# TechMobi Documentation

> One API key to access DeepSeek, Seedance, and other leading AI models — no Chinese phone number or local payment method required.

## What is TechMobi?

TechMobi is a unified AI gateway that gives developers outside China direct access to DeepSeek, Seedance, and other models that are otherwise difficult to reach. Everything is exposed through a single OpenAI-compatible endpoint, so you can switch in minutes without changing your existing code.

You don't need:

* A Chinese phone number
* A Chinese payment method
* Separate accounts for each model provider
* Any changes to your existing SDK setup

## OpenAI-compatible

Change `baseURL` and you're done. Everything else — streaming, function calling, the SDK — works exactly as before.

```typescript theme={null}
import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: 'sk-hub-your-key-here',
  baseURL: 'https://oss.chatgpttech.mobi/v1',
});
```
