AI Security Guard - Security Scanning for Autonomous AI Agents

Agents process inputs they don't control: APIs, MCP tools, documents, web content, emails. Each is a potential attack surface. A February 2026 zero-click RCE via calendar invite proved even routine inputs can compromise agents. Five specialized detection experts analyze content before your agent processes it: pattern detection, intent drift analysis, semantic analysis, structure analysis, and code analysis across 8 languages. Covers prompt injection, credential exfiltration, data theft, code injection, social engineering, and 60+ attack patterns. POST /v1/guard with content + intent_contract. Returns verdict, confidence, findings, recommendations. Agent decides: proceed, constrain, escalate, or block. Privacy by design: No API keys (x402 cryptographic payments). Content deleted in 15 minutes. No training on customer data. Zero data retention on AI provider. Services: Content scanning ($0.0015-$0.024), Document analysis (PDF/DOCX), Preflight validation (~10ms), Follow-up Q&A ($0.0125), Security advisory ($0.01). Payment via USDC on Base/Ethereum.
