Overview - Uniblock Docs

Unified API’s primary goal is to provide users with a one stop place for integrating blockchain functionality into applications with reliability, latency, and cost in mind.

Remember to create your project & get your API-KEY through our Uniblock’s dashboard.

The provided endpoints in Unified API offer a variety of functionalities related to tokens (both fungible and non-fungible), and transactions, across multiple blockchains. The endpoints can be filtered by these categories:

Token API

These endpoints provide functionalities related to fungible tokens (like ERC20). You can retrieve metadata about a token, query a specific address’s balance, track token transactions, and query for token allowances. List of all our Unified Token endpoints.

Endpoint	Description
token/metadata	Get the metadata of an ERC20 Token.
token/balance	Get the token balances of an address.
token/balance/historical	Get the historical token balances of an address.
token/price	Get the USD price of a token.
token/price/historical	Get the historical USD price of a token.
token/transfers	Get the token transfers of an address.
token/allowances	Get the allowances of an address.
token/activity	Get the token activity of an address.

Market Data API

These endpoints deliver real-time and historical market data from multiple exchanges. Access information such as cryptocurrency price quotes, market capitalization, trading volumes, and exchange rate data. Essential for financial analyses and trading strategies. A list of Uniblock’s supported Market Data API endpoints.

Endpoint	Description
/market-data/price	Get real-time token prices using IDs, symbols, chain IDs, or token addresses, with optional currency selection and raw provider data.
/market-data/market-cap	Retrieve the current market capitalization of a token, with support for multiple currencies and optional raw provider data.
/market-data/24-hour-volume	Fetch a token’s 24-hour trading volume across supported providers and currencies, with optional raw, unnormalized data.
/market-data/history	Get historical snapshots of a token’s price, volume, and market cap at a specific date or timestamp, in your chosen currency.
/market-data/chart-range	Query price, volume, and market cap data for a token over a time range, suitable for generating charts over a selected period.
/market-data/chart-price-range	Get price series data for a token between two timestamps, with optional period-based granularity for charting.
/market-data/trending	List trending tokens based on criteria like gainers and losers, most searched, most visited, volume, or market cap.

NFT API

These endpoints are related to non-fungible tokens (NFTs, like ERC721 or ERC1155). These endpoints allow you to check the NFT balance of an address, retrieve detailed information about NFTs in a collection, track NFT transactions, and fetch metadata about NFTs or NFT collections. List of all NFT endpoints:

nft/floor-price	Returns the floor prices of a NFT collection by marketplace.
nft/is-nft-holder	This endpoint checks whether a wallet address holds a specific NFT or if a wallet address holds any NFT from a given collection. If tokenId is entered, the endpoint will check if the wallet address holds that exact NFT. While if tokenId is omitted, the endpoint will check if the wallet address holds any NFT from the entered collection.
nft/sales	Gets NFT sales that have happened through on-chain marketplaces.
nft/owned-collections	Gets all NFT contracts held by an owner address.
nft/top-sales	Get the highest valued transfers by a contract
nft/owners/nft	Get owner’s wallet address or all owners’ wallet addresses of a specific nft. Number of owners can be greater than 1 for ERC-1155 tokens, or 0 if the token is burned.
nft/owners/contract	Get list of wallet addresses owning one or more of the contract’s nfts.
nft/owners/collection-id	Get list of wallet addresses owning one or more of the contract’s nfts by collection ID.
