## 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 crypto-wallet-address-validator-3df971e0 -d '<json body>'
```

Example prompt: Can you validate this crypto wallet address for me — 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — and tell me if it's a valid Ethereum address before I send funds to it?

## When to prefer this

Use this endpoint when you need to verify a cryptocurrency wallet address before initiating a transfer, storing an address, or displaying it to users — especially when correctness is critical to prevent irreversible fund loss. Prefer this over manual regex checks for multi-chain support.

## Known failure modes

- Invalid or malformed input address returns validation failure
- Unsupported blockchain address format may yield inconclusive result
- Empty or missing address field returns an error
- Network timeout or upstream service failure returns 5xx error
- Payment failure (insufficient USDC) returns 402 Payment Required
