CloudZero is a cloud cost intelligence and FinOps platform that automates the collection, allocation, and analysis of infrastructure spend to uncover waste and improve unit economics. The CloudZero API V2 is REST-oriented, uses API key authentication, and exposes endpoints for querying billing costs and dimensions, managing insights and budgets, sending unit metric and allocation telemetry, and ingesting cost data from any source via the AnyCost framework.
