Example prompt: Can you run an AI security audit on this smart contract at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 and tell me if there are any vulnerabilities or red flags I should know about?

## When to prefer this

Use this endpoint when you need a quick AI-driven security review of a deployed smart contract and can pay a small USDC micropayment per call. Prefer this over manual review tools when speed and automation matter, especially for unknown or newly deployed contracts.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address not found on-chain returns empty or error response
- Payment not included or insufficient micropayment triggers 402 response
- Address belongs to an EOA rather than a contract
- Rate limiting or service unavailability returns 5xx error
