#21193AI Security Guard - Security Scanning for Autonomous AI Agentsinline registration

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 ($0.012

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
