# Nebius AI Cloud REST API

The Nebius AI Cloud REST API provides programmatic access to the platform over standard HTTP/1.1 with JSON and provides a familiar way to interact with the Nebius AI Cloud API for teams that prefer plain REST over gRPC, SDKs, the CLI or Terraform.

## REST and gRPC

The REST API is generated from the same Protocol Buffer service definitions as the [gRPC API](/grpc-api/index), rather than maintained as a separate interface.

An API gateway translates HTTP/1.1 requests with a JSON body into the corresponding gRPC calls and converts the responses back to JSON. Because both interfaces share the same service definitions, they expose the same resources, operations and API versions.
