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 the on-chain metadata for the specified NFT token on the Linea network, typically including token name, description, image URL, and an array of attributes/traits as stored in or linked from the smart contract.
Example use cases
NFT portfolio display enrichment
“I have a list of NFT token IDs from contract 0x1234abcd... on Linea — can you pull the metadata for token 101 so I can display its name, image, and traits in my app?”
Verify NFT rarity before purchase
“Before I buy token ID 7 from the Linea NFT collection at contract 0xDeAdBeEf..., can you pull its on-chain metadata so I can check its attributes and rarity traits?”
NFT provenance and ownership research
“I'm researching this Linea NFT — contract address 0xAaBbCcDd... token ID 55 — can you grab its metadata so I can see what the token actually represents and any properties attached to it?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/linea/nft/metadataWhen to prefer
Use this endpoint when you specifically need NFT metadata from the Linea blockchain network and want pay-per-call pricing without a subscription. Prefer over general-purpose blockchain explorers when you need programmatic, structured metadata output for a specific token. Ideal for agents that need to enrich NFT data on Linea without committing to a monthly API plan.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Token ID not found within the contract returns null or 404-style error
- Contract is not a standard NFT contract (ERC-721/ERC-1155) may cause metadata parse failure
- Linea network congestion or node unavailability causes timeout
- Malformed input (missing contractAddress or tokenId) returns validation error
- Off-chain metadata URI is unreachable causing incomplete metadata
