## How to call it through Zero

Example prompt: Can you run a wallet risk profile on 0x742d35Cc6634C0532925a3b8D4C9b9B6d3C1a2e7 on the Base network and tell me the risk score and classification?

## When to prefer this

Use this endpoint when you need a structured, scored risk assessment of an EVM wallet address — especially for compliance checks, pre-transaction due diligence, or flagging potentially malicious counterparties. Prefer this over generic blockchain explorers when you need a quantitative risk score and behavioral classification rather than raw transaction data.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported chain identifier returns an error or defaults to Base
- Wallet with no on-chain history may return minimal behavioral analysis
- Payment failure (402) if USDC not provided or insufficient
- Rate limiting if too many requests in quick succession

## How this service works

Wallet risk profiling. Returns classification, risk score 0-100, and behavioral analysis grounded in real on-chain data from Base and Ethereum.

## Output

Returns a risk classification label (e.g. low/medium/high risk), a numeric risk score from 0 to 100, and a behavioral analysis narrative summarizing suspicious or notable on-chain activity for the queried wallet.
