How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns NFT metadata for the specified token on World Chain, typically including the token name, description, image URL, animation URL, external URL, and an array of trait/attribute key-value pairs as stored on-chain or in the token URI.
Example use cases
NFT trait lookup before purchase
“Before I buy it, can you fetch the metadata for token ID 88 from the World Chain NFT contract 0x1a2b3c4d...? I want to check its rarity traits and image.”
NFT portfolio display enrichment
“I have a World Chain NFT — contract address 0xDeAdBeEf... and token ID 7 — can you grab its metadata so I can show the name, image, and attributes in my dashboard?”
Verify NFT authenticity and content
“Can you look up the on-chain metadata for token #512 on World Chain contract 0x9f8e7d... and tell me what name, description, and traits are stored on-chain?”

Endpoint
POSThttps://phantom-api-omega.vercel.app/api/worldchain/nft/metadataWhen to prefer
Use this endpoint when you need fast, pay-per-call NFT metadata retrieval specifically on the World Chain network without managing your own RPC infrastructure. Prefer it over generic blockchain RPC calls when you want a clean REST interface and are operating in a Web3 agent context that supports x402 micropayments.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Token ID does not exist within the contract (out-of-range) returns a not-found error
- Contract is not an NFT contract (no ERC-721/1155 metadata standard) may return malformed or empty data
- World Chain node unavailability causes timeout or 503 error
- Malformed input (missing tokenId or contractAddress) returns a 400 validation error
- Payment not fulfilled (x402 flow) results in 402 Payment Required response
