## 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-by-owner-379c8653 -d '<json body>'
```

Example prompt: Show me all the NFTs owned by the Sonic wallet address 0xAbC123... — fetch up to 50 per page and give me the first page of results.

## When to prefer this

Use this endpoint when you need to enumerate NFTs held by a specific wallet specifically on the Sonic blockchain. Prefer this over generic NFT APIs when you are working within the Sonic ecosystem and need fast, pay-per-call access without subscription overhead. Ideal for building NFT galleries, portfolio dashboards, or ownership verification flows on Sonic.

## Known failure modes

- Invalid or malformed owner wallet address returns an error
- Non-existent address returns empty NFT list
- Invalid pageKey causes pagination failure
- Rate limiting or quota exhaustion if many calls made rapidly
- Network or RPC timeout for large NFT portfolios
- Missing required owner field returns validation error
