Example prompt: Can you check if this Ethereum wallet address 0xAbc123...def456 is safe to interact with — I want to know if it's flagged for any suspicious activity before I send funds.

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call risk signal for a specific crypto wallet or smart contract address across major EVM chains (Ethereum, BNB, Base, Arbitrum, Polygon, Avalanche, Optimism) without a subscription. Ideal for AI agents that need on-demand, point-in-time safety checks before executing transactions or approving smart contracts.

## Known failure modes

- Invalid or malformed address format returns an error
- Unsupported chain identifier causes a bad request
- Address not found or insufficient on-chain history may return empty or low-confidence signal
- Payment failure (insufficient USDC balance via x402) blocks the call
- Rate limiting or provider downtime returns a 5xx error

## How this service works
