Output
Returns a JSON object containing the NFT's collection name, symbol, owner wallet address, token standard (ERC-721 or ERC-1155), network, contract address, token ID, metadata URI (e.g. IPFS link), and a metadata object with name, description, image, and attributes if resolvable.
Example use cases
Verify NFT ownership before gating access
“I need to check who currently owns token #42 of the contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum — can you pull the owner address and collection name for me?”
Fetch NFT image and attributes for display
“Pull the metadata for token ID 500 from the Azuki contract 0xED5AF388653567Af2F388E6224dC7C4b3241C544 on Ethereum — I need the name, description, image URL, and traits so I can display them in my app.”
Identify NFT standard and metadata URI
“Can you look up token #10 from contract 0x495f947276749ce646f68ac8c248420045cb7b5e on Base and tell me whether it's ERC-721 or ERC-1155, along with the metadata URI?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/nft-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to look up on-chain NFT data for a specific token on EVM-compatible networks (Base, Ethereum, Arbitrum, Optimism, Polygon). It covers both ERC-721 and ERC-1155 standards and returns both on-chain info (owner, standard) and off-chain metadata in a single call, making it ideal for NFT verification, display, or enrichment workflows.
Side effects
- Invalid contract address returns an error or null fields
- Token ID not found on the specified network returns empty/null metadata
- Unsupported network other than base/ethereum/arbitrum/optimism/polygon returns a validation error
- IPFS metadata URI that cannot be resolved returns null for the metadata field
- Rate limiting or payment failure returns an HTTP 402 or 429 error
