 ## 📄 Q & A
 
-- How to get **free** API Key for testing?
-
-Well, If you're facing high cost of openAI API, you can try this method for testing,
-
-1. Join [Galaxy AI](https://discord.com/invite/zJAk5akk3d) Discord server.
-2. Visit the ``Commands`` channel.
-3. Use ``/generate`` command to generate your private API Key.
-4. Then, You have to replace the ``API_URL`` variable in config.py with value ``https://galaxyapi.onrender.com``, also put your **generated** API Key in the ``API`` variable.
-
-```python
-API_URL = "https://galaxyapi.onrender.com"
-API = "<your-generated-key-here>"
-```
-Alternatively, You can set these variables in **Environment**.
-
 - Why can't I use Google search?
 
 By default, DuckDuckGo search is provided. The official API for Google search needs to be applied for by the user. It can provide real-time information that GPT could not answer before, such as today's trending topics on Weibo, today's weather in a specific location, and the progress of a certain person or news event.
