# How to setup various tokens and APIs for the project

This doc explains how to setup various tokens and APIs for the project. You will need some of these tokens and APIs to run the app and use its features. You must set up at least one of these tokens or APIs to run the app.

## OpenAI API key

To get your OpenAI API key, you need to:

- Go to https://platform.openai.com/account/api-keys
- Create an account or log in with your existing one
- Add a payment method to your account (this is not free, sorry 😬)
- Copy your secret key (sk-...) and save it in ./.env as OPENAI_API_KEY

## ChatGPT Free Access token

To get your Access token for ChatGPT 'Free Version', you need to:

- Go to https://chat.openai.com
- Create an account or log in with your existing one
- Visit https://chat.openai.com/api/auth/session
