Example prompt: Can you run a risk check on the address 0x4e9ce36e442e55ecd9025b9a6e0d88485d628a67 on Base and tell me if it looks safe to send funds to?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call on-chain risk score for a specific wallet or contract address on Base, Arbitrum, or Solana. Prefer this over manual block explorer research when you need programmatic, structured risk signals for agent-driven workflows or DeFi transaction screening.

- Unsupported chain address format may yield no data
- Address not indexed yet may return limited or null risk data
