# Nebius AI Cloud API

Build client applications based on the gRPC API by Nebius AI Cloud. It enables you to automate resource management and send requests between your applications and Nebius AI Cloud services.

Besides interacting with the API directly, you can also use the following tools that are based on the API:

* [Nebius AI Cloud CLI](/cli/)
* [Terraform provider](/terraform-provider/)
* [SDK for Go](https://github.com/nebius/gosdk)
* [SDK for Python](https://github.com/nebius/pysdk)
* [SDK for JavaScript](https://github.com/nebius/js-sdk)

They facilitate the work with the API and serve as an alternative. For instance, you can use off-the-shelf libraries or declarative descriptions of resources instead of constructing API requests and parsing responses.
