## 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 chainray-security-check-on-chain-address-security-screening-68de3c4a
```

Example prompt: Run a security check on the address 0x742d35Cc6634C0532925a3b8D4C9b5A3bF1D7A9C on Ethereum — I want to know if it's flagged, blacklisted, or associated with any hacks or scams before I send funds to it.

## When to prefer this

Use this endpoint when you need to screen a specific blockchain address for security risks before executing a transaction, integrating a counterparty, or interacting with a smart contract. Prefer this over generic block explorers when you need structured, machine-readable risk signals suitable for agent decision-making.

## Known failure modes

- Invalid or malformed address format returns an error
- Unsupported chain identifier results in a 400 or 404 response
- Address not yet indexed on the chain returns no data or empty result
- Payment failure via x402 results in a 402 response and no data returned
- Network timeout for real-time chain queries
