OpenAI Java SDK from NordRouter

Add the current version com.openai:openai-java from the official repository, then create a client:

java

import com.openai.client.OpenAIClient;
import com.openai.client.okhttp.OpenAIOkHttpClient;
import com.openai.models.chat.completions.ChatCompletionCreateParams;

OpenAIClient client = OpenAIOkHttpClient.builder()
    .apiKey(System.getenv("NORDROUTER_API_KEY"))
    .baseUrl("https://nordrouter.com/v1")
    .build();

var params = ChatCompletionCreateParams.builder()
    .model("anthropic/claude-sonnet-4.6")
    .addUserMessage("Ответь: работает")
    .build();

var response = client.chat().completions().create(params);
System.out.println(response.choices().get(0).message().content().orElse(""));

Do not write the key in the source code or application.properties, which will end up in Git.

Official SDK:openai/openai-java.
