Fly Io

Fly.io Machines API

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.
