Detects: jailbreak attempts, instruction overrides, role-play manipulation, goal hijacking (OWASP ASI01), tool misuse patterns (OWASP ASI02), hidden instructions embedded in data, and indirect injection via external content. Returns a confidence score, severity rating, specific patterns detected, and a clear recommendation — block, warn, or pass. Pay per scan via x402 protocol. USDC on Base. No API keys. No subscriptions. No human in the loop. Agents call it directly. MCP tool name: scanforinjection
