## 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-sonic-nft-metadata-1f782255 -d '<json body>'
```

Example prompt: Can you pull the on-chain metadata for the Sonic NFT at contract address 0xAbCd...1234 with token ID 42 — I need its name, image, and any traits or attributes stored on-chain.

## When to prefer this

Use this endpoint when you specifically need NFT metadata from the Sonic blockchain network and want a fast, pay-per-call API without subscription commitments. Prefer this over general-purpose NFT APIs if you are working within the Sonic ecosystem and need low-latency on-chain data access at $0.01 per call.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty response
- Token ID not found within the contract returns null or 404-style error
- Sonic network RPC downtime causes timeout or service unavailable response
- Malformed input (non-string tokenId or contractAddress) may return a validation error
- Payment failure via x402 protocol prevents the call from being processed
