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 on-chain NFT metadata for the specified token, typically including token name, description, image URL, external URL, and a list of trait attributes (type/value pairs) as stored in or referenced by the smart contract on the Celo network.
Example use cases
NFT collection item inspection
“Look up the on-chain metadata for token ID 101 from the Celo NFT contract 0xABCDEF1234567890 — I want to see its name, image, and all its traits.”
Verify NFT ownership attributes
“I need to check the attributes and description for token ID 7 on Celo contract address 0x9876FEDC — can you fetch the full metadata from the blockchain?”
NFT marketplace data enrichment
“Fetch the metadata for Celo NFT token number 250 at contract 0xDEADBEEF00001111 so I can display its image and properties in my app.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/celo/nft/metadataWhen to prefer
Choose this endpoint when you specifically need NFT token metadata from the Celo blockchain (not Ethereum, Polygon, or other EVM chains). It is a pay-per-call, no-subscription option ideal for agents that need occasional or low-volume lookups without committing to a monthly plan. Prefer this over generic blockchain RPC calls when you want a clean, pre-parsed metadata response rather than raw contract ABI calls.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Token ID does not exist on the contract — may return null or 404-equivalent
- Contract is not an NFT contract (ERC-721/ERC-1155) — unexpected or malformed response
- Metadata URI is off-chain and unreachable — image or attributes may be missing
- Payment failure via x402 protocol blocks the request
- Celo network congestion or RPC downtime causes timeout
