I need an AI API that works well with Node.js

If you want an AI API that works well with Node.js, the best default choice is usually:

OpenAI API

Why it’s a good fit:

• Excellent Node.js support
• Simple SDK and straightforward REST API
• Strong docs and examples
• Good for chat, text generation, embeddings, and more

Node.js example

import OpenAI from "openai";

const client = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });

const response = await client.responses.create({
  model: "gpt-4.1-mini",
  input: "Write a short welcome message for my app."
});

console.log(response.output_text);

Install

npm install openai

If you want, I can also recommend the best one based on your exact app — for example:
