    description: The Fly.io Machines API is a low-level REST interface for provisioning and managing Fly
      Machines, which are fast-booting virtual machines that run on Fly.io's global edge infrastructure.
      It provides endpoints for creating, starting, stopping, and destroying Machines, as well as managing
      Fly Apps, Fly Volumes, and TLS certificates. The API is accessible publicly at https://api.machines.dev
      or internally within the Fly.io private WireGuard network at http://_api.internal:4280.

      with schema introspection and documentation tabs accessible directly in the browser. Authentication
      requires an Authorization Bearer token, which can be obtained by running `flyctl auth token`.

    description: The Fly.io Extensions API is a provider-facing HTTP interface that enables third-party
      services to integrate with the Fly.io platform as extension providers. When a Fly.io user provisions
      an extension via the flyctl CLI, Fly.io forwards the provisioning request to the provider's API
      with details about the requesting organization, and the provider responds with environment variable
      configuration that is attached to the target application.
