Make Your First API Call

Make sure you have obtained an API Key and configured your environment variables, then choose a method to get started.

Python
cURL
Node.js
Java

Install the SDK

pip install openai

Make a call

from openai import OpenAI

client = OpenAI(
    api_key="your-api-key",  # or use the environment variable TURING_API_KEY
    base_url="https://live-turing.cn.llm.tcljd.com/api/v1",
)

response = client.chat.completions.create(
    model="turing/gpt-5.4-mini",
    messages=[
        {"role": "user", "content": "Hello, please introduce yourself in one sentence."}
    ],
)

print(response.choices[0].message.content)

curl https://live-turing.cn.llm.tcljd.com/api/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-api-key" \
  -d '{
    "model": "turing/gpt-5.4-mini",
    "messages": [
      {"role": "user", "content": "Hello, please introduce yourself in one sentence."}
    ]
  }'

Install the SDK

npm install openai

Make a call

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "your-api-key",  // or use the environment variable TURING_API_KEY
  baseURL: "https://live-turing.cn.llm.tcljd.com/api/v1",
});

const response = await client.chat.completions.create({
  model: "turing/gpt-5.4-mini",
  messages: [
    { role: "user", content: "Hello, please introduce yourself in one sentence." },
  ],
});

console.log(response.choices[0].message.content);

Add dependency (Maven)

<dependency>
  <groupId>com.openai</groupId>
  <artifactId>openai-java</artifactId>
  <version>4.35.0</version>
</dependency>

Make a call

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

OpenAIClient client = OpenAIOkHttpClient.builder()
    .apiKey("your-api-key")
    .baseUrl("https://live-turing.cn.llm.tcljd.com/api/v1")
    .build();

ChatCompletionCreateParams params = ChatCompletionCreateParams.builder()
    .model("turing/gpt-5.4-mini")
    .addUserMessage("Hello, please introduce yourself in one sentence.")
    .build();

ChatCompletion completion = client.chat().completions().create(params);
System.out.println(completion.choices().get(0).message().content().get());

Model Selection

The example uses turing/gpt-5.4-mini (best value for cost). You can browse the model list to select other models by provider, such as OpenAI, Claude, or Gemini.
