## 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-0e650a30 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need a quick, pay-per-call wallet address validation without subscribing to a dedicated blockchain data service. Particularly useful for one-off checks before processing crypto payments or onboarding users' wallet addresses. At $0.05 per call, it's cost-effective for low-to-medium volume validation needs where setting up a full blockchain node or premium subscription is not justified.

## Known failure modes

- Missing or malformed address input returns an error
- Unsupported blockchain network type may yield inconclusive results
- Network timeouts from underlying validation service
- Invalid JSON body returns 400-level error
- Address from unrecognized chain may return false negative

## How this service works

## Output

Returns a result object indicating whether the provided wallet address is valid, including format correctness and potentially the detected blockchain network or address type. May include a boolean validity flag and details about any detected errors in the address format.
