SDK Setup — OneHub

OneHub is OpenAI-compatible, so any existing client just needs the base URL changed.

SDK Setup

Because OneHub speaks the OpenAI wire format, you keep your existing tooling. Only two things change: the baseURL (or baseURL equivalent) and the API key.

OpenAI Node.js SDK

npm install openai

import OpenAI from "openai";

const openai = new OpenAI({
  baseURL: "https://www.onehub.design/v1",
  apiKey: "sk-onehub-xxx",
});

const completion = await openai.chat.completions.create({
  model: "openai/gpt-5-nano",
  messages: [{ role: "user", content: "Hello!" }],
});

console.log(completion.choices[0].message.content);

Python (openai package)

pip install openai

from openai import OpenAI

client = OpenAI(
    base_url="https://www.onehub.design/v1",
    api_key="sk-onehub-xxx",
)

resp = client.chat.completions.create(
    model="openai/gpt-5-nano",
    messages=[{"role": "user", "content": "Hello!"}],
)

print(resp.choices[0].message.content)

Browser (fetch)

const response = await fetch("https://www.onehub.design/v1/chat/completions", {
  method: "POST",
  headers: {
    "Authorization": "Bearer sk-onehub-xxx",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    model: "openai/gpt-5-nano",
    messages: [{ role: "user", content: "Hello!" }],
  }),
});

const data = await response.json();
console.log(data.choices[0].message.content);

Notes

Never hardcode keys in client-side code. Proxy through your own backend for production.
Streaming works with the same SDKs — pass stream: true; see Streaming.
