Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns on-chain NFT metadata for the specified token, typically including the token name, description, image URL, external links, and an array of traits/attributes defined by the smart contract.
Example use cases
Verify NFT traits before purchase
“Before I buy this NFT, can you fetch the metadata for token ID 7804 on contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D and tell me what traits and attributes it has?”
Build NFT collection display
“I'm building a gallery page — can you grab the metadata for token ID 1001 at contract address 0x60E4d786628Fea6478F785A6d7e704777c86a7c6 so I can get the image URL, name, and description?”
Audit NFT metadata for a listing
“I need to verify the on-chain metadata for token ID 3333 on contract 0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB — can you retrieve everything: name, image, attributes, and description?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/bob/nft/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call NFT metadata lookups without a subscription. Ideal for agents that need on-demand access to NFT details across multiple networks without committing to a monthly API plan. Prefer this over free public RPC calls when reliability and speed matter, and over heavier NFT indexing services when you only need single-token metadata.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Token ID not found on the specified contract
- Network or chain not supported
- Metadata stored off-chain (e.g., IPFS gateway timeout) may cause delays or failures
- Malformed input parameters result in validation errors
- Payment failure via x402 protocol blocks the request
