  label: KEDA Metrics API
  description: KEDA's Metrics API scaler connects to an HTTP endpoint that exposes a numeric metric value, which KEDA uses
    to drive scaling decisions. The endpoint must return a JSON, Prometheus, XML, or YAML response containing a metric value
    at a configured path. KEDA polls the endpoint on a configurable interval and compares the extracted value against a threshold
    to determine the desired replica count for the target workload. This specification describes the interface that an external
    HTTP metrics endpoint must implement to be compatible with the KEDA Metrics API scaler.
