## 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-celo-nft-metadata-aae915b6 -d '<json body>'
```

Example prompt: Can you pull the metadata for token ID 42 from the Celo NFT contract at address 0x1234abcd... — I need the name, image, and any trait attributes it has on-chain.

## When to prefer this

Choose this endpoint when you specifically need NFT token metadata from the Celo blockchain (not Ethereum, Polygon, or other EVM chains). It is a pay-per-call, no-subscription option ideal for agents that need occasional or low-volume lookups without committing to a monthly plan. Prefer this over generic blockchain RPC calls when you want a clean, pre-parsed metadata response rather than raw contract ABI calls.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty response
- Token ID does not exist on the contract — may return null or 404-equivalent
- Contract is not an NFT contract (ERC-721/ERC-1155) — unexpected or malformed response
- Metadata URI is off-chain and unreachable — image or attributes may be missing
- Payment failure via x402 protocol blocks the request
- Celo network congestion or RPC downtime causes timeout

## 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 on-chain NFT metadata for the specified token, typically including token name, description, image URL, external URL, and a list of trait attributes (type/value pairs) as stored in or referenced by the smart contract on the Celo network.
