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 Mantle network, typically including the token name, description, image URI, and an array of attributes/traits as defined by the contract's metadata standard (ERC-721/ERC-1155).
Example use cases
NFT marketplace item display
“Fetch the metadata for token ID 88 on the Mantle contract 0xAbCd1234... so I can show the name, image, and traits on our marketplace listing page.”
NFT rarity and trait analysis
“Get the on-chain metadata for token 512 from the Mantle contract 0xDeadBeef... — I need the attributes and properties so I can analyze its rarity.”
Portfolio NFT details lookup
“Look up the details for the Mantle NFT I own — contract address is 0x9F8a... and the token ID is 200 — I want to see what it looks like and what traits it has.”

Endpoint
POSThttps://phantom-api-omega.vercel.app/api/mantle/nft/metadataWhen to prefer
Use this endpoint when you specifically need NFT metadata from the Mantle (MNT) network. Prefer it over generic NFT APIs when Mantle chain coverage is required and you want pay-per-call pricing via x402 without an API key subscription.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Token ID not minted or out of range returns a not-found error
- Mantle network RPC unavailability causes a timeout or 503 error
- Malformed input (non-hex contract address or non-numeric token ID) may return a 400 validation error
- NFT metadata stored off-chain (e.g. IPFS not pinned) may result in incomplete metadata
