Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability phantom-api-mantle-nft-metadata-a9d114d5 -d '<json body>'
```

Example prompt: Can you pull the metadata for token ID 1337 on Mantle NFT contract 0x1234abcd...? I want to see its name, image, and attributes.

## When to prefer this

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.

## Known failure modes

- 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

## 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).
