## 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-soneium-nft-by-owner-27eb1308 -d '<json body>'
```

Example prompt: Show me all the NFTs owned by the Soneium wallet address 0xAbC123...def, and return up to 20 results.

## When to prefer this

Use this endpoint when you need to enumerate all NFTs held by a specific wallet on the Soneium L2 network specifically. It is well-suited for portfolio views, airdrop eligibility checks, ownership verification, and building NFT dashboards for Soneium users. Prefer this over generic NFT APIs when you specifically need Soneium chain data and want pay-per-call pricing without a subscription.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Unsupported address format (e.g. non-EVM) causes a 400-level error
- No NFTs found for the address returns an empty array
- Invalid pageKey causes pagination to fail or restart
- Rate limits or payment issues return a 402 Payment Required response
- Network-specific outages on Soneium may cause timeouts or 5xx errors

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
