# ChatGPT-to-API
Create a fake API using ChatGPT's website

> ## IMPORTANT
> You will not get free support for this repository. This was made for my own personal use and documentation will continue to be limited as I don't really need documentation. You will find more detailed documentation in the Chinese docs by a contributor.

**API endpoint: http://127.0.0.1:8080/v1/chat/completions.**

[中文文档（Chinese Docs）](https://github.com/acheong08/ChatGPT-to-API/blob/master/README_ZH.md)
## Setup
    
### Authentication

Access token and PUID(only for PLUS account) retrieval has been automated by [OpenAIAuth](https://github.com/acheong08/OpenAIAuth/) with account email & password.

`accounts.txt` - A list of accounts separated by new line 

Format:
```
email:password
...
```

All authenticated access tokens and PUID will store in `access_tokens.json`

Auto renew access tokens and PUID after 7 days

Caution! please use unblocked ip for authentication, first login to `https://chat.openai.com/` to check ip availability if you can.

### GPT-4 Model (Optional)

If you configured a PLUS account and use the GPT-4 model, a HAR file (`chat.openai.com.har`) is required to complete CAPTCHA verification

1. Use a chromium-based browser (Chrome, Edge) or Safari to login to `https://chat.openai.com/`, then open the browser developer tools (F12), and switch to the Network tab.

2. Create a new chat and select the GPT-4 model, ask a question at will, click the Export HAR button under the Network tab, export the file `chat.openai.com.har`

### API Authentication (Optional)

Custom API keys for this fake API, just like OpenAI api

`api_keys.txt` - A list of API keys separated by new line

Format:
```
sk-123456
88888888
...
```
