info:
  title: KrakenD Service Debug Health API
  description: The KrakenD Service API exposes built-in operational endpoints for health checking, debugging, and metrics collection on a running KrakenD API Gateway instance. The health endpoint (/__health) is enabled by default and returns the gateway status. The debug endpoint (/__debug) is available when the server is started with the -d flag or debug_endpoint is set to true. The extended metrics endpoint (/__stats) runs on a separate port and provides detailed runtime metrics when the telemetry/metrics extra_config is enabled.
