Calico Cloud Usage API

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.

  base_url_note: Tigera does not publish the Usage API host in public documentation. The console generates
    a ready-made command per API key ("Actions > Generate commands"), so the base URL is only visible
    to authenticated customers. Recorded without a baseURL rather than guessed.
