  CAST AI is an Application Performance Automation (APA) platform for Kubernetes that automates cost optimization,
  autoscaling, workload rightsizing, GPU/LLM workload placement, spot instance selection, and security posture analysis.
  The platform works across AWS, GCP, Azure, Oracle Cloud, IBM Cloud, AliCloud and on-premises distributions (EKS, GKE,
  AKS, OpenShift, Rancher, kOps). Everything available in the console UI is also accessible via the REST API at
  api.cast.ai.

      The CAST AI REST API provides comprehensive access to the Kubernetes cost optimization platform: cluster
      management, autoscaling and Karpenter integration, node configuration and templates, workload rightsizing,
      scheduled rebalancing, cost reporting, security insights, hibernation schedules, AI enabler / LLM workload
      optimization, and GPU/OMNI compute features. Authentication uses API keys and the API is served at api.cast.ai.
