  title: Pangea Security Services AI Guard Secure Audit Log API
  description: Specification of representative Pangea security service APIs. Pangea exposes each security capability as its own REST service reachable at https://{service}.{csp}.{geo}.pangea.cloud (for example https://redact.aws.us.pangea.cloud). All requests are POST with a JSON body and are authenticated with a Bearer service token (or OAuth 2 access token) in the Authorization header. This document models several representative services - AuthN, Secure Audit Log, Redact, Vault, File Scan, IP Intel, Domain Intel, and AI Guard - and is not exhaustive of every endpoint or field.
