API Authentication

OpenAI Hub provides a fully compatible API with the official OpenAI interface. Simply replace the Base URL with the OpenAI Hub address to seamlessly access all officially supported models and features. All parameters, request formats, and response structures stay in sync with OpenAI.

Important Notes

•API Keys are sensitive — never expose them in client-side code or public repositories
•If using the official OpenAI SDK, just set the base_url / baseURL parameter to switch
•All requests are encrypted via HTTPS for data security
•API call rates are subject to account quotas — use them wisely

Base URL

https://api.openai-hub.com/v1

Key Features

Fully compatible with the official OpenAI API format — no code changes needed
Supports ChatGPT, GPT-4, DALL·E, Whisper, TTS, and the entire model lineup
Also supports native-format calls for Claude, Gemini, and other third-party models
API parameters and response structures stay in real-time sync with OpenAI
Global acceleration nodes for low latency and high availability

Quick Start

1Get an API Key

After registering an OpenAI Hub account, create an API Key in the console. The key format is sk-xxxxxxxxxxxx — keep it safe and never share it.

2Replace the Base URL

Replace https://api.openai.com in your code with https://api.openai-hub.com/v1. No other code changes are needed.

3Set Request Headers

Add an Authorization header (Bearer sk-your-api-key) and Content-Type: application/json to every request.

4Make a Request

Use any HTTP client (curl, Python requests, Node.js fetch, etc.) to call the API — parameters are identical to OpenAI.

Code Example

Python

from openai import OpenAI

client = OpenAI(
    api_key="sk-your-hub-api-key",
    base_url="https://api.openai-hub.com/v1"  # Only change this line
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[
        {"role": "user", "content": "Hello!"}
    ]
)

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