-# The repo layout
+CloudBeaver and Team Edition communicate with their web browser frontends by exposing a GraphQL API. In some cases, users may want to leverage the same API to enable advanced use cases by automating certain operations usually done using UI. To explore the API, you can [use an embedded GraphiQL console](https://github.com/dbeaver/cloudbeaver/wiki/Server-API-explorer). You can look at the real examples of using the API in this repository.
