How this service works
NFT lookup on Ethereum, Base, Polygon, Arbitrum or Optimism: collection name, symbol, standard and supply; with token_id also the current owner and resolved metadata (name, description, image, attributes) from IPFS/Arweave/HTTP.
Output
Returns collection-level data (name, symbol, token standard such as ERC-721 or ERC-1155, and total supply). When a token_id is provided, also returns the current on-chain owner address and fully resolved token metadata including name, description, image URL (resolved from IPFS, Arweave, or HTTP), and any attributes/traits.
Example use cases
Verify NFT ownership before access
“Check who currently owns token #7429 of the NFT contract 0x60E4d786628Fea6478F785A6d7e704777c86a7c6 on Ethereum — I need to confirm ownership before granting them access.”
Display NFT gallery details
“Get the name, image, description, and all attributes for token #88 from contract 0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB on Ethereum so I can show it in the gallery.”
Audit NFT collection supply and standard
“Look up the collection name, symbol, token standard, and total supply for the NFT contract 0x495f947276749Ce646f68AC8c248420045cb7b5e on Polygon.”
Technical details
Endpoint
GEThttps://agents.torbrooknews.com/v1/nft?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve NFT metadata, ownership, or collection details across major EVM-compatible chains without managing your own blockchain node or NFT indexing infrastructure. Ideal for agents that need to verify NFT ownership, display token attributes, or audit collection properties on Ethereum, Base, Polygon, Arbitrum, or Optimism. Supports IPFS and Arweave metadata resolution out of the box.
Side effects
- Invalid or non-existent contract address returns an error
- Unsupported chain name returns a validation error
- Token ID not found in collection returns an error or empty metadata
- IPFS/Arweave metadata resolution timeout or gateway unavailability may delay or fail metadata fetch
- Contract exists but is not an NFT standard (ERC-20 etc.) may return unexpected results
