  title: frp Client Admin API
  description: >-
    The frp client (frpc) exposes a built-in HTTP admin API on its local
    web server. The API lets operators inspect or hot-reload the client
    configuration, stop the client, query proxy and visitor status, and
    (when a configuration store is enabled) manage stored proxy and visitor
    definitions. All routes (except /healthz) require HTTP Basic
    authentication using the user and password configured in
    webServer.user and webServer.password.
