Call the Responses API server-side using the OpenAI JavaScript SDK, and pull out the output.
Let's think about it this way for a moment
The official JavaScript SDK simplifies authentication, request formatting, and response parsing. If you put OPENAI_API_KEY in an environment variable, the SDK picks it up automatically. The example below uses gpt-5.6, the current model alias.
Let's connect this to everyday life
In a new project, run npm install openai and create the client from an ES module file. In production, you'll need to add try/catch, timeouts, logging, and user authentication.
Let's try it hands-on together
import OpenAI from "openai";
const client = new OpenAI();
const response = await client.responses.create({
model: "gpt-5.6",
input: "REST API ဆိုတာဘာလဲ မြန်မာလိုတိုတိုရှင်းပြပါ။",
});
console.log(response.output_text);An answer from the AI will appear in the terminal.5-minute try-it
Swap the input for a question you're curious about. Add a prompt to keep the answer under 150 words, and add error handling too.
A quick word of caution
Don't treat AI output as the final, guaranteed-correct answer. For anything important — critical facts, code, or user data — have a human review it before you use it.
