  "categories": ["api_error"],
  "error": "API error 503: Service temporarily unavailable"
}

---

Scan Failure

Category to Action Mapping

Category	Default Action
prompt_injection	block
dlp_prompt	block
dlp_response	block (or mask)
url_filtering_*	block
toxic_content	block
db_security	block
malicious_code	block
agent_threat	block
