Restate Admin API
The Restate Admin API is the HTTP control plane for a running Restate Server, exposed by default on port 9070. It manages service deployment registration, lists and introspects services and handlers, controls invocations (cancel, kill, pause, resume, restart, purge), manages Kafka and event subscriptions, queries system state via embedded SQL, and reports cluster health and version. The Admin API is the surface the Restate CLI and Web UI drive, and an OpenAPI document for the running server is available at the /openapi endpoint.
