": "ipfs://QmRRPWG96cmgTn2qSzjwr2qvfNEuhunv6FNeMFGa9bx6mQ", "imageUrl": "https://ipfs.io/ipfs/QmRRPWG96cmgTn2qSzjwr2qvfNEuhunv6FNeMFGa9bx6mQ", "owner": "0x789...", "attributes": [ { "traitType": "Background", "value": "Orange" }, { "traitType": "Eyes", "value": "Bored" } ] } ] } ``` **Result:** Consistent NFT structure with resolved IPFS URLs and parsed attributes. *** ## Normalized field types Uniblock ensures consistent data types across all providers: ### Address fields **Always returned as:** * Checksummed Ethereum addresses * Lowercase for consistency in comparisons * Validated format ```json theme={null} { "address": "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb", "contractAddress": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48" } ``` ### Numeric values **Always returned as:** * String for large numbers (prevents precision loss) * Formatted decimal version included * Original decimals preserved ```json theme={null} { "balance": "1000000000000000000", "formattedBalance": "1.0", "decimals": 18 } ``` ### Timestamps **Always returned as:** * Unix timestamp (seconds) * ISO 8601 string * Block number for reference ```json theme={null} { "timestamp": 1640995200, "timestampISO": "2022-01-01T00:00:00Z", "blockNumber": 13916166 } ``` ### Boolean values **Always returned as:** * Native boolean type (not strings) * Consistent naming (isActive, hasMetadata) ```json theme={null} { "isVerified": true, "hasMetadata": false } ``` *** ## Key benefits No provider-specific code needed. Single schema works everywhere. Switch providers without changing your application code. Consistent data types prevent runtime errors and type mismatches. Build faster without handling format variations across providers. *** ## Field mapping reference Common provider field variations and their normalized equivalents: | Data type | Provider variations | Uniblock normalized | | -------------------- | ---------------------------------------------- | ------------------- | | **Token balance** | `tokenBalance`, `balance`, `value` | `balance` | | **Decimals** | `decimals`, `decimal`, `token_decimal` | `decimals` | | **Contract address** | `contract`, `token_address`, `contractAddress` | `contractAddress` | | **Token ID** | `tokenId`, `token_id`, `id.tokenId` | `tokenId` | | **Transaction hash** | `hash`, `tx_hash`, `transactionHash` | `hash` | | **Block number** | `blockNumber`, `block_number`, `block` | `blockNumber` | | **Timestamp** | `timestamp`, `block_timestamp`, `timeStamp` | `timestamp` | | **Gas used** | `gasUsed`, `gas_used`, `gas` | `gasUsed` | | **NFT image** | `image`, `image_url`, `metadata.image` | `image`, `imageUrl` | | **NFT attributes** | `attributes`, `traits`, `metadata.attributes` | `attributes` | *** ## Handling edge cases Uniblock normalization handles common edge cases automatically: ### Null and missing values **Provider behavior:** * Some providers return `null` * Others omit the field entirely * Some return empty strings **Uniblock normalization:** ```json theme={null} { "balance": "0", "balanceFormatted": "0.0", "metadata": null } ``` **Result:** Consistent null handling and default values. ### IPFS URLs **Provider behavior:** * Some return `ipfs://` URIs * Others return gateway URLs * Some return raw CIDs **Uniblock normalization:** ```json theme={null} { "image": "ipfs://QmRRPWG96cmgTn2qSzjwr2qvfNEuhunv6FNeMFGa9bx6mQ", "imageUrl": "https://ipfs.io/ipfs/QmRRPWG96cmgTn2qSzjwr2qvfNEuhunv6FNeMFGa9bx6mQ" } ``` **Result:** Both IPFS URI and HTTP gateway URL provided. ### Large numbers **Provider behavior:** * Some return numbers (lose precision for large values) * Others return strings * Some return scientific notation **Uniblock normalization:** ```json theme={null} { "balance": "1000000000000000000", "balanceFormatted": "1.0", "decimals": 18 } ``` **Result:** String format preserves precision, formatted version for display. ### Case sensitivity **Provider behavior:** * Some use camelCase * Others use snake\_case * Some use PascalCase **Uniblock normalization:** ```json theme={null} { "contractAddress": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", "tokenId": "1", "blockNumber": 13916166 } ``` **Result:** Consistent camelCase across all fields. *** ## Best practices **Use normalized fields directly** - Don't re-parse or transform normalized responses. They're already in optimal format. **Rely on formatted values** - Use `balanceFormatted`, `valueFormatted` for display instead of manual formatting. **Trust type consistency** - Normalized responses have consistent types. No need for type guards or conversions. **Use both timestamp formats** - `timestamp` for calculations, `timestampISO` for display and logging. *** ## Monitoring normalization Track normalization metrics in the [Uniblock dashboard](https://dashboard.uniblock.dev): * **Normalization success rate** - Percentage of responses successfully normalized * **Field mapping coverage** - Which provider fields are being mapped * **Type conversion errors** - Rare cases where normalization fails * **Provider format changes** - Alerts when providers change response formats **Use these metrics to:** * Ensure consistent data quality * Identify provider format changes early * Understand which providers require most normalization * Validate data integrity across providers *** ## Next steps Learn how Uniblock fills data gaps across providers. Verify data accuracy by comparing multiple providers. Explore normalized response schemas for all endpoints. Monitor normalization metrics and data quality. *** ## Common pitfalls **Don't re-parse normalized data** - Normalized responses are already in optimal format. Additional parsing adds complexity and potential errors. **Avoid provider-specific assumptions** - Don't assume data comes from specific provider. Normalization abstracts provider details. **Use string types for large numbers** - JavaScript numbers lose precision for values > 2^53. Always use string `balance` field, not numeric conversions. **Don't mix normalized and raw data** - If using Uniblock, use normalized responses exclusively. Mixing with raw provider data creates inconsistencies. *** Create your free account and start building with unified blockchain infrastructure across 300+ chains.

Data polyfill automatically fills gaps in blockchain data when your primary provider has incomplete coverage. Uniblock detects missing data for specific chains, time periods, or data types and seamlessly retrieves it from alternative providers. **Use data polyfill when you need:** * Complete historical data across all chains * Consistent data availability regardless of provider limitations * Automatic handling of provider-specific gaps * Zero manual provider switching Data polyfill is enabled by default for all Uniblock users. No configuration required. *** ## How it works Uniblock continuously monitors data completeness across providers. When gaps are detected: 1. **Gap detection** - System identifies missing or incomplete data from primary provider 2. **Provider selection** - Automatically selects best alternative provider for the missing data 3. **Data retrieval** - Fetches complete data from backup provider 4. **Unified response** - Returns complete dataset to your application **Result:** You always get complete data without manual provider switching. *** ## Polyfill scenarios ### Missing chain coverage **Scenario:** Provider A has Ethereum data but missing Polygon data. **What happens:** 1. Request for Polygon token balances sent to Provider A 2. Provider A returns no data or error 3. Uniblock detects missing Polygon coverage 4. Request automatically routes to Provider B (has Polygon data) 5. Complete Polygon data returned to your application ```bash Request with automatic chain polyfill theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/token/balances?chainId=137&address=0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb' \ --header 'x-api-key: YOUR_API_KEY' ``` **Result:** Seamless access to Polygon data even when primary provider doesn't support it. ### Historical data gaps **Scenario:** Provider C has recent transactions but missing historical data. **What happens:** 1. Request for transactions from 2020 sent to Provider C 2. Provider C returns only data from 2022 onwards 3. Uniblock detects historical gap (2020-2021) 4. Backfills missing period from Provider D 5. Complete historical dataset returned ```bash Request with automatic historical backfill theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/transactions?chainId=1&address=0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb&startDate=2020-01-01&endDate=2023-12-31' \ --header 'x-api-key: YOUR_API_KEY' ``` **Result:** Complete transaction history without gaps or missing periods. ### Incomplete metadata **Scenario:** Provider E returns incomplete NFT metadata. **What happens:** 1. Request for NFT details sent to Provider E 2. Provider E returns basic data but missing image URLs and attributes 3. Uniblock detects incomplete metadata 4. Enriches response with metadata from Provider F 5. Complete NFT data with all fields returned ```bash Request with automatic metadata enrichment theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/nft/metadata?chainId=1&contractAddress=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D&tokenId=1' \ --header 'x-api-key: YOUR_API_KEY' ``` **Response with polyfilled metadata:** ```json theme={null} { "tokenId": "1", "name": "Bored Ape #1", "description": "The Bored Ape Yacht Club...", "image": "ipfs://QmRRPWG96cmgTn2qSzjwr2qvfNEuhunv6FNeMFGa9bx6mQ", "attributes": [ { "trait_type": "Background", "value": "Orange" }, { "trait_type": "Eyes", "value": "Bored" } ] } ``` **Result:** Complete NFT metadata without manual enrichment. *** ## Unified backup If your primary provider experiences an outage, Uniblock seamlessly switches to backup providers without returning errors to your application. **Failover chain example:** 1. Primary: Alchemy (fastest, most reliable) 2. Backup 1: QuickNode (high reliability) 3. Backup 2: Ankr (stable fallback) **Typical failover time:** \< 500ms *** ## Common polyfill scenarios ### Multi-chain applications **Challenge:** Building a portfolio tracker that supports 20+ chains, but no single provider covers all chains. **Solution:** Uniblock automatically routes each chain to the provider with best coverage: * Ethereum → Alchemy * Polygon → Covalent * Arbitrum → QuickNode * Base → Moralis **Your code:** ```bash Single request, multiple providers behind the scenes theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/portfolio?address=0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb&chainIds=1,137,42161,8453' \ --header 'x-api-key: YOUR_API_KEY' ``` **Result:** Complete portfolio data across all chains from a single API call. ### Historical analytics **Challenge:** Analyzing token transfers over 3 years, but provider only has 1 year of history. **Solution:** Uniblock automatically: 1. Fetches recent data (last year) from primary provider 2. Backfills older data (2+ years ago) from archival provider 3. Merges datasets into single response **Result:** Complete historical dataset without manual data stitching. ### NFT marketplaces **Challenge:** Displaying NFT collections with complete metadata, but providers have inconsistent metadata quality. **Solution:** Uniblock automatically: 1. Fetches basic NFT data from primary provider 2. Enriches with high-quality metadata from specialized NFT providers 3. Returns complete NFT details with images, attributes, and rarity **Result:** Rich NFT displays without multiple API calls or manual enrichment. *** ## Key benefits Access all chains and historical periods without provider limitations. Missing data automatically retrieved from alternative providers. Works automatically - no setup or manual provider management. Always receive complete datasets regardless of provider gaps. *** ## Monitoring polyfill activity Track polyfill events in the Uniblock dashboard: * **Polyfill count** - How many times data was filled from backup providers * **Gap types** - Chain coverage, historical data, or metadata gaps * **Provider usage** - Which providers are filling which gaps * **Data completeness** - Percentage of requests requiring polyfill **Insights available:** * Identify which chains require most polyfilling * Understand historical data coverage across providers * Optimize provider selection based on your data needs *** ## Best practices **Request all needed data in single calls** - Uniblock handles multi-provider routing automatically. Don't split requests unnecessarily. **Use date ranges for historical queries** - Specify exact date ranges to help Uniblock optimize provider selection for historical data. **Monitor polyfill patterns** - Review dashboard to understand which data types require most polyfilling. This helps optimize your data strategy. **Trust the automation** - Don't manually switch providers or implement fallback logic. Uniblock handles this more efficiently. *** ## Next steps Learn how backup providers ensure high availability. Understand automatic retry logic for failed requests. Optimize provider selection for cost and performance. Monitor polyfill activity and data completeness. *** ## Common pitfalls **Don't assume single-provider responses** - Polyfilled responses may combine data from multiple providers. This is expected and ensures completeness. **Data format consistency** - While Uniblock normalizes responses, minor differences may exist between providers. Test thoroughly with your data models. **Historical data limits** - Some chains have limited historical data across all providers. Uniblock polyfills where possible but can't create data that doesn't exist. **Metadata quality variance** - NFT metadata quality varies by provider. Uniblock selects best available sources but metadata completeness depends on original sources. *** Create your free account and start building with unified blockchain infrastructure across 300+ chains.

