## How to call it through Zero

```sh
zero fetch --capability chainray-nft-token-metadata-lookup-fcf9e2f3
```

Example prompt: Can you look up the metadata and attributes for NFT token ID 1234 from contract address 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum?

## When to prefer this

Use this endpoint when you need on-chain NFT token-level metadata for a specific token ID and contract address. Prefer this over general blockchain explorers when you need structured, agent-ready JSON output across 46 supported chains with pay-per-request pricing and no subscription required.

## Known failure modes

- Invalid or non-existent contract address returns error
- Token ID not found or out of range for the collection
- Unsupported blockchain network specified
- Payment not fulfilled results in 402 response
- Contract address is not an NFT contract
- Network congestion may delay response
