The Vantage API allows you to programmatically access your cost data and create cost resources, like Cost Reports, folders, and dashboards. Browse all API endpoints alphabetically in the left navigation menu. Each endpoint page features a **"Try it"** button at the top that opens an interactive API playground. Enter your [Vantage API token](/api/authentication) to test API calls directly from your browser. **Keep in mind that the playground makes real API calls to your Vantage account using your live Vantage data. Exercise caution when testing endpoints that create, modify, or delete Vantage resources.** The interactive API playground lets you test endpoints directly from your browser. In the video below, the user opens the API playground and enters their access token. As they fill in parameters on the left, the information populates in the request on the right. Click **Send** to complete the API call. *** ## Resources Get started with the Vantage API. Understand the API schema and how to call various endpoints. Learn how to authenticate and access the Vantage API. Create an API access token with Read and Write scopes enabled. Vantage Query Language (VQL) is a SQL-like language designed to filter cloud cost data. VQL provides a normalized schema across various cloud providers. Consult the Data Dictionary to view the normalized field names used to create VQL statements. Each provider that Vantage integrates with makes different fields available in their billing data. ## Libraries The `v2` API currently supports the following libraries. These libraries are officially maintained by Vantage and are auto-generated from the API specification. If you want to have your client added to the list, please email [support@vantage.sh](mailto:support@vantage.sh). * [Go](https://github.com/vantage-sh/vantage-go) * [Python](https://github.com/vantage-sh/vantage-python) * [TypeScript](https://github.com/vantage-sh/vantage-ts) ## OpenAPI Specifications The API provides both [OAS (Swagger) 2.0](https://swagger.io/specification/v2/) and [OpenAPI 3.0.1](https://swagger.io/specification/) specifications. You can use either specification to generate your own client libraries or to explore the API using tools like [Swagger UI](https://swagger.io/tools/swagger-ui/) or [Postman](https://www.postman.com/). * The Swagger 2.0 specification is available at [https://api.vantage.sh/v2/swagger.json](https://api.vantage.sh/v2/swagger.json). * The OpenAPI 3.0.1 specification is available at [https://api.vantage.sh/v2/oas\_v3.json](https://api.vantage.sh/v2/oas_v3.json).
