## 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-d1de4aaf -d '<json body>'
```

Example prompt: Can you check if this is a valid Ethereum address before I send funds to it: 0x71C7656EC7ab88b098defB751B7401B5f6d8976F?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.002 USDC) programmatic check of an Ethereum address format before executing a blockchain transaction or storing a wallet address. Prefer this over manual regex checks when building automated Web3 workflows that require address hygiene.

## Known failure modes

- Missing or empty 'address' field returns an error
- Malformed JSON body may result in a 400-level error
- Ambiguous response schema makes it unclear if address is truly valid vs just processed
- Service may return 'success' for status regardless of address validity, reducing reliability
