## 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-monad-nft-metadata-lookup-db91080d -d '<json body>'
```

Example prompt: Can you pull the metadata for token ID 42 from the Monad NFT contract at 0xAbCd1234...5678? I want to see its name, image, and any traits.

## When to prefer this

Use this endpoint when you specifically need NFT metadata from the Monad blockchain network. Prefer it over generic EVM NFT APIs when the asset lives on Monad, and when you need fast, pay-per-call access without a subscription. Ideal for agents that need single-token lookups rather than bulk indexing.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Token ID does not exist on the contract — returns not found or null metadata
- Monad network RPC unavailability causes timeout or 5xx response
- Malformed input (missing contractAddress or tokenId) results in a 400 bad request
- Token URI points to unreachable or IPFS gateway that is offline — metadata may be incomplete

## 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 Monad token, typically including the token name, description, image URL, external URL, and an array of trait attributes (trait_type and value pairs) as stored on-chain or in the token URI.