Waterfall routing is the execution model Uniblock uses to reduce failover latency during provider selection. Instead of waiting for one provider to fully fail before the next provider is allowed to start, Uniblock can overlap provider attempts in a controlled sequence. The current backend implementation uses waterfall execution as the default backup strategy for routed requests. Providers are still tried in priority order, but the system can begin the next provider before the previous one fully finishes when a timeout window is reached. **Use waterfall routing when you need:** * Faster recovery from slow or hanging upstream providers * Lower tail latency during failover * Priority-ordered backup behavior without strictly serial waiting * Better resilience when some providers are degraded but not fully down Waterfall routing works behind the same routed request flow you already use with Uniblock. You do not need a separate API integration to benefit from it. *** ## How it works At a high level, Uniblock still builds a normal provider priority list first. Waterfall routing changes how that list is executed: 1. **Build execution plan** - Uniblock generates the provider list for the request, applies provider filters, removes disabled or rate-limited options, and preserves the final routing order 2. **Start provider 1** - The top provider begins processing 3. **Wait briefly for a result** - If the provider fulfills the request quickly, execution stops and the response is returned 4. **Open the next step in the waterfall** - If the provider is still pending after the waterfall timeout, Uniblock starts the next provider in the priority list 5. **Return the first fulfilled result** - As soon as one provider fulfills the request, that response wins 6. **Drain remaining work** - Any in-flight handlers are allowed to finish in the background so request history is complete In the current implementation, the waterfall executor uses: * A **3 second waterfall timeout** * Up to **3 concurrent active provider handlers** * A **first fulfilled result wins** completion rule *** ## What changes compared to standard backup failover? Traditional backup failover is fully sequential: 1. Try provider A 2. Wait for provider A to succeed or fail 3. Then try provider B 4. Then try provider C Waterfall routing is still ordered, but it does not force the system to wait for every slow provider to finish before moving on. ### Example timeline Assume your routed priority list is: 1. Alchemy 2. QuickNode 3. Ankr With waterfall routing: 1. **0s** - Alchemy starts 2. **3s** - If Alchemy is still hanging, QuickNode starts 3. **6s** - If neither has fulfilled the request, Ankr starts 4. **6.2s** - If QuickNode fulfills successfully, Uniblock returns QuickNode's response immediately This means a slow provider can still win if it finishes first, but it no longer blocks the rest of the backup chain from starting. *** ## When Uniblock skips a provider before the waterfall Not every provider in the priority list results in an outbound request. Before a handler is started, Uniblock checks: * Whether the provider has a handler for that endpoint * Whether request constraints pass * Whether the chain is supported * Whether the provider is allowed by `supportedProviders` * Whether the provider was filtered out by rate-limit state * Whether the provider key can be loaded If any of those checks fail, the provider is skipped and the waterfall advances to the next eligible option without waiting. *** ## Fulfilled vs unfulfilled Waterfall execution stops only when a provider **fulfills** the request. Requests are treated as **unfulfilled** when a provider: * Throws an unhandled handler error * Returns a provider error * Times out from the request's point of view * Fails validation or transform logic * Cannot satisfy the endpoint constraints If no provider fulfills the request, Uniblock waits for any remaining in-flight handlers to finish and then returns the normal routed error response. *** ## Relationship to auto-routing and backup providers Waterfall routing does not replace auto-routing or backup providers. It sits inside that system: * **Auto-routing** decides the provider priority order * **Backup providers** define what the next eligible options are * **Waterfall routing** controls how quickly Uniblock advances through that ordered list That means waterfall routing improves failover latency without changing the fact that provider order still matters. If a request is forced to a specific provider, or filtered to a single provider through request options, the waterfall has fewer or no alternate providers to open. *** ## Rate limits and waterfall routing Waterfall routing helps with **provider-level** failures and slowdowns, but it does not bypass Uniblock plan limits. * If an upstream provider is unavailable or rate-limited, the waterfall can move to the next eligible provider * If Uniblock itself returns a `429` because your project hit its plan-level limit, the waterfall does not override that limit This is the same distinction described in the backup provider flow. *** ## Observability notes Waterfall execution affects how provider attempts appear in analytics and logs: * The first provider in the priority list is still the first provider started * Later providers may begin before earlier providers have fully completed * History entries can be recorded in **resolution order**, not strict initiation order That means waterfall attempts may look slightly different from a purely sequential fallback chain when you inspect request history. *** ## Why this design is useful Waterfall routing is a practical middle ground between two extremes: * **Strict serial failover** is simple but slow when providers hang * **Fan-out to every provider at once** is fast but expensive and wasteful Waterfall routing keeps the cost and control benefits of an ordered backup list while reducing the latency penalty of waiting on degraded providers. *** ## Related guides See how Uniblock chooses provider order before waterfall execution begins.

This page documents the Uniblock error codes currently defined in the validation catalog. These codes cover: * Request validation failures * JSON-RPC request format errors * Response processing failures * Success and fallback classification codes Uniblock `429` responses are plan-based rate limits, not generic validation errors. See [Rate limits](#rate-limits) below for how to handle them. ## Format Uniblock error codes follow this pattern: ```text theme={null} UR-- ``` Examples: * `UR-400-02` for an invalid parameter * `UR-422-01` for an unprocessable provider response * `UR-200-00` for a successful request classification ## Important behavior for JSON-RPC Some JSON-RPC validation errors return HTTP `200` with a JSON-RPC error payload instead of an HTTP `4xx` status. In those cases, the Uniblock error code still tells you what went wrong. This applies to: * `UR-400-03` Parse Error * `UR-400-04` Invalid Request * `UR-400-08` Unsupported Method * `UR-400-10` JSON-RPC Batch Size Exceeded ## Success and fallback codes | Code | Title | HTTP Status | Retryable | Meaning | | ----------- | ------------------ | ----------- | --------- | ------------------------------- | | `UR-200-00` | Request Successful | `200` | No | Request completed successfully. | ## Request validation codes | Code | Title | HTTP Status | Retryable | Meaning | Suggested action | | ----------- | ---------------------------- | ----------- | --------- | --------------------------------------------------------------------- | ----------------------------------------------------------------------------------- | | `UR-400-02` | Invalid Parameter | `400` | No | A query or body parameter is invalid. | Review your request parameters against the endpoint spec. | | `UR-400-03` | Parse Error | `200` | No | The JSON-RPC request body is not valid JSON. | Fix JSON syntax issues such as malformed objects, trailing commas, or bad escaping. | | `UR-400-04` | Invalid Request | `200` | No | The JSON-RPC request shape or parameters are invalid. | Ensure the request follows the JSON-RPC 2.0 format and uses valid params. | | `UR-400-05` | Invalid Pagination | `400` | No | REST pagination exceeded the maximum limit or used an invalid cursor. | Keep page size at `1000` or below and verify the cursor is valid. | | `UR-400-06` | Invalid Address Format | `400` | No | The blockchain address format is invalid. | Validate the address format for the target chain before sending the request. | | `UR-400-07` | Invalid Transaction Hash | `400` | No | The transaction hash format is invalid. | Send a valid transaction hash for the target chain. | | `UR-400-08` | Unsupported Method | `400` | No | The requested JSON-RPC method is not supported or not whitelisted. | Use a supported method for the selected network. | | `UR-400-10` | JSON-RPC Batch Size Exceeded | `200` | No | The batch contains more than `1000` JSON-RPC calls. | Split large batches into smaller requests. | ## Response processing codes These codes mean the provider responded successfully at the HTTP layer, but Uniblock could not safely process the response. | Code | Title | HTTP Status | Retryable | Meaning | Suggested action | | ----------- | ------------------------------ | ----------- | --------- | ------------------------------------------------------------------------------------ | ------------------------------------------------------ | | `UR-422-01` | Unprocessable Response | `422` | No | The provider returned a successful response, but the content could not be processed. | Retry later or switch providers if the issue persists. | | `UR-422-02` | Response Parsing Failed | `422` | No | The provider returned content that could not be parsed as valid JSON. | Retry after a short delay. | | `UR-422-03` | Response Transformation Failed | `422` | No | The provider response could not be transformed into Uniblock's expected format. | Retry or contact support if it continues. | | `UR-422-04` | Response Validation Failed | `422` | No | The provider response did not match the expected schema or contained invalid data. | Retry or use another provider if available. | ## Common examples ### Invalid REST parameter If you send an invalid query or body parameter, Uniblock may return: ```json theme={null} { "error": { "code": "UR-400-02", "title": "Invalid Parameter" } } ``` ### Invalid JSON-RPC body If your JSON-RPC body is malformed, Uniblock may return HTTP `200` with a JSON-RPC error and the matching Uniblock code: ```json theme={null} { "jsonrpc": "2.0", "id": 1, "error": { "code": -32700, "message": "Parse error", "uniblockCode": "UR-400-03" } } ``` ### Provider response could not be normalized If an upstream provider responds in an unexpected format, Uniblock may return: ```json theme={null} { "error": { "code": "UR-422-03", "title": "Response Transformation Failed" } } ``` ## How to troubleshoot 1. Identify the Uniblock code returned in the response. 2. Check whether the issue is a request validation problem, a rate limit, or a provider response problem. 3. Fix request formatting issues locally before retrying. 