Reverse Engineered ChatGPT API

About The Project

This project can be used to integrate OpenAI's ChatGPT services into your python code. You can use this project to prompt ChatGPT for responses directly from python, without using an official API key.

This can be useful if you want to use ChatGPT API without a ChatGPT Plus account.

Inspiration

ChatGPT has an official API which can be used to interface your Python code to it, but it needs to be used with an API key. This API key can only be obtained if you have a ChatGPT Plus account, which requires $20/month (as of 05/11/2023). But you can use ChatGPT for free, using the ChatGPT web interface. This project aims to interface your code to ChatGPT web version so you can use ChatGPT in your Python code without using an API key.

How it works

ChatGPT web interface's requests have been reverse engineered, and directly integrated into Python requests. Hence, any requests made using this script is a simulated as a request made by a user directly on the website. Hence, it is free and needs no API key.

Built Using

Getting Started

Prerequisites

• Python >= 3.9

Installation

pip install re-gpt

Usage

Basic example

from re_gpt import SyncChatGPT

session_token = "__Secure-next-auth.session-token here"
conversation_id = None # conversation ID here

with SyncChatGPT(session_token=session_token) as chatgpt:
    prompt = input("Enter your prompt: ")

    if conversation_id:
        conversation = chatgpt.get_conversation(conversation_id)
    else:
        conversation = chatgpt.create_new_conversation()

    for message in conversation.chat(prompt):
        print(message["content"], flush=True, end="")

Basic async example

import asyncio
import sys

from re_gpt import AsyncChatGPT

session_token = "__Secure-next-auth.session-token here"
conversation_id = conversation_id = None # conversation ID here

if sys.version_info >= (3, 8) and sys.platform.lower().startswith("win"):
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

async def main():
    async with AsyncChatGPT(session_token=session_token) as chatgpt:
        prompt = input("Enter your prompt: ")

        if conversation_id:
            conversation = chatgpt.get_conversation(conversation_id)
        else:
            conversation = chatgpt.create_new_conversation()

        async for message in conversation.chat(prompt):
            print(message["content"], flush=True, end="")

if __name__ == "__main__":
    asyncio.run(main())

Obtaining The Session Token

1. Go to https://chat.openai.com/chat and log in or sign up.
2. Open the developer tools in your browser.
3. Go to the Application tab and open the Cookies section.
4. Copy the value for __Secure-next-auth.session-token and save it.

TODO

• [x] Add more examples
• [ ] Add better error handling
• [x] Implement a function to retrieve all ChatGPT chats
• [ ] Improve documentation
