## 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-83445778 -d '<json body>'
```

Example prompt: Can you validate this wallet address and tell me if it's correctly formatted before I send funds to it: 0x71C7656EC7ab88b098defB751B7401B5f6d8976F?

## When to prefer this

Use this endpoint when you need to programmatically verify that a crypto wallet address is valid and properly formatted before sending funds or storing address data, especially in a pay-per-call context where you only pay $0.14 USDC for occasional spot-checks rather than maintaining a full validation library.

## Known failure modes

- Invalid or malformed input address returns validation failure
- Unsupported blockchain address format may return inconclusive result
- Payment failure via x402/USDC results in 402 response blocking the call
- Network timeout returns server error
- Empty or missing address field returns schema validation error
