    description: >-
      The Fusio Backend API provides a REST interface to configure and manage
      all aspects of a Fusio API management instance. It covers operations,
      routes, schemas, actions, connections, apps, users, and marketplace
      resources used by the Fusio backend application.

    description: >-
      The Fusio Consumer API is used by the developer portal application and
      enables third-party developers to request access tokens, manage their
      apps, and interact with protected API endpoints. It provides the
      authentication and user management layer for API consumers.

    name: Fusio Worker API
    description: >-
      The Fusio Worker API enables executing API action logic in multiple
      programming languages by forwarding requests to external worker processes.
      Workers are implemented in the target language (JavaScript, Python, Java,
      PHP, etc.) and communicate with the Fusio core via a simple REST
      interface, enabling serverless deployments.
