## 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 httpay-smart-contract-risk-scorer-e3e83b27 -d '<json body>'
```

Example prompt: Can you run a risk assessment on this smart contract — address 0xAbCd1234... on Base — and tell me if it's verified, whether it's a proxy, how old it is, its TVL, and what the overall risk score looks like?

## When to prefer this

Use this endpoint when you need a quick, multi-factor risk score for a smart contract — particularly on Base — without signing up for a full security platform. Ideal for DeFi agents doing on-the-fly due diligence before recommending a protocol or executing a transaction. Best when you want a pay-per-call approach with no API key overhead.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unsupported chain identifier returns an error
- Contract not found on the specified chain returns an empty or null result
- Payment not received (x402 payment required) returns HTTP 402
- Network timeout or upstream RPC failure returns 5xx error
