name: FOCUS (FinOps Open Cost and Usage Specification)
description: >-
  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.

    name: FOCUS (FinOps Open Cost and Usage Specification)
    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.
