## 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-token-balances-56a1d65e -d '<json body>'
```

Example prompt: What are the Zora token balances for wallet 0xAbC...123? Also filter it to just these two contracts: 0xDEF...456 and 0x789...ABC.

## When to prefer this

Use this endpoint when you need on-chain Zora token balance data for a specific wallet address, especially when you want to filter results to particular contract addresses. Prefer this over generic blockchain balance APIs when Zora-specific token data is the target.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Invalid contract address in the array causes a failed lookup
- Wallet with no Zora tokens returns an empty balances array
- Network or upstream Zora API timeout causes a 5xx error
- Missing required 'owner' field causes a 400 validation error
