How this service works
Return the NFTs owned by a wallet address on a given network. Each row carries the collection name, contract address, token ID, image URL (where available), and ERC-721 vs ERC-1155 standard. Up to 100 per call - paginate with `pageKey` from the previous response.
Output
A paginated list of up to 100 NFT records, each containing collection name, contract address, token ID, image URL (if available), and token standard (ERC-721 or ERC-1155), plus a pageKey for fetching the next page if more results exist.
Example use cases
Example prompt
“Can you pull up all the NFTs owned by the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — I want to see the collection names, token IDs, and any images?”
Technical details
Endpoint
POSThttps://agent402.tools/api/nft-holdingsWhen to prefer
Use this endpoint when you need a comprehensive, paginated inventory of all NFTs held by a specific wallet across major EVM chains (Ethereum, Base, Polygon, Arbitrum, Optimism). Prefer this over on-chain RPC calls when you want structured metadata including images and collection names without manually querying each contract.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported network name returns a validation error
- pageKey from a different query or expired session may return no results or an error
- Wallet with zero NFTs returns an empty list
- Rate limiting or payment failure returns a 402 or 429 error
