Kubecost APIs Overview

API Directory

This resource covers primary APIs across open source and commercial Kubecost products, and includes a directory to up-to-date API documentation articles.


The Allocation API is used by the Kubecost Allocation frontend and retrieves cost allocation information for any Kubernetes concept, e.g. cost by namespace, label, deployment, service, and more. This API is directly integrated with the Kubecost ETL caching layer and CSV pipeline so it can scale for large clusters.


The Assets API retrieves the backing cost data broken down by individual assets, e.g. node, disk, etc, and provides various aggregations of this data. Optionally provides the ability to integrate with external cloud assets.


The Audit API varifies cached data sources of Kubecost for validity of the data sources and processes through a series of tests.


Savings endpoints provide cost optimization insights. The following savings endpoints are available at http://<kubecost-address>/model/ENDPOINT:

Endpoint Brief description
/savings Provides cluster-level potential savings estimates based on specific savings opportunities available in other endpoints.
/savings/requestSizing Provides recommendations for setting container resource requests.
/projectDisks List orphaned disks.
/projectAddresses List orphaned IP addresses.
/savings/abandonedWorkloads List abandoned workloads based on network traffic.
/savings/clusterSizing Provides recommendations for sizing clusters (node types and quantities).
