CAST AI
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.
CAST AI publishes 17 APIs on the APIs.io network, including AI Enabler API, Allocation Groups API, Autoscaler API, and 14 more. Tagged areas include Autoscaling, Cloud Infrastructure, Cost Optimization, DevOps, and FinOps.
The CAST AI catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
CAST AI’s developer surface includes authentication, documentation, getting-started guide, changelog, pricing, engineering blog, support, and 18 more developer resources.