4. If the code is in the `UR-422-*` family and persists, retry later or contact support with the request ID. ## Rate limits If you receive a `429` error, your project has reached the request limit included with your current Uniblock plan. A `429` does **not** mean Uniblock is down. It means your traffic exceeded your current plan window. ### Rate-limit quick reference | Question | Short answer | | -------------------------- | ------------------------------------------------ | | What triggers `429`? | Request rate above your plan limit | | Is this provider-specific? | No, this is Uniblock plan-level | | Should I retry? | Yes, with delay/backoff | | Do backups bypass `429`? | No, backup routing does not override plan limits | | Long-term fix? | Reduce traffic, optimize usage, or upgrade plan | ### What should I do if I hit a rate limit? Add exponential backoff and jitter before retrying `429` responses. Lower polling frequency, cache stable data, and batch requests where possible. Verify whether release changes, cron jobs, or retries increased request volume. If sustained demand exceeds your current allowance, upgrade to a plan with more throughput. ### Retry pattern (recommended) ```javascript theme={null} // Exponential backoff with jitter for 429 responses. async function requestWithBackoff(fn, maxRetries = 5) { for (let attempt = 0; attempt <= maxRetries; attempt++) { const res = await fn(); if (res.status !== 429) return res; if (attempt === maxRetries) return res; const base = 250 * Math.pow(2, attempt); const jitter = Math.floor(Math.random() * 200); await new Promise((r) => setTimeout(r, base + jitter)); } } ``` ### Rate limit FAQ #### Are rate limits based on my Uniblock plan? Yes. Rate limits are based on the limits included with your Uniblock plan. #### Does a 429 mean the API is down? No. A `429` means your project has exceeded its allowed request rate. It does not mean the platform is unavailable. #### Will requests start working again? Yes. Once traffic falls back within your allowed limit window, requests will succeed again. #### Can I increase my rate limits? Yes. If you need more throughput, please upgrade your plan or contact us to discuss a plan that matches your usage. #### Should I retry 429 responses? Yes, but retries should include a short delay or exponential backoff to avoid sending another burst immediately. #### Do backup providers avoid 429 errors? No. Backup providers help with upstream provider failures, but they do not bypass your Uniblock plan limits. ### Example 429 response ```json theme={null} { "error": { "code": 429, "message": "Too Many Requests" } } ``` ## Related guides * [Authentication](/guides/uniblock/authentication) * [Analytics & Logs](/guides/uniblock/uniblock-analytics) # Uniblock FAQ: API keys, routing, errors, and rate limits Source: https://docs.uniblock.dev/guides/uniblock/faq Answers to common Uniblock questions on API keys, auto-routing, backup providers, rate limits, errors, plan pricing, and debugging in production.

Uniblock is a blockchain infrastructure layer that gives you one unified API across many chains and providers. Instead of integrating directly with providers like Alchemy, QuickNode, Infura, Moralis, or Covalent one by one, you send requests through Uniblock and get: * One API key * Auto-routing across providers * Backup failover when providers have issues * Normalized response formats * Access to many supported chains through the same interface If you are just getting started, use the [Unified API Quickstart](/guides/uniblock/unified-api-quickstart). ## Why use Uniblock instead of integrating with a single provider directly? Use Uniblock when you want to reduce provider management overhead and improve reliability. A direct provider integration can be simpler if you only need one chain and one provider, but Uniblock is usually more valuable when you need: * Multi-chain coverage * Automatic failover * Consistent schemas across providers * Centralized analytics and logs * One integration instead of managing multiple provider APIs and keys ## How do I make my first API call? 1. Create a project in the dashboard. 2. Copy your Uniblock API key. 3. Send the key in the request header. 4. Call a Unified API endpoint. Example: ```bash theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/token/balances?chainId=1&address=0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb' \ --header 'x-api-key: YOUR_API_KEY' ``` For a step-by-step walkthrough, see [Unified API Quickstart](/guides/uniblock/unified-api-quickstart). ## How do I authenticate requests? Include your Uniblock API key in the request header as `x-api-key`. Every request to the Unified API should include a valid project key. If you need more detail, see [Authentication](/guides/uniblock/authentication). ## Is auto-routing enabled by default? Yes. Auto-routing is enabled by default for all Uniblock API keys. You do not need to manually choose a provider for standard usage. Uniblock evaluates providers for reliability, latency, and cost, routes to the best available option, retries failures, and fails over to backups when needed. See [Auto-routing](/guides/uniblock/autorouting/uniblock-auto-routing) for the full flow. ## Do backup providers prevent all failures? No. Backup providers help when an upstream provider is unavailable, returns errors, or hits its own provider-specific limit. They do not override Uniblock plan-level limits. If Uniblock returns a `429`, that means your project has reached the request limit included with your current plan. That is different from a provider-specific failure inside the routing layer. See: * [Backup Providers](/guides/uniblock/autorouting/uniblock-backup) * [Error Codes & Rate Limits](/guides/uniblock/error-codes#rate-limits) ## What does a 429 mean? A `429` means your project has reached the request limit available under your current Uniblock plan. It does not mean: * The API is down * A provider outage occurred * Backup routing failed In most cases, you should reduce request frequency, retry with backoff, or move to a plan with more throughput. ## Does Uniblock normalize provider responses? Yes. Uniblock transforms provider-specific responses into a unified format so your application does not need provider-specific parsing logic for common Unified API endpoints. This is one of the main reasons to use Uniblock for multi-provider and multi-chain applications. ## Can I bring my own provider keys? Yes. Uniblock supports custom fallback lists with external provider keys, which lets you consume your own provider credits first and keep Uniblock auto-routing as a final fallback. This is useful if you already have relationships or spend commitments with specific providers. See [Backup Providers](/guides/uniblock/autorouting/uniblock-backup). ## What is data consensus, and when should I use it? Data consensus queries multiple providers and compares results to improve confidence in the returned data. It is most useful for critical reads where correctness matters more than the extra latency and cost. Use it selectively for things like: * Critical balance checks * Pricing-sensitive workflows * Auditing or verification flows ## Why did I get a 403? Common reasons include: * Your API key or project credentials are missing or invalid * The API key has been disabled * Your project does not have permission for the requested endpoint * Your project does not have access to the requested blockchain network If the response includes a Uniblock error code, check [Error Codes & Rate Limits](/guides/uniblock/error-codes) first and then verify your project configuration in the dashboard. Fast triage for `403`: verify API key validity, endpoint access, and chain permissions in the dashboard before retrying. ## Why did I get a 400? A `400` usually means the request itself is invalid. Common examples include: * Invalid query or body parameters * Invalid blockchain address format * Invalid transaction hash format * Unsupported JSON-RPC method * Pagination or cursor errors These are usually not retryable until you fix the request. ## Why did I get a 422? A `422` means the upstream provider returned a successful HTTP response, but Uniblock could not safely parse, transform, or validate the content. This usually points to a provider response problem rather than a malformed request from your application. If it persists: 1. Retry after a short delay. 2. Check API logs and request details. 3. Contact support with the request ID if the issue continues. Persistent `UR-422-*` errors usually indicate an upstream response issue. Include request ID and endpoint when contacting support. ## Why do I see "gas required exceeds" on `eth_call` or `eth_estimateGas`? Public JSON-RPC providers apply a gas cap to `eth_call` and `eth_estimateGas` to protect shared infrastructure. The most common cap is `16777216` (2^24, roughly 16.7 million), which produces errors like: ```text theme={null} gas required exceeds allowance (16777216) ``` This cap is enforced by the upstream provider that Uniblock routed the request to, not by Uniblock itself. It applies to simulation and gas-estimation calls, and to large contract deployments that would exceed the cap during estimation. To work around it: 1. **Bring your own provider key.** Add an API key from a provider whose plan allows a higher gas cap and route through it via [Add Your Own API Key](/guides/uniblock/autorouting/add-your-own-api-key). Requests then consume your provider's quota with its configured limits. 2. **Use a direct provider integration.** For provider-specific behavior that the shared RPC does not expose, use a [Direct Provider](/reference/direct/direct-providers/overview) endpoint tied to a provider account you control. 3. **Set an explicit `gas` value.** If your client is calling `eth_estimateGas` before a transaction, pass a known-good `gas` value in the transaction to skip estimation. 4. **Contact support.** If none of the above work for a deployment or simulation you need to run, reach out with the request ID and target chain so the team can advise on the right routing. ## Why do some JSON-RPC errors return HTTP 200? JSON-RPC errors can be returned inside a valid JSON-RPC response body while the HTTP layer still returns `200`. In those cases, the transport succeeded, but the JSON-RPC request itself failed. That is why you may see things like: * Parse error * Invalid request * Batch size exceeded with an HTTP `200` plus a JSON-RPC error payload. ## How do I debug failed requests? Start with these steps: 1. Check the HTTP status code. 2. Check the Uniblock error code if present. 3. Review the request parameters and headers. 4. Inspect API logs in the dashboard. 5. Look at provider attempts and failures if failover occurred. The most useful docs are: * [Analytics & Logs](/guides/uniblock/uniblock-analytics) * [Error Codes & Rate Limits](/guides/uniblock/error-codes) ## Debug checklist Determine whether the failure is auth/permissions (`403`), request-shape (`400`), rate-limit (`429`), or response-processing (`422`). Confirm headers, params, chain ID, and endpoint path. Keep the request ID for escalation. Use dashboard API logs to inspect latency, provider attempts, and failover paths. Share request ID, endpoint, time window, and sample payload with support. ## Where can I see which provider handled my request? Use the API logs in the dashboard. Logs help you inspect request status, endpoint, response time, and provider activity, including failover attempts where applicable. ## Which APIs does Uniblock support? Uniblock provides unified access across multiple API categories, including: * Token APIs * NFT APIs * Transaction APIs * Market data APIs * Scans APIs * JSON-RPC The exact endpoint list is available in the API reference and explorer. ## Which chains and providers are supported? Uniblock supports many blockchains and integrates with many blockchain data providers. The docs describe support for 300+ blockchains and 55+ providers. For chain-by-chain details, check the supported chains and API reference sections in the docs. ## Does Uniblock support MCP? Yes. Uniblock provides an MCP server that can be connected to compatible AI clients. This exposes Uniblock tools and Unified API endpoints through MCP. See [MCP Setup](/reference/unified-api/uniblock-mcp-setup). ## What are Uniblock's official domains? Uniblock operates across multiple domains for marketing and outreach.

