## 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 webacy-risk-score-api-6c0dbece
```

Example prompt: Can you check the risk score for Ethereum wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on eth and tell me if there are any issues flagged?

## When to prefer this

Use this endpoint when you need a quick, per-address risk signal for a blockchain wallet on EVM-compatible chains or Solana. Prefer this over full contract analysis endpoints when the target is an EOA or when you need a lightweight risk score rather than deep contract source analysis. Choose this when building compliance gates, pre-transaction screening, or onboarding flows that require a pass/fail risk signal per wallet.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Unsupported chain identifier causes a bad request error
- Missing required 'chain' query parameter returns a validation error
- Payment failure (402) if x402 USDC payment is not included or insufficient
- Address not found on specified chain may return empty or null results
- Rate limiting or quota exceeded returns a 429 error
