Node.js example

npm install openai

export TOKENAIR_BASE_URL="https://api.tokenair.ai/v1"
export TOKENAIR_API_KEY="your_tokenair_api_key"

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.TOKENAIR_API_KEY,
  baseURL: process.env.TOKENAIR_BASE_URL,
});

async function main() {
  const completion = await client.chat.completions.create({
    model: "gpt-5-mini",
    messages: [
      { role: "system", content: "You write concise implementation notes." },
      { role: "user", content: "Give me a three-step API migration checklist." },
    ],
  });

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

main().catch((error) => {
  console.error(error);
  process.exit(1);
});

Run the file from a server-side Node.js environment. A successful response prints the assistant message. A 401 means the API key is missing or invalid; a model error usually means the model ID is not enabled for the account.
