Connect OpenAI Node SDK

Updated 2026-09-23

The official Node SDK; only baseURL and apiKey change.

Use cases

Good for calling models from Node.js servers. The official SDK needs only baseURL and apiKey changed. Do not use it directly in the browser, or visitors will see your key.

Tips

Read the key from a server-side environment variable; never commit it or ship it in frontend bundles.

If it cannot connect

1. Use https://omnimodel.me/v1 as the API host, without /chat/completions.
2. The key starts with key_ and is not paused or revoked; auth.invalid_key means the key cannot be used.
3. The model ID matches the catalog and is in the key's allowed models.
4. billing.insufficient_credit means the balance is too low; see common errors for more.

Setup

1. Install the dependency: npm install openai.
2. Point baseURL at the API host below and pass your own key.
3. Never ship the key to a browser; proxy the call through your own backend.

Settings

• API host：https://omnimodel.me/v1
• API key：YOUR_API_KEY
• Model：MODEL_ID

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "YOUR_API_KEY",
  baseURL: "https://omnimodel.me/v1",
});

const resp = await client.chat.completions.create({
  model: "MODEL_ID",
  messages: [{ role: "user", content: "你好" }],
});
console.log(resp.choices[0].message.content);
