  title: Traefik Proxy REST Entrypoints TCP API
  description: 'The Traefik Proxy REST API provides read-only HTTP endpoints for inspecting the runtime configuration and state of a running Traefik instance. It exposes information about HTTP, TCP, and UDP routers, services, and middlewares, as well as entry points, raw dynamic configuration, the support-dump archive, and the current Traefik version. The API must be enabled in the Traefik static configuration (`api.insecure: true` for quick exploration, or by binding the `traefik` entrypoint behind an `IngressRoute` with `service: api@internal` for production) and should always be secured behind authentication before being exposed publicly. All endpoints listed here are mounted under the `/api` path prefix on the `traefik` entrypoint (default port 8080).'