Explore all available endpoints and interactive playgrounds # Uniblock overview: unified APIs and auto-routing Source: https://docs.uniblock.dev/guides/uniblock/overview-uniblock How Uniblock simplifies multi-chain development with a unified API, auto-routing across 55+ providers, and normalized data across 300+ blockchains. ## What Uniblock does Uniblock is a blockchain infrastructure layer that abstracts away the complexity of working with multiple data providers and chains. Instead of managing dozens of API keys, handling provider outages, and normalizing inconsistent data formats, you get one unified interface that works everywhere. **Core value proposition:** * **One API key** replaces 55+ provider integrations * **Auto-routing** ensures requests always succeed via intelligent failover * **Normalized data** provides consistent formats across all providers * **Multi-chain support** for 300+ blockchains with identical API patterns New to Uniblock? Start with the [Quickstart Guide](/guides/getting-started/uniblock-quickstart-guide) to make your first API call in 5 minutes. *** ## How it works When you make a request to Uniblock: 1. **Request received** - Your API call hits Uniblock's routing layer 2. **Provider selection** - Auto-routing picks the optimal provider based on reliability, latency, and cost 3. **Data retrieval** - Request is sent to the selected provider (e.g., Alchemy, QuickNode, Covalent) 4. **Normalization** - Response is transformed into Uniblock's unified format 5. **Validation** - Data is verified for completeness and accuracy 6. **Failover** - If the provider fails, request automatically retries with backup providers 7. **Response** - You receive consistent, reliable data ```bash Example: Token balance request theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/token/balances?chainId=1&address=0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb' \ --header 'x-api-key: YOUR_API_KEY' ``` ```json Response: Normalized across all providers theme={null} { "data": [ { "tokenAddress": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", "symbol": "USDC", "balance": "1000000000", "decimals": 6, "balanceFormatted": "1000.00", "valueUsd": "1000.00" } ] } ``` *** ## Key features ### Auto-routing Uniblock automatically routes requests to the best available provider based on real-time performance metrics. If a provider is down or slow, requests instantly failover to backup providers. **Benefits:** * **99.9% uptime** - No single point of failure * **Optimized latency** - Routes to fastest provider for your region * **Cost efficiency** - Balances requests across providers to minimize costs * **Zero configuration** - Works automatically, no manual setup required **How it works:** * Monitors provider health in real-time * Tracks latency, error rates, and success rates * Maintains fallback chains for every endpoint * Retries failed requests automatically [Learn more about auto-routing →](/guides/uniblock/autorouting/uniblock-auto-routing) ### Data normalization Different providers return data in different formats. Uniblock normalizes all responses into a consistent schema, so you never have to write provider-specific parsing logic. **Example: Token balance formats** | Provider | Balance format | Decimals | | -------- | ----------------------- | -------------- | | Alchemy | `"1000000000"` (string) | Separate field | | Moralis | `1000000000` (number) | Separate field | | Covalent | `"1000.00"` (formatted) | Included | **Uniblock normalized:** ```json theme={null} { "balance": "1000000000", "decimals": 6, "balanceFormatted": "1000.00" } ``` All three formats are unified, so your code works regardless of which provider is used. [Learn more about data normalization →](/guides/uniblock/autorouting/uniblock-data-normalization) ### Data consensus For critical queries, Uniblock can query multiple providers simultaneously and return consensus data. This ensures accuracy and catches provider-specific bugs or stale data. **When to use:** * High-value transactions requiring verification * Auditing and compliance scenarios * Critical balance checks before transfers **How it works:** * Queries 2-3 providers in parallel * Compares responses for consistency * Returns data only if providers agree * Flags discrepancies for investigation Data consensus increases latency and costs. Use it selectively for critical operations. ### Polyfilled data Some providers have incomplete data for certain chains or time periods. Uniblock automatically detects gaps and fills them using alternative providers. **Example scenarios:** * Provider A has Ethereum data but missing Polygon data → Uniblock uses Provider B for Polygon * Provider C has recent transactions but missing historical data → Uniblock backfills from Provider D * Provider E returns incomplete NFT metadata → Uniblock enriches from Provider F **Result:** You always get complete data without manual provider switching. [Learn more about data polyfill →](/guides/uniblock/autorouting/uniblock-polyfill) ### Unified backup If your primary provider experiences an outage, Uniblock seamlessly switches to backup providers without returning errors to your application. **Failover chain example:** 1. Primary: Alchemy (fastest, most reliable) 2. Backup 1: QuickNode (high reliability) 3. Backup 2: Ankr (stable fallback) **Typical failover time:** \< 500ms *** ## Supported APIs Uniblock provides unified access to multiple API categories: Balances, transfers, prices, allowances, and token metadata across all chains. Collections, metadata, floor prices, ownership, and transfer history. Transaction history, receipts, gas estimation, and status tracking. Real-time prices, historical charts, volume, and trending tokens. Block explorer data, contract verification, and source code access. Direct node access with auto-routing for all supported chains. [View all API endpoints →](/reference/unified-api-reference-overview) *** ## Supported providers Uniblock integrates with 55+ blockchain data providers to ensure comprehensive coverage and reliability, including: Alchemy, QuickNode, Infura, Ankr, Covalent, Moralis, Blockdaemon, Chainstack, TonAPI, Helius, and more. *** ## When to use Uniblock ### Use Uniblock when you need: * **Multi-chain support** - Building apps that work across multiple blockchains * **High reliability** - Production apps that can't tolerate provider outages * **Consistent data** - Normalized formats across all providers and chains * **Fast integration** - One API key instead of managing multiple providers * **Cost optimization** - Automatic routing to most cost-effective providers ### Consider alternatives when: * **Single provider is sufficient** - If you only need one chain and one provider, direct integration may be simpler * **Extreme latency requirements** - Direct provider connections may be 50-100ms faster (though less reliable) *** ## Common use cases ### Wallet applications Display token balances, NFTs, and transaction history across multiple chains with a single integration.

Use [Direct API](/reference/direct/direct-providers/overview) for provider-specific functionality. **Rate limits** - Rate limits apply per API key, not per provider. Monitor your usage in the [dashboard](https://dashboard.uniblock.dev) to avoid throttling. **Chain ID consistency** - Always use numeric chain IDs (e.g., `1` for Ethereum) or official string identifiers (e.g., `solana`). Inconsistent chain IDs cause routing errors. *** ## Need help? * **Documentation** - Search these docs for detailed guides and API references * **Support** - Contact us at [uniblock.dev/support](https://uniblock.dev/support) * **Dashboard** - Monitor usage and manage projects at [dashboard.uniblock.dev](https://dashboard.uniblock.dev) *** Create your free account and start building with unified blockchain infrastructure across 300+ chains.

It shows response times, request volume, endpoint trends, and detailed logs for every call. ## Project statistics Uniblock Analytics provides the following data for your project: * **Average latency**: average API response time; lower is better for user experience * **Successful requests**: count of completed requests * **Failed requests**: count of requests that returned an error or did not complete * **Total requests**: cumulative request count for activity and usage patterns * **Endpoint calls over time**: chart of successful, failed, and total requests over time ## API key analytics In addition to project-wide analytics, Uniblock provides the same metrics broken down per API key: average response time, failed requests, total requests, and total usage. Use this to spot anomalies tied to a specific key or environment (for example, a staging key spiking in errors while production stays clean). ## API logs Scroll to **See Detailed Logs** at the bottom of the Analytics tab for a per-request table showing: method, endpoint, status code, provider used, response time, and timestamp. ### Why logs matter API logs show how your application behaves in production. Use them to: * Identify and diagnose issues as they happen * Monitor API health and response-time trends * Track request patterns across endpoints * Detect unexpected or suspicious activity ### Reading the logs table Each row in the logs table summarizes one outbound call, including any provider fallback attempts that occurred: * **Method**: HTTP method (`GET` or `POST`) * **Endpoint**: API endpoint accessed (e.g. `/v1/token/metadata`) * **Status**: success or error status code * **Provider**: provider that returned the final response * **Response**: provider response(s) attempted for the call (multiple when fallback routing fired) * **Response time**: end-to-end latency for the request * **Date**: exact timestamp when the request was made ### Detailed request logs Click any log row to expand the full request detail, which includes every fallback attempt across providers: * **HTTP method**: e.g. `GET` * **Endpoint name**: e.g. `TokenMetadata` * **Endpoint path**: e.g. `/v1/token/metadata` * **Timestamp**: exact request time * **Response time**: server processing duration * **Headers**: request metadata (`Host`, `User-Agent`, `Accept`, and others) * **Query parameters**: additional request context * **Request body**: payload for `POST` or `PUT` requests * **Response headers & body**: provider response data (multiple entries appear when fallback routing was used) ### Filtering and searching Use the filter controls at the top of the logs table to narrow by provider, status code, endpoint, or time range. The search bar matches keywords or error messages across all log fields. *** Create your free account and start building with unified blockchain infrastructure across 300+ chains.

