NFT Marketplaces and Discovery

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
  • 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 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 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.
