Budget
Fastest low-cost entry for testing and early traffic.
Quickstart
One OpenAI-compatible API. Three routes.
Keep your client, switch the base URL, and choose the route that fits your cost, stability, or control needs.
No client rewriteRoute choice laterSame `/v1/*` shape
First request
Point your client at `/v1` and keep moving.
Send the first request quickly, then choose the route after you have seen it work.

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.ONEKEYMODELS_API_KEY,
baseURL: "https://onekeymodels.com/v1"
});
const response = await client.chat.completions.create({
model: "gpt-4.1-mini",
messages: [{ role: "user", content: "Say hello in one short sentence." }]
});

Questions teams usually ask
The common objections, answered in one place.
Do I need to change my OpenAI client?
Usually no. Keep your client, switch the base URL, and update the API key.
Which route should I start with?
Start with Budget for the fastest test, move to Business for a steadier production default, and choose BYOK when you want to use your own keys.
Can I move from Budget to Business later?
Yes. The public API shape stays familiar so you can start on one route and move later.
Where do I get access?
Create a workspace first. That gives you the place to manage access, docs, and your first request.
Ready to start?
Create a workspace and try the first request.
Get one workspace, send the first request, and decide the route after you see it working.