Estimated time: under 2 minutes. This guide assumes you already have an Uniblock project. If not, follow the [Uniblock Quickstart Guide](/guides/getting-started/uniblock-quickstart-guide) first. Open your [Uniblock dashboard](https://dashboard.uniblock.dev) and navigate to your project. Your API key is displayed on the **Overview** page; click the copy icon next to it. In the left sidebar of your project, go to **Endpoints → API Tester**. This opens the Uniblock Explorer in a new tab. On the Explorer page, click the **Authorize** button at the top. Paste your Uniblock API key into the `X-API-Key` field and click **Authorize**, then **Close**. All subsequent requests in this session will use your key. Find and expand the `/token/metadata` endpoint. Click **Try it out** to enable the input fields. Example values are pre-filled in the required fields. You can use them as-is or enter your own `chainId` and token address. Click **Execute** to send the request. The response body appears below the Execute button with a `200` status code and the token metadata JSON. That's it: you've made your first authenticated Unified API call. *** Continue on to the other guides in the Unified API section for more detail on authentication, analytics, and auto-routing features. *** Create your free account and start building with unified blockchain infrastructure across 300+ chains. Explore all available endpoints and interactive playgrounds # Airdrops and Growth Campaigns Source: https://docs.uniblock.dev/guides/use-cases/airdrops-and-growth-campaigns Use Uniblock to monitor airdrop eligibility, distribution activity, NFT campaigns, holder wallets, and on-chain growth events across chains. Uniblock does not replace your claim contract or distribution logic, but it can cover a large part of the surrounding campaign data layer: holder checks, transfer tracking, event monitoring, NFT ownership checks, and post-launch reporting. ## Best-fit workflows * Monitor token or NFT distribution progress * Verify recipient activity and holdings * Trigger internal workflows from transfer or contract events * Build campaign dashboards for launch teams and community ops *** ## Recommended APIs * `GET /token/transfers` * `GET /token/activity` * `GET /token/balance` * `GET /nft/is-airdrop` * `GET /nft/is-nft-holder` * `GET /nft/transfers` * [Webhook quickstart](/reference/webhook/webhook-quickstart) *** ## Suggested implementation flow ### 1. Define the eligibility read path Depending on the campaign, eligibility can come from: * token balances * NFT ownership * historical wallet activity * contract interactions Use the unified read layer to centralize those checks before users ever reach the claim flow. ### 2. Monitor campaign movement Once distribution begins, use token, NFT, and transaction endpoints to track: * how many wallets received assets * which wallets moved or sold immediately * whether claim activity is still active ### 3. Add webhook-driven operations Webhooks are useful for: * internal notifications when claims happen * syncing campaign databases * triggering CRM or growth workflows * detecting large movement from campaign wallets ### 4. Close the loop with analytics and logs After launch, use: * [Analytics & Logs](/guides/uniblock/uniblock-analytics) to understand request usage during campaign spikes and debug malformed requests *** ## Common pitfalls Eligibility logic is application-specific. Keep your business rules in your own backend even if Uniblock powers the underlying reads. Campaign traffic is bursty. Load-test your own systems and watch Uniblock rate limits before a public launch. *** ## Related docs * [NFT API overview](/reference/unified-api/api-overview-nft) * [Token API overview](/reference/unified-api/api-overview-token) * [Rate limits](/guides/uniblock/error-codes#rate-limits) # DAO Dashboards and Governance Source: https://docs.uniblock.dev/guides/use-cases/dao-dashboards-and-governance Build DAO dashboards on Uniblock with treasury visibility, governance-token monitoring, proposal activity, and event-driven contract tracking. DAO tooling usually needs visibility into treasury wallets, governance-token movement, and contract events rather than a single endpoint category. Uniblock works well as a read and monitoring layer across those requirements. ## Best-fit workflows * Treasury dashboards * Governance token monitoring * Contract-event monitoring for voting or execution contracts * Contributor and wallet activity tracking *** ## Recommended APIs * [Token API overview](/reference/unified-api/api-overview-token) * [Transaction API overview](/reference/unified-api/api-overview-transaction) * [Webhooks overview](/reference/webhook/webhooks-overview) * [JSON-RPC overview](/reference/unified-api/overview-jsonrpc) Useful starting points: * `GET /token/balance` * `GET /token/activity` * `GET /token/allowances` * `GET /transactions` * contract-event webhooks *** ## Suggested implementation flow ### 1. Build treasury visibility Start by indexing known treasury and operational wallets. Use token balances and transactions to create: * treasury composition views * outflow and inflow reports * multisig activity summaries ### 2. Track governance token movement Use token activity and transfer data to monitor: * whale movement * delegate or contributor wallet changes * unusual governance-token concentration shifts ### 3. Monitor governance contracts Use contract-event webhooks for: * proposal creation * execution events * protocol-specific governance actions This is especially useful when the DAO runs custom contracts and you want event-driven automation around them. ### 4. Use JSON-RPC where contract-level detail matters If the governance flow depends on contract state reads that are not modeled in the Unified API, use JSON-RPC for contract calls while keeping Uniblock as the shared routing layer. *** ## Common pitfalls Governance data is often split between token movement and contract state. Do not assume one source alone is enough for a full DAO dashboard. Allowance data can be important for operational wallets. If your DAO uses treasury automation, include approvals and permissions in reviews. *** ## Related docs * [Contract event webhook type](/reference/webhook/webhook-types/event-trigger-contract-event) * [Token API overview](/reference/unified-api/api-overview-token) * [Authentication guide](/guides/uniblock/authentication) # DeFi Dashboards and Analytics Source: https://docs.uniblock.dev/guides/use-cases/defi-dashboards-and-analytics Use Uniblock to build DeFi dashboards and analytics with token price, transaction history, liquidity, and market activity data across chains.

Uniblock helps by combining normalized token and transaction data with market-data endpoints and optional provider-specific access through Direct API. ## Best-fit use cases * Token watchlists and market overview pages * Treasury dashboards for protocol-owned assets * Yield, LP, or vault monitoring tools * Internal analytics for on-chain protocol activity *** ## Recommended APIs * [Market Data API overview](/reference/unified-api/api-overview-market-data) * [Token API overview](/reference/unified-api/api-overview-token) * [Transaction API overview](/reference/unified-api/api-overview-transaction) * [Direct API overview](/reference/direct/direct-providers/overview) Key endpoints to start with: * `GET /market-data/price` * `GET /market-data/history` * `GET /market-data/chart-range` * `GET /market-data/trending` * `GET /token/balance` * `GET /token/transfers` * `GET /transactions` *** ## Suggested implementation flow ### 1. Build the market layer Use market-data endpoints to power: * spot prices * 24 hour volume * historical charts * trending or top-moving token lists ```bash theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/market-data/price?chainId=1&tokenAddress=0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48' \ --header 'x-api-key: YOUR_API_KEY' ``` ### 2. Add protocol and treasury positions Use token balance and transaction endpoints to monitor wallets tied to: * protocol treasuries * reward distribution wallets * multisigs * liquidity management accounts ### 3. Add event-driven workflows If a dashboard needs to react quickly to transfers or contract activity, add: * [Address activity webhooks](/reference/webhook/webhook-types/event-trigger-address-activity) * [Contract event webhooks](/reference/webhook/webhook-types/event-trigger-contract-event) These are useful for vault deposits, treasury movements, and settlement events. ### 4. Use Direct API when you need provider-specific depth Some DeFi products eventually need provider-native features or niche datasets. That is where [Direct API](/reference/direct/direct-providers/overview) is the right extension point. Start with Unified API for portability. Move into Direct API only when the unified schema does not expose the specific provider feature you need. *** ## Where JSON-RPC fits Use [JSON-RPC](/reference/unified-api/overview-jsonrpc) for: * contract reads with `eth_call` * pending state inspection * gas estimation * raw transaction submission from backend services This is useful when your DeFi backend must interact with contracts directly rather than just read indexed data. *** ## Common pitfalls DeFi apps often mix indexed data and node data. Be explicit about which layer is used for pricing, balances, and execution-critical reads. If a view is latency-sensitive, avoid over-fetching multiple chart and balance endpoints in the same render path. Split summary views from detailed panels. *** ## Related docs * [Market Data API overview](/reference/unified-api/api-overview-market-data) * [Direct API categories](/reference/direct/direct-providers/overview) * [JSON-RPC overview](/reference/unified-api/overview-jsonrpc) * [Analytics & Logs](/guides/uniblock/uniblock-analytics) # Gaming and In-App Assets Source: https://docs.uniblock.dev/guides/use-cases/gaming-and-in-app-assets Use Uniblock to track player wallets, NFT item ownership, token rewards, and gameplay-related on-chain activity in games and in-app economies. Games and consumer apps often need a fast asset layer more than they need chain-specific infrastructure. Uniblock is useful here because the same integration can expose fungible rewards, NFT inventory, transfer history, and event-driven updates across multiple chains. ## Best-fit workflows * Player inventory views * Reward token balance displays * NFT item ownership checks * Real-time notifications for item or reward transfers * Backend services that read contract state or submit transactions *** ## Recommended APIs * [Token API overview](/reference/unified-api/api-overview-token) * [NFT API overview](/reference/unified-api/api-overview-nft) * [Transaction API overview](/reference/unified-api/api-overview-transaction) * [Webhooks overview](/reference/webhook/webhooks-overview) * [JSON-RPC overview](/reference/unified-api/overview-jsonrpc) *** ## Suggested implementation flow ### 1. Build the player asset view Use token and NFT balance endpoints to show: * soft currency balances * premium token balances * inventory items and collectibles If players can own assets on multiple chains, normalize them into one account view in your backend. ### 2. Track gameplay-related movement Transfer and transaction endpoints are useful for: * reward claim history * marketplace purchases * item transfers between wallets * contract interactions tied to gameplay ### 3. Use webhooks for live state changes Games benefit from event-driven updates more than most app categories. Use webhooks to trigger: * inventory refreshes * reward claim confirmations * contract event processing for on-chain game logic ### 4. Use JSON-RPC for game-specific contract reads If your backend needs custom contract methods, use JSON-RPC for direct reads and writes while keeping the Unified API for account and asset views. *** ## Why this pattern works For most games, the hardest part is not a single chain integration. It is keeping asset state, user-facing balance views, and event processing coherent as the product grows. Uniblock reduces that surface area by giving you a single data layer for the read path. *** ## Common pitfalls Do not make the gameplay loop depend on a single polling endpoint. Use webhooks or queued refresh jobs for state changes that matter to the user experience. Separate