POST https://argusapi.repello.ai/scan/analyze-prompt
This is the internal / platform endpoint used by the ARGUS platform’s tracing and guardrail system. It analyzes a user-supplied prompt against the policies configured for the asset and returns a verdict.
Prefer the SDK endpoint POST /sdk/v1/analyze/prompt for direct integrations. The /scan endpoints are used by the platform tracing layer and, unlike the SDK endpoint, do not accept an inline policies array — only the asset’s configured policies are applied.
