CloudZero

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.

CloudZero publishes 6 APIs on the APIs.io network, including Allocation Telemetry API, AnyCost API, Billing API, and 3 more. Tagged areas include Budgets, Cloud Cost Management, Cost Allocation, Cost Optimization, and FinOps.

The CloudZero catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

CloudZero’s developer surface includes authentication, developer portal, documentation, pricing, GitHub presence, privacy policy, engineering blog, and 10 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cloudzero: open an issue to ask a question, or submit a pull request to add artifacts.