display balances from execution-critical contract reads. Your UI can use normalized APIs while your write path can still use JSON-RPC where needed. *** ## Related docs * [Webhooks overview](/reference/webhook/webhooks-overview) * [Solana address activity webhook type](/reference/webhook/webhook-types/event-trigger-solana-address-activity) # NFT Marketplaces and Discovery Source: https://docs.uniblock.dev/guides/use-cases/nft-marketplaces-and-discovery Build NFT marketplaces, discovery feeds, and collection experiences with Uniblock NFT APIs, metadata endpoints, and real-time webhook events. Uniblock can cover most of the read-heavy data layer for NFT products: collection metadata, item metadata, wallet holdings, floor prices, sales, listings, and ownership. That makes it a practical fit for marketplace frontends, collector dashboards, and collection discovery tools. ## Best-fit workflows * Collection landing pages * NFT detail pages * Wallet ownership and portfolio views * Sales and floor-price monitors * Real-time event streams for transfers and contract events *** ## Recommended APIs * `GET /nft/collection-metadata` * `GET /nft/nft-in-collection` * `GET /nft/metadata` * `GET /nft/floor-price` * `GET /nft/sales` * `GET /nft/owners/nft` * `GET /nft/owners/contract` * `GET /nft/transfers` * `GET /nft/transfers/nft` Start from the [NFT API overview](/reference/unified-api/api-overview-nft) for endpoint coverage. *** ## Suggested implementation flow ### 1. Build the collection page At minimum, load: * collection metadata * a paginated list of NFTs in the collection * floor price * recent sales That gives you the baseline marketplace browsing experience. ### 2. Build the asset page For each NFT detail page, combine: * `GET /nft/metadata` * `GET /nft/transfers/nft` * `GET /nft/owners/nft` This gives you provenance, owner state, and transfer history. ### 3. Build the owner experience For user profiles and portfolio views, combine: * `GET /nft/balance` * `GET /nft/owned-collections` * token endpoints if the same app also shows fungible positions ### 4. Add event-driven updates Use contract-event webhooks or NFT-focused templates from the webhook flow to: * refresh collection activity feeds * notify on transfers * track popular contracts and major sales activity *** ## Where Direct API fits NFT products often need marketplace-specific or provider-specific capabilities. When the unified schema is not enough, use [Direct API](/reference/direct/direct-providers/overview) for deeper marketplace or provider integrations while keeping Unified API as the default read layer. *** ## Common pitfalls NFT metadata can change over time. Refresh metadata and floor-price data on separate schedules instead of treating them as equally fresh. Ownership for ERC-1155 assets can involve multiple holders. Do not model all NFT ownership as single-owner ERC-721 behavior. *** ## Related docs * [NFT API overview](/reference/unified-api/api-overview-nft) * [Webhook quickstart](/reference/webhook/webhook-quickstart) * [Contract event webhook type](/reference/webhook/webhook-types/event-trigger-contract-event) * [Address activity webhook type](/reference/webhook/webhook-types/event-trigger-address-activity) # Uniblock use cases: wallets, DeFi, NFTs, gaming, and DAOs Source: https://docs.uniblock.dev/guides/use-cases/overview Pick a Uniblock use-case guide for wallets, DeFi dashboards, NFT marketplaces, gaming, airdrops, DAOs, and token launch workflows across chains. The old use-cases page mixed current platform capabilities with older product references. This section replaces it with guides that map directly to what Uniblock documents today: Unified APIs, webhooks, JSON-RPC, Direct API access, analytics, and logs. Use these guides when you want a practical starting point for a specific product shape rather than a feature-by-feature overview. Aggregate balances, NFTs, transfers, and activity across chains. Build token, price, liquidity, and market monitoring workflows. Power collection pages, ownership views, floor-price tracking, and sales feeds. Track player assets, rewards, inventory changes, and game-related activity. Monitor claims, token movement, NFT distribution, and campaign health. Track treasury flows, governance token movement, and contract events. Support launch operations with pricing, holder, transfer, and event data. *** ## How to use these guides Each guide follows the same pattern: 1. Start with the product shape you are building. 2. Use the recommended APIs and webhook types for that workflow. 3. Validate the response shape in the API tester or JSON-RPC tester. 4. Move into production with your own API key and monitor usage in analytics and logs. If you are completely new to the platform, start with the [Uniblock Quickstart Guide](/guides/getting-started/uniblock-quickstart-guide) first. *** ## Shared building blocks * [Token API](/reference/unified-api/api-overview-token) for balances, metadata, transfers, allowances, and token activity * [NFT API](/reference/unified-api/api-overview-nft) for collection metadata, ownership, floor prices, sales, and transfers * [Transaction API](/reference/unified-api/api-overview-transaction) for wallet and block transaction history * [Market Data API](/reference/unified-api/api-overview-market-data) for price, volume, history, and trending data * [Webhooks](/reference/webhook/webhook-quickstart) for event-driven workflows * [JSON-RPC](/reference/unified-api/overview-jsonrpc) for lower-level node access when your app needs chain-native methods * [Direct API](/reference/direct/direct-providers/overview) when you need provider-specific functionality beyond the unified schema *** ## Next steps Create a project, get an API key, and make your first request. Learn how routing, normalization, and failover work across the platform. Monitor usage, request volume, and debug failed calls with detailed logs. # Token Launches and Monitoring Source: https://docs.uniblock.dev/guides/use-cases/token-launches-and-monitoring Support token launches with Uniblock pricing endpoints, holder and transfer tracking, real-time webhooks, and post-launch analytics dashboards. The older use-cases page described token creation and launch tooling that is not part of the current docs set. Today, the documented Uniblock fit for token launches is the data and monitoring layer around a launch: token metadata, balances, transfers, market data, transaction tracking, and event monitoring. ## Where Uniblock helps * Launch dashboards for internal teams * Public token pages with price and transfer activity * Holder and treasury monitoring after launch * Real-time alerts for important launch-related events *** ## Recommended APIs * [Token API overview](/reference/unified-api/api-overview-token) * [Market Data API overview](/reference/unified-api/api-overview-market-data) * [Transaction API overview](/reference/unified-api/api-overview-transaction) * [Webhooks quickstart](/reference/webhook/webhook-quickstart) Suggested starting endpoints: * `GET /token/metadata` * `GET /token/price` * `GET /token/transfers` * `GET /token/activity` * `GET /transactions` *** ## Suggested implementation flow ### 1. Launch the public token page Use token metadata and market-data endpoints to expose: * token basics * current price * recent performance * trending status where relevant ### 2. Monitor treasury and operational wallets Use token balances, activity, and transactions to watch: * deployer wallets * treasury wallets * liquidity or operational addresses ### 3. Track launch events in real time Set up webhooks to detect: * major transfer activity * contract events tied to token movement * important wallet interactions after launch ### 4. Use analytics and logs during launch week Traffic and operational load tend to spike around launches. Keep: * [Analytics & Logs](/guides/uniblock/uniblock-analytics) for throughput, request trends, and debugging *** ## Common pitfalls Uniblock can support launch monitoring, but token deployment and sale logic still belong to your own contracts and launch infrastructure. Separate public market views from operational monitoring. The read patterns, refresh intervals, and failure tolerance are usually different. *** ## Related docs * [Market Data API overview](/reference/unified-api/api-overview-market-data) * [Webhooks overview](/reference/webhook/webhooks-overview) * [Analytics & Logs](/guides/uniblock/uniblock-analytics) # Wallets and Portfolio Trackers Source: https://docs.uniblock.dev/guides/use-cases/wallets-and-portfolio-trackers Use Uniblock to build multi-chain wallet views, portfolio dashboards, token balance summaries, and per-address account activity feeds. Wallet products need one thing more than anything else: a consistent account view across many chains. Uniblock is a strong fit when you want token balances, NFT holdings, transfer history, and transaction activity without maintaining separate provider integrations per network. ## What to build with Uniblock * A wallet home screen with balances across supported chains * A portfolio tracker with token, NFT, and transaction views * A recent activity feed for sends, receives, swaps, and NFT transfers * Real-time alerts for monitored addresses using webhooks *** ## Recommended APIs * [Token API overview](/reference/unified-api/api-overview-token) for balances, metadata, transfers, allowances, and token activity * [NFT API overview](/reference/unified-api/api-overview-nft) for wallet holdings and collection-level enrichment * [Transaction API overview](/reference/unified-api/api-overview-transaction) for account history * [Webhook quickstart](/reference/webhook/webhook-quickstart) for real-time address monitoring *** ## Suggested implementation flow ### 1. Build the portfolio snapshot Start with token balances, NFT balances, and the latest transactions for a wallet address. That gives you the minimum useful wallet experience. ```bash theme={null} curl --location \ 'https://api.uniblock.dev/uni/v1/token/balance?chainId=1&walletAddress=0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb' \ --header 'x-api-key: YOUR_API_KEY' ``` ### 2. Add valuation and metadata Once balances load reliably, enrich those positions with: * `GET /token/metadata` * `GET /token/price` * `GET /nft/metadata` * `GET /nft/collection-metadata` This is the point where a plain balance checker becomes a portfolio tracker. ### 3. Layer in account activity Use the transaction and transfer endpoints to build an activity tab with clearer event labeling: * incoming and outgoing token transfers * NFT transfers * contract interactions * chain-specific transaction details ### 4. Add real-time updates For wallets with notifications, use address activity webhooks so the UI updates from events instead of repeated polling. Use webhooks for notifications and use Unified API reads for the canonical UI refresh after an event arrives. *** ## Where JSON-RPC fits Use [JSON-RPC](/reference/unified-api/overview-jsonrpc) when you need chain-native methods such as: * `eth_getBalance` for direct native balance checks * `eth_call` for contract state reads * `eth_sendRawTransaction` when your product also broadcasts signed transactions For most wallet dashboard views, the Unified API is the faster starting point. Use JSON-RPC when you need lower-level control. *** ## Monitoring and debugging When wallet traffic scales up, watch: * [Analytics & Logs](/guides/uniblock/uniblock-analytics) for usage patterns, request volume, and debugging * [Rate Limits](/guides/uniblock/error-codes#rate-limits) if the app performs aggressive polling *** ## Common pitfalls Avoid assuming all chains use the same address format. EVM and Solana addresses should be validated differently before you submit requests. Do not rely on price data alone for portfolio state. Keep balances and pricing as separate refresh layers so stale market data does not block balance updates. *** ## Related docs * [Token API overview](/reference/unified-api/api-overview-token) * [NFT API overview](/reference/unified-api/api-overview-nft) * [Transaction API overview](/reference/unified-api/api-overview-transaction) * [Authentication guide](/guides/uniblock/authentication) # Uniblock quickstart overview: from sign-up to first API call Source: https://docs.uniblock.dev/quickstart Get from Uniblock sign-up to your first API call in minutes.

