Example prompt: Can you check the risk level and transaction history for blockchain address 0x742d35Cc6634C0532925a3b8D4C9C6D8e9b3e2f1 — I want to know if it's flagged as high risk and how many transactions it has made?

## When to prefer this

Use this endpoint when you need to quickly assess the risk profile and on-chain activity history of a specific blockchain address, particularly for fraud detection, compliance checks, or due diligence on counterparty wallets.

## Known failure modes

- Invalid or malformed address format returns an error
- Address not found in database may return empty or default values
- Network timeout if the upstream blockchain data source is unavailable
- Rate limiting if too many requests are made in a short period
