# Finout API V1

The Finout V1 API is the first generation of the Finout API, enabling you to integrate, analyze, and optimize your cloud expenses. With endpoints for cost insights, tagging, and more, the API empowers teams to automate workflows, track spending, and drive efficiency across their cloud environments.

V2 is the recommended API for all new integrations. Use V1 when you need APIs which are not yet available in V2.
