Calico Cloud Usage API is one of 7 APIs that [Tigera](https://apis.io/providers/tigera/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include FinOps, Usage, and Software-as-a-Service. The published artifact set on APIs.io includes API documentation and authentication docs.

A read-only REST API on the Calico Cloud SaaS management plane that returns the same vCPU usage and managed-cluster data shown on the Usage Metrics page, for capacity planning, FinOps and license-compliance workflows. Three documented datasets — contracts (start/end dates, vCPU hours, package, add-ons), summary (per-project vCPU totals and usage over time) and managed clusters (per-cluster usage rows, optional project filter, CSV output) — with startTime, endTime and granularity query parameters. Authentication is an organization-scoped read-only API key generated in the web console.
