Quickstart

Swap the base URL. Keep the client.

The integration change is mostly the endpoint and the key.

  • Keep the OpenAI SDK and the same request shape.
  • Point the client at `https://onekeymodels.com/v1`.

First request

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.ONEKEYMODELS_API_KEY,
  baseURL: "https://onekeymodels.com/v1"
});

const result = await client.responses.create({
  model: "gpt-4.1-mini",
  input: "Write a one-sentence product summary."
});

console.log(result.output_text);

Questions before signup

The usual questions, answered before you create a workspace.

Do I need to rewrite my OpenAI client?

Usually no. Keep your OpenAI-compatible client and update the base URL and API key.

Which route should I start with?

Start with Budget if you want the fastest test. Choose Business for a steadier default, and pick BYOK when you already manage your own provider keys.

Can I move to another route later?

Yes. The goal is to keep one familiar integration while letting your route evolve with cost, stability, or control needs.

How should I think about billing?

Billing follows the route you choose. The public site focuses on structure and fit rather than publishing one universal platform price.
