Inth Consent API

  title: c15t Backend Consent API
  version: 2.1.0
  description: REST API for the c15t consent backend (@c15t/backend) that powers the c15t cookie banner, consent manager, and preference center. The same API runs whether self-hosted or used through the Inth (inth.com) managed platform. This specification was DERIVED faithfully from the published open-source Hono route handlers in packages/backend of github.com/c15t/c15t (the live runtime spec is generated by hono-openapi and served at /spec.json). Requests are authenticated with a Bearer API key; a subset of endpoints are public (init/status) and are called directly by the browser SDK.
