FOCUS (FinOps Open Cost and Usage Specification)

FOCUS, the FinOps Open Cost and Usage Specification, is an open standard maintained under the FinOps Foundation that normalizes cost and usage data across cloud, SaaS, data center, and other technology vendors. FOCUS defines a common data schema, a controlled vocabulary of column names, allowed values, and pricing attributes so that practitioners can apply a consistent set of FinOps practices regardless of which provider generated the underlying billing dataset. FOCUS is purely a data specification rather than a REST API; conforming providers expose exports of their billing data in the FOCUS format, and tooling consumes those exports against the published column library, data model, and validator.

FOCUS (FinOps Open Cost and Usage Specification) publishes 1 API on the APIs.io network. Tagged areas include Billing, Cost and Usage, FinOps, Open Standard, and Specification.

The FOCUS (FinOps Open Cost and Usage Specification) catalog on APIs.io includes 1 Spectral governance ruleset.

FOCUS (FinOps Open Cost and Usage Specification)’s developer surface includes documentation and 5 more developer resources.

  description: FOCUS defines a common normalized data schema for cloud and technology billing data. The specification is delivered
    as a set of normative documents and supporting artifacts (column library, requirements model, validator, Excel/CSV samples)
    rather than as a REST API. This entry tracks the specification itself and links to a JSON Schema representation of a single
    FOCUS-conformant billing record so that data consumers and integrators can validate individual rows produced by FOCUS-aligned
    exports.