The count above reflects unique API paths.* > **Learn more:** [Codex Documentation](https://docs.codex.io/reference) ## Prefix and Example **Prefix:** No prefix is required for Codex, an example URL will therefore look like: `https://api.uniblock.dev/direct/v1/Codex + /[Codex_endpoint]`. **Example Request:** ```bash theme={null} curl --request POST \ --url https://api.uniblock.dev/direct/v1/Codex/filterNftPoolCollections \ --header 'accept: application/json' \ --header 'x-api-key: YOUR_UNIBLOCK_API_KEY' ``` ## Request format: GraphQL over POST Codex's underlying API is GraphQL. Uniblock exposes each Codex query as a REST-style `POST` endpoint whose path segment matches the Codex operation name exactly. For example, batch pricing is `direct/v1/Codex/getTokenPrices`, not `tokenPrices`. Use the paths listed in the tables below. Every Codex endpoint accepts a standard GraphQL HTTP body with two fields: * `query`: the GraphQL document as a string, using the arguments and fields from the linked Codex reference page * `variables`: an object with values for any variables in the query (use `{}` if there are none) **Example:** Look up a single token with `direct/v1/Codex/token`, which takes an `input` object of `address` and `networkId`: ```bash theme={null} curl --request POST \ --url https://api.uniblock.dev/direct/v1/Codex/token \ --header 'Content-Type: application/json' \ --header 'x-api-key: YOUR_UNIBLOCK_API_KEY' \ --data '{ "query": "{ token(input: { address: \"0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2\", networkId: 1 }) { id address networkId name symbol decimals isScam } }", "variables": {} }' ``` Authenticate with your Uniblock API key in the `x-api-key` header. You do not need a Codex API key. The full schema for each query (arguments, response fields, network IDs) is documented on the linked Codex reference pages. ## DeFi ### POST | Path | Est.

Solana gRPC streaming carries account, transaction, slot, entry and block metadata updates over one long-lived connection. The wire schema is stock Yellowstone, also called Dragon's Mouth, at proto 12.5. There are no custom extensions, no added fields and no added methods, so any standard Yellowstone client connects unchanged and there is nothing proprietary to install. ## Access Solana gRPC streaming is available as an add-on. Onboarding runs through the Uniblock team: provisioning is handled per customer, and the endpoint and credential are issued during setup. Onboarding for the Solana gRPC add-on runs through the Uniblock team. ## Pricing Solana gRPC streaming is billed on data transferred, at \$50 USD per TB, with partial terabytes rounded up. Enterprise discounts are available. Replayed data is metered the same as live data, so a full-window catch-up bills like the equivalent live stream. Narrow filters and `accounts_data_slice` are the levers that reduce transferred volume. ## Connect ### Endpoint ```plaintext theme={null} https://solana-grpc.uniblock.dev ``` TCP 443, HTTP/2. One hostname serves both live and historical subscriptions. ### Authentication **Solana gRPC does not use the Uniblock API key.** Streaming traffic does not pass through the Uniblock HTTP gateway, and the credential is a dedicated token issued during onboarding. The `X-API-Key` header that authenticates the Unified API, the Unified JSON-RPC endpoint and the Direct APIs has no effect on this endpoint. The credential is a single bearer token carried in gRPC metadata under `x-token`. There is no mTLS, no basic auth, no signing step and no handshake exchange. Authorization is evaluated once, when the stream is established, and is not re-checked while a stream runs. The token is opaque, with no meaningful internal structure. An IP allow-list is available and is configured during onboarding. It is empty by default, so a token authenticates from any address unless addresses are added. ### TLS TLS only, on 443, against a public CA chain. No client certificate and no mTLS. The system trust store is sufficient. ```rust theme={null} GeyserGrpcClient::build_from_shared("https://solana-grpc.uniblock.dev")? .x_token(Some(""))? .tls_config(ClientTlsConfig::new().with_native_roots())? .connect().await? ``` ### Stubs and client libraries Stubs are generated from the upstream Yellowstone repository at [github.com/rpcpool/yellowstone-grpc](https://github.com/rpcpool/yellowstone-grpc). Uniblock distributes no `.proto` of its own. | File | Path in the upstream repository | | -------------------------------------- | --------------------------------------------------- | | Service and streaming messages | `yellowstone-grpc-proto/proto/geyser.proto` | | Transaction and block types it imports | `yellowstone-grpc-proto/proto/solana-storage.proto` | `geyser.proto` declares `package geyser` and imports `solana-storage.proto` publicly, so generating from `geyser.proto` alone pulls in both. Stubs generated from the earlier v11 protos are wire-identical across all 26 streaming messages and remain compatible. | Language | Client | | -------------------------- | ------------------------------------------------------------- | | Rust | crates `yellowstone-grpc-client` and `yellowstone-grpc-proto` | | Go | `examples/golang` in the upstream repository | | TypeScript, Python, others | `examples/` in the upstream repository | ## What streams Five update kinds are produced: **accounts, transactions, slots, entries and block metadata**, at `PROCESSED`, `CONFIRMED` or `FINALIZED`. Each update is delivered once. Slot status transitions and block metadata each arrive a single time per slot. Every update carries `filters`, the list of filter names that matched it, and `created_at`, a server-side `google.protobuf.Timestamp`. One update lists every filter name it matched, so a single message can satisfy more than one filter. **Two filters are accepted and never produce data.** `blocks` and `transactions_status` are validated and held on the subscription, and neither ever fires. A subscription using only those filters receives nothing and reports no error. `transactions` covers the transaction status case. `blocks_meta` combined with `transactions` covers the block case. ### Methods All eight RPCs are implemented. `Subscribe` is the bidirectional stream. The seven unary methods answer from the same data the stream is built on, so a client holding a stream reads a blockhash or a slot without opening a JSON-RPC connection. | Method | Kind | | --------------------- | -------------------- | | `Subscribe` | bidirectional stream | | `SubscribeReplayInfo` | unary | | `Ping` | unary | | `GetLatestBlockhash` | unary | | `GetBlockHeight` | unary | | `GetSlot` | unary | | `IsBlockhashValid` | unary | | `GetVersion` | unary | ## Filters Each filter map key is an independent entry. An update is delivered if **any** entry matches it fully, and within one entry every populated field must hold. Sub-filters belong to their own entry and never gate frames matched by a different entry. The consequence in practice: a subscription carrying thirty owner filters plus one narrow `memcmp` filter receives everything the thirty owners produce, plus the `memcmp` matches. The `memcmp` does not narrow the other thirty. Constraints that must apply together belong in a single entry. The map key is a label. It comes back in `filters` to tell streams apart and is never compared against chain data. The addresses do the matching. ### Transaction filters `SubscribeRequestFilterTransactions`: | Field | Semantics when set | | ------------------ | ---------------------------------------------- | | `vote` | delivered only if `is_vote` equals this | | `failed` | delivered only if the failure flag equals this | | `account_include` | the transaction touches at least one of these | | `account_exclude` | the transaction touches none of these | | `signature` | exact signature match | | `account_required` | the transaction touches every one of these | An unset field is not a constraint, and an empty list is the same as unset. Leaving every field unset is a wildcard that streams every transaction, which is permitted and is how a firehose subscription is expressed. `account_include` is an OR across addresses. `account_required` is the AND version, which suits pinning a program and pool pair. Vote transactions dominate the raw feed by volume, so `vote: false` and `failed: false` is the usual starting point. ### Account filters `SubscribeRequestFilterAccounts`: | Field | Semantics | | ------------------------ | ----------------------------------------------------------------------- | | `account` | match these account addresses | | `owner` | match accounts owned by these programs | | `filters` | repeated sub-filters, all of which must hold, maximum 4 | | `nonempty_txn_signature` | require, or require the absence of, an associated transaction signature | Sub-filters, from `SubscribeRequestFilterAccountsFilter`: | Sub-filter | Shape | Notes | | --------------------- | -------------------------------------------------- | -------------------------------- | | `memcmp` | `offset` plus one of `bytes`, `base58` or `base64` | data capped at 128 bytes decoded | | `datasize` | account data length in bytes | may appear once per entry | | `lamports` | one of `eq`, `ne`, `lt`, `gt` | `cmp` must be set | | `token_account_state` | SPL token account state | **not supported, rejected** | `memcmp` requires decoding account data and is the expensive one. `owner` or `datasize` as the first cut, with `memcmp` refining inside the same entry, costs less. ### Slot, entry and block metadata filters `SubscribeRequestFilterSlots` takes `filter_by_commitment`, which delivers only slot updates whose status matches the requested commitment, and `interslot_updates`, which controls whether the intermediate transitions arrive. `SubscribeRequestFilterEntry` and `SubscribeRequestFilterBlocksMeta` are empty messages, so a named entry subscribes to the whole kind. ### Encoding Pubkeys, owners, signatures and hashes are raw bytes on the wire. Filters are given as base58 strings. Forgetting to encode when logging and decode when filtering is the most common cause of a filter that matches nothing. ### Reducing payload size `accounts_data_slice` is a repeated `{offset, length}` on the request rather than on a filter. When present, account updates are re-encoded so `data` carries only the requested ranges. For a subscription watching one field in a large account layout this is the difference between kilobytes and tens of bytes per update, and it is the cheapest bandwidth reduction available. ### Cardinality limits Checked when a `SubscribeRequest` arrives, on live and historical subscriptions alike. Exceeding one ends the stream with `INVALID_ARGUMENT` and a message naming the limit. | Limit | Value | | ------------------------------ | --------------------------------------------------------------------------- | | Transaction filter entries | 64, counting `transactions` and `transactions_status` together | | Account filter entries | 64 | | Pubkeys per transaction filter | 100,000, across `account_include`, `account_exclude` and `account_required` | | Pubkeys per account filter | 100,000, across `account` and `owner` | | Sub-filters per account entry | 4 | | Wildcard subscriptions | Allowed, for both transactions and accounts | The 64 counts distinct named map keys rather than addresses, so one entry holding several thousand pubkeys is one entry. The 100,000 ceiling is theoretical, because a request that large exceeds the 4 MB message cap first. ### Rejection rather than silent widening An address that fails