Step 1: Get an API key

1

Sign in to the dashboard

Create an account or sign in at app.chatgpttech.mobi. New accounts receive $5 in free credits.
2

Create a key

Go to API Keys and click Create Key. Give it a name like my-first-key.
3

Save your key

Copy the full key value — it is only shown once. Keys follow the format sk-hub-xxxxxxxx. Store it somewhere safe before closing the dialog.

​
Step 2: Test in the Playground

  1. Open the Playground in the dashboard.
  2. Select a model from the dropdown, such as deepseek/deepseek-chat.
  3. Send a message and confirm you get a response.
The Playground draws from your account balance and requires no additional setup.

​
Step 3: Integrate with your app

Point your existing OpenAI SDK at the TechMobi gateway by updating apiKey and baseURL. Nothing else needs to change. 
import OpenAI from 'openai';

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

const response = await client.chat.completions.create({
  model: 'deepseek/deepseek-chat',
  messages: [{ role: 'user', content: 'Hello!' }],
});

console.log(response.choices[0].message.content);
The gateway is fully compatible with the OpenAI API spec. If you are already using the OpenAI SDK, swapping in apiKey and baseURL is all it takes.
