What the NFT API gives you

Read NFT and multitoken collections across major EVM chains, resolve metadata, and verify ownership without stitching multiple indexers yourself.

Collection inventory

List ERC-721 and ERC-1155 tokens for up to 10 collection addresses per call, with optional metadata included in the response.

Rich metadata

Fetch resolved metadata (name, image, attributes) per token ID or pull collection-level details from a contract address.

Ownership checks

Enumerate owners for a collection or token, verify if a wallet holds a token, and load wallet-level NFT balances grouped by contract.
