The Fusio System API is the meta surface every Fusio instance exposes without configuration. It carries the discovery document at the root, the health check, the route table, and the specification generator that emits the instance's own OpenAPI, OpenRPC, TypeAPI and client SDK archives on demand. It is what makes a Fusio deployment self-describing: the contract is generated from the running instance rather than maintained beside it.
Every API here is available over the APIs.io API and to AI agents over MCP.
One button, every client — Claude, Cursor, VS Code and the rest.
