How this service works
NFT Metadata (ERC-721 / ERC-1155) (ethereum). NFT metadata for ERC-721 and ERC-1155: tokenURI resolved (IPFS, Arweave, data: URIs) and the JSON fetched and parsed, with a direct image URL. Any of 5 chains.
Output
Returns on-chain NFT metadata including the token name, token URI, image URL, description, and attribute/trait list as stored on the Ethereum blockchain for the specified contract address and token ID.
Example use cases
Verify NFT traits before purchase
“Before I buy it, can you fetch the on-chain metadata for token ID 1 of the Ethereum NFT contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D and tell me its attributes and rarity traits?”
Display NFT in portfolio dashboard
“I'm building a portfolio view — can you look up the metadata for Ethereum NFT contract 0x60E4d786628Fea6478F785A6d7e704777c86a7c6 token ID 1, including the image URL and all on-chain properties?”
Audit NFT collection metadata
“I need to audit our NFT drop — can you retrieve the on-chain metadata for token ID 1 at contract address 0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB on Ethereum and confirm what traits are stored?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/ethereum/nft-metadata/:address/1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-chain NFT metadata from Ethereum mainnet for a known contract address and token ID, especially when you need ERC-721 or ERC-1155 support in a single endpoint. Prefer this over generic blockchain explorers when you want structured metadata output suitable for agent consumption at a low per-call cost.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Token ID does not exist for the given contract, returning a not-found error
- Contract is not ERC-721 or ERC-1155 compliant, leading to failed metadata resolution
- Token URI points to off-chain storage (e.g. IPFS) that is unavailable, returning incomplete metadata
- Ethereum node latency or RPC errors causing timeouts
- Malformed contract address format returns a validation error
