To make gRPC API calls to Nebius AI Cloud services in your code, you can generate API clients from the Protocol Buffer specifications hosted on GitHub. The proto files come with a configuration file for Buf. To generate an API client by using the Buf CLI:
  1. Install the Buf CLI for macOS or Linux, for example, by using Homebrew: 
    brew install bufbuild/buf/buf
  2. Clone the Nebius AI Cloud API repository and go to the Nebius AI Cloud Buf configuration: 
    git clone https://github.com/nebius/api.git
cd api
cat buf.gen.yaml
  3. Edit the configuration to keep only the programming languages you support. For example, for Java only: 
    version: v2
plugins:
  - remote: buf.build/protocolbuffers/java
    out: gen/java
  - remote: buf.build/grpc/java
    out: gen/java
  4. To generate the client code, run the following command: 
    buf generate
  5. To get the generated client code, go to the gen/<language> directory. For example, if you generated a Java client, go to gen/java.
