  label: Kubecost Allocation API
  description: The Allocation API retrieves cost allocation information for any Kubernetes concept, such as cost by namespace,
    label, deployment, service, and more. It is directly integrated with the Kubecost ETL caching layer and CSV pipeline so
    it can scale for large clusters.
