This project provides a simple web interface to check whether your OpenAI API key supports GPT-4 or other models like GPT-3.5-Turbo. It supports both single key checking and batch checking from a text file.

• Check if your OpenAI API Key supports GPT-4 and other models.
• Batch checking by uploading a text file containing multiple keys (this task is peformed by ChatGPT so you need to provide a working key if you need this feature).
• Simple and intuitive web interface.

The project is set up in Node.js with Express.js for the back-end and vanilla JavaScript for the front-end.

Ensure you have the following installed on your system:

1. Node.js (version 14 or higher)
2. npm (version 6 or higher)

To set up the project locally, follow the steps below:

1. Clone the repository:

git clone https://github.com/aikemist/openai-key-checker.git

2. Navigate into the project directory:

cd openai-key-checker

3. Install the project dependencies:

npm install

Create a .env file in the project root directory and add your OpenAI API Key (only needed by batch mode):

OPENAI_API_KEY=your_openai_api_key

To start the application:

npm start

This will start the server on port 3000 or the port specified in the PORT environment variable. Navigate to http://localhost:3000 to access the application.

• Single Key Check: Enter the API key in the input box and click "Check".
• Batch Key Check: Click "Batch", then select a text file containing one or more API keys.

• The server needs to be restarted after updating the .env file.
• The application uses OpenAI's models endpoint to check the available models for a key, and it also uses OpenAI's Chat API to preprocess the batch key text. Make sure the OpenAI API Key you use for server setup has the necessary permissions.