base58 decoding, a signature of the wrong length, a `lamports` sub-filter with no comparator, a `datasize` given twice, an oversized `memcmp` payload and an unsupported `token_account_state` all end the subscription with `INVALID_ARGUMENT` and a message naming the offending field and value. A filter entry that lost its only address constraint would be a wildcard over the whole kind, so the request fails rather than quietly turning a narrow subscription into a firehose. ### A worked request Non-vote, non-failed transactions touching two programs, plus slot updates: ```rust theme={null} SubscribeRequest { transactions: HashMap::from([ ( "pump-amm".to_string(), SubscribeRequestFilterTransactions { vote: Some(false), failed: Some(false), account_include: vec![ "pAMMBay6oceH9fJKBRHGP5D4bD4sWpmSwMn52FMfXEA".to_string(), ], ..Default::default() }, ), ( "raydium-v4".to_string(), SubscribeRequestFilterTransactions { vote: Some(false), failed: Some(false), account_include: vec![ "675kPX9MHTjS2zt1qfr1NYHuzeLXfQM9H24wFSUt1Mp8".to_string(), ], ..Default::default() }, ), ]), slots: HashMap::from([("slots".to_string(), SubscribeRequestFilterSlots::default())]), commitment: Some(CommitmentLevel::Processed as i32), ..Default::default() } ``` Updates arrive with `filters: ["pump-amm"]`, `filters: ["raydium-v4"]` or `filters: ["slots"]`. A transaction touching both programs lists both names. ## Commitment and slot status Commitment is set once per request through the `commitment` field and applies to the whole subscription. Three levels are accepted: `PROCESSED`, `CONFIRMED` and `FINALIZED`. Commitment promotion is buffered per slot rather than re-fetched, so a `CONFIRMED` or `FINALIZED` subscriber receives the same bytes the `PROCESSED` subscriber saw, promoted when the status transition arrives. A slot's fate is reported by `SubscribeUpdateSlot.status`: | Value | Meaning | | --------------------------- | --------------------------------- | | `SLOT_FIRST_SHRED_RECEIVED` | first shred seen | | `SLOT_CREATED_BANK` | bank created | | `SLOT_PROCESSED` | processed | | `SLOT_COMPLETED` | all shreds received | | `SLOT_CONFIRMED` | confirmed | | `SLOT_FINALIZED` | finalized, terminal | | `SLOT_DEAD` | abandoned, reason in `dead_error` | Slots are never retracted and a replaced slot is not re-sent. A fork-aware client follows these transitions, treats anything below `SLOT_FINALIZED` as provisional, and unwinds work built on a slot that reports `SLOT_DEAD`. `interslot_updates` on a slot filter delivers the intermediate transitions rather than only the commitment-level ones. Each status fires once per slot. ## Historical replay Replay is triggered by setting `from_slot` on a `SubscribeRequest`. It is field 11 of the stock upstream message, so no special client, no SDK and no separate endpoint is involved. The stream replays forward from that slot and tails into live on the same connection, with no second reconnect and no gap. | | Value | | -------------------------- | ---------------------- | | Retention window | 48 hours | | Concurrent replay sessions | 64 | | Catch-up rate | Capped at 10x realtime | `SubscribeReplayInfo` returns `first_available`, the oldest slot currently held. The window drifts above the 48 hour floor because pruning runs on a schedule rather than instantly, so `first_available` is the value to branch on in code and 48 hours is the figure to plan against. The 64 session limit applies per customer rather than across the platform. Beyond it, a new replay subscription receives `grpc-status: 8` and a retry message. Live subscriptions are never affected by replay load. **Account updates are not retained.** A `from_slot` subscription carrying an `accounts` filter returns nothing for the historical portion and begins delivering at the live edge. Transactions, entries, blocks and block metadata are retained. Every filter applies to replayed data exactly as it applies to live data. Addresses, owners, data size, lamports, the vote and failed flags, `memcmp` sub-filters and exact `signature` matching all behave identically on either path. A `from_slot` older than the retained window is rejected with `grpc-status: 11` and a message naming the oldest slot still held. The available window is read out of that message rather than by retrying the same slot, because a reconnect loop that always sets the same `from_slot` after a rejection spins forever. The 10x cap is a real constraint on catching up. A full day of history takes roughly two and a half hours to replay. A subscription that needs to be current quickly starts from a nearer `from_slot`. ## Limits and client behavior ### Message sizes | Direction | Limit | | ------------------------------------- | ---------- | | Client to server (`SubscribeRequest`) | 4 MB | | Server to client (`SubscribeUpdate`) | Not capped | A `SubscribeRequest` over 4 MB is rejected and the stream ends with a status rather than staying open. Because outbound messages are not capped, the binding constraint is the client's own decode limit. Most gRPC stacks default to 4 MB. A subscription covering large accounts or busy blocks raises `max_decoding_message_size` on the Yellowstone client builder rather than relying on that default. ### Subscriptions and connections One `SubscribeRequest` per stream, replaceable in place: sending another replaces the active filter without reconnecting. A request carrying only `ping` is not treated as a filter update. There is no per-credential connection cap, and `max_concurrent_streams` is unset, so subscriptions multiplex freely over one connection. ### Compression Compression is not enabled and not negotiated. The server advertises no accepted or sent encodings, so every stream is uncompressed protobuf regardless of what a client offers in `grpc-accept-encoding`. ### Keepalives A `SubscribeUpdate` carrying `UpdateOneof::Ping` arrives on every stream every 15 seconds, including idle ones, so a filtered subscription that matches nothing still survives NAT and load-balancer idle timeouts. It is a keepalive and does not count as data. Keepalives carry `created_at` like every other update, so staleness computed from that field needs no special case. There is no server-side idle timeout. A stream lives until the client ends it, the connection breaks, or the client falls behind. `Ping` and `Pong` also exist as a client-initiated pair: a `SubscribeRequest` carrying only `ping` with an id returns the same id as `SubscribeUpdatePong`. ### Falling behind **Drops are not signaled.** There is no dropped-message count, no gap marker and no error status. When a client cannot keep up, its queue fills, the server removes it, and the stream simply ends. A client that logs only gRPC errors sees nothing at all, so an unexpected clean end of stream means the client fell behind rather than a normal shutdown. Ordinary HTTP/2 flow control applies first. A slow reader stalls its own stream and affects neither other streams on its connection nor other subscribers. The stream closes only once the per-client queue fills and does not recover. Remedies, in the order they usually work: move processing off the thread that drains the stream, narrow the filter, apply `accounts_data_slice` to cut payload size, read faster. ### Resuming There is no server-side cursor. Consumption is not tracked, so a reconnect starts live unless the request asks for something else. Resumption is the client's decision, through `from_slot`: track the last slot processed, set `from_slot` to it on reconnect, and the stream replays forward and tails into live on the same connection. A client that does not need gap-free delivery reconnects with no `from_slot`. That path is cheaper and cannot fail on a retention boundary. `from_slot` resumption suits state reconciliation that genuinely cannot tolerate a hole. ## Errors and retries Rejections carry an HTTP status, a gRPC status code, an `x-error-code` header and a `grpc-message`. `x-error-code` is stable and unique per condition and is the field to branch on. The prose is not stable and is better displayed than matched. `grpc-message` is always ` (code: )`. | Condition | HTTP | `grpc-status` | `x-error-code` | Retry | | --------------------------------------------------------------------- | ---- | ------------- | ----------------------- | --------------------------------------------------- | | Token missing, invalid, expired, or from a non-allow-listed address | 401 | 16 | `UNAUTHENTICATED` | No | | Credentials could not be verified, authentication briefly unavailable | 500 | 13 | `AUTH_UNAVAILABLE` | Yes, backoff | | Too many distinct invalid credentials from this address | 429 | 8 | `AUTH_RATE_LIMITED` | Yes, once the block expires, with valid credentials | | Credential checking saturated, load being shed | 503 | 14 | `AUTH_BUSY` | Yes, backoff | | Not a gRPC request, wrong `content-type` | 415 | 3 | `INVALID_CONTENT_TYPE` | No | | No node currently available | 503 | 14 | `NO_CAPACITY` | Yes, backoff | | All nodes briefly out of service | 503 | 14 | `UPSTREAMS_UNAVAILABLE` | Yes, backoff | | Node did not complete the request | 502 | 14 | `UPSTREAM_ERROR` | Yes, backoff | `UNAUTHENTICATED` covers a missing token, an invalid one, an expired one and a disallowed source address under one code, so a report of it is checked against the IP allow-list as well as against the credential. `AUTH_RATE_LIMITED` counts distinct invalid credentials from one address rather than failed attempts. A client stuck in a reconnect loop with one stale or revoked token retries it indefinitely without being blocked, and keeps receiving `UNAUTHENTICATED`. It is a configuration error to surface rather than a transient to retry. Conditions raised on the streaming path carry a status and a message but no `x-error-code`: | Condition | `grpc-status` | Retry | | -------------------------------------------- | ------------------------- | --------------------------------------------------- | | Too many transaction filters, maximum 64 | 3 | No. Narrow the filter | | Too many account filters, maximum 64 | 3 | No | | Too many pubkeys, maximum 100,000 | 3 | No | | Malformed address, signature or sub-filter | 3 | No. The message names the offending field and value | | `SubscribeRequest` above 4 MB | 3 | No | | `from_slot` older than the retained window | 11 | No. Resubscribe from the slot named in the message | | Replay session capacity reached | 8 | Yes, backoff | | No `SubscribeRequest` within 30 s of opening | 1 | Yes | | Client fell behind and its queue filled | none, clean end of stream | Reconnect | | Connection dropped before the TLS handshake | none, connection failure | Yes, backoff | Both `OUT_OF_RANGE` wordings name the oldest retained slot, so parsing for `retained from` is more reliable than matching either string whole. ### Backoff Statuses 13 and 14 retry with exponential backoff starting at 100 ms, capped at 30 seconds, with jitter. That covers `AUTH_UNAVAILABLE`, `AUTH_BUSY`, `NO_CAPACITY`, `UPSTREAMS_UNAVAILABLE` and `UPSTREAM_ERROR`. Status 8 carrying the replay capacity message retries the same way, as does a bare connection failure. Retrying 16 or 3 without changing the credential or the request repeats the same failure. On 11, the available window is read out of the message and the subscription resumes from there. # debug_accountRange Source: https://docs.uniblock.dev/reference/jsonrpc/1/debug/debug-account-range POST https://api.uniblock.dev/uni/v1/json-rpc Returns the accounts within a specific key range for the given block state. ### Parameters Unique identifier for a blockchain network.
