The Protector Plus Guardrail Service API exposes two inspection endpoints — one for prompts (/input-check) and one for responses (/output-check) — plus an unauthenticated health probe.

  • On-prem — the hostname inside your network.

All API calls require an API key passed in the X-API-Key header. See Authentication.
