OpenAPI Specification

openapi: 3.2.0
info:
  title: Den Admin Worker Activity API
  description: 'OpenAPI spec for the Den control plane API.


    Authentication:

    - Use `Authorization: Bearer <session-token>` for user-authenticated routes that require a Den session.

    - Use `x-api-key: <den-api-key>` for API-key-authenticated routes that accept organization API keys.

    - Public routes like health and documentation do not require authentication.


    Swagger tip: use the security schemes in the Authorize dialog to set either `bearerAuth` or `denApiKey` before trying protected endpoints.'
