## 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 synapse-api-zora-nft-by-owner-lookup-5e0d36d6 -d '<json body>'
```

Example prompt: Can you pull up all the Zora NFTs owned by wallet 0x1234abcd...5678, and show me up to 20 results?

## When to prefer this

Use this endpoint when you need to enumerate all Zora protocol NFTs held by a specific wallet address, especially in portfolio dashboards, collector profile pages, or ownership verification flows. Prefer this over generic NFT APIs when Zora-specific data is required, or when you need paginated traversal of a wallet's Zora holdings with cost-effective pay-per-call pricing via x402.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unrecognized pageKey may cause pagination errors or reset
- limit set too high may result in timeouts or truncated results
- Wallet with no Zora NFTs returns an empty list
- Upstream Zora/indexer API downtime causes 5xx errors
- Payment not received (x402) causes request rejection
