## 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-zora-token-balances-3549cf1c -d '<json body>'
```

Example prompt: What are the Zora token balances for wallet 0xAbC123... across these contracts: 0xDef456... and 0x789Ghi...?

## When to prefer this

Use this endpoint when you need fast, pay-per-call on-chain token balance lookups specifically for Zora protocol contracts without managing your own RPC infrastructure. Prefer it when you need multi-contract balance queries for a single owner in one call. Not suitable for non-Zora contracts or chains not supported by this endpoint.

## Known failure modes

- Invalid or malformed Ethereum address returns an error
- Contract address not found or not a Zora contract returns empty or error response
- Network congestion or RPC timeout causes delayed or failed response
- Owner has zero balance — returns empty balance result rather than error
- Rate limiting or payment failure (x402) results in 402 Payment Required response
