    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.

    The Fly.io GraphQL API provides a programmatic interface for managing Fly.io platform resources including
    applications, IP address allocations, organizations, and networking configuration. The endpoint is available at
    https://api.fly.io/graphql and includes an interactive GraphiQL explorer 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`.

    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.
