## How to call it through Zero

```sh
zero fetch --capability agentdiet-on-chain-risk-assessment-260bfc7a
```

Example prompt: Can you run an on-chain risk check on this wallet address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e and tell me if it has any suspicious flags or risk signals before I interact with it?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call on-chain risk scoring without a heavy compliance platform subscription. Best for DeFi agents, crypto trading bots, or compliance workflows that need real-time risk signals on wallet addresses or contract addresses, especially when paying via x402 USDC micropayments.

## Known failure modes

- Invalid or malformed blockchain address returns an error
- Unsupported chain or address format not recognized
- Address not yet indexed or too new to have on-chain history
- Rate limiting or payment failure via x402/USDC returns HTTP 402
- Timeout if on-chain data providers are slow to respond
