- name: Oso Cloud Authorization API
  description: The Oso Cloud Authorization API provides REST endpoints for checking permissions, managing authorization facts,
    querying policies, and enforcing access control across applications and services. Core operations include authorize (boolean
    permission check), list (get authorized resources), actions (get allowed actions), query, and batch fact management. The
    API uses the Polar policy language for defining authorization logic and supports context facts for request-time data.
