## 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 kihustle-ethereum-address-validator-6236d39e -d '<json body>'
```

Example prompt: Can you check if this Ethereum address is valid before I send funds to it: 0x742d35Cc6634C0532925a3b844Bc454e4438f44e?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.002 USDC) programmatic check on whether a string conforms to Ethereum address format before executing on-chain operations or storing wallet data. Prefer over client-side regex when you need a trusted, paid API signal for address validity in automated pipelines.

## Known failure modes

- Missing or empty address field returns an error
- Non-string input may cause a parsing failure
- Malformed JSON body may result in a 400 error
- Network timeout if server is unreachable
- Ambiguous response schema may not clearly distinguish invalid address from API error
