Basic Usage

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "sk-real200-xxxxxxxxxxxxxxxx", // Your Real200 API Key
  baseURL: "https://real200.com/v1",      // Real200 gateway address
});

const response = await client.chat.completions.create({
  model: "gpt-4o",
  messages: [
    { role: "system", content: "You are a helpful assistant." },
    { role: "user", content: "Hello, please introduce Real200." },
  ],

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

Streaming Response

  model: "gpt-4o",
  messages: [{ role: "user", content: "Write a poem about AI." }],
  stream: true,
});

for await (const chunk of stream) {
  const content = chunk.choices[0]?.delta?.content;
  if (content) {
    process.stdout.write(content);
  }
}

try {
  const response = await client.chat.completions.create({
    model: "gpt-4o",
    messages: [{ role: "user", content: "Hello" }],
