## 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 kiteendpoints-ai-crypto-wallet-address-validator-9626efc8 -d '<json body>'
```

Example prompt: Can you check whether this wallet address is valid before I send funds to it? The address is 0x742d35Cc6634C0532925a3b844Bc454e4438f44e and it's supposed to be an Ethereum address.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use wallet address validation without integrating a full blockchain SDK. Ideal for agents handling payment flows, onboarding forms, or airdrop pipelines that need a lightweight sanity check on user-supplied addresses before committing funds or storing the address.

## Known failure modes

- Malformed or missing address input returns an error or invalid flag
- Unsupported blockchain network may yield indeterminate results
- Ambiguous address format (e.g. checksummed vs non-checksummed) may not be distinguished
- Service outage or upstream provider failure returns a 500 error
- Incorrect network specified for the address causes false negative validation
