If you don't already have an OpenAI account, first you need to go to https://platform.openai.com/ and click Sign Up or Log in if you already had an account.

After signing up, you will need to top up your credit to use the API key:

Go to your billing overview in your account settings

Click "Add payment details" and enter your payment details

Choose the initial amount of credits you want to purchase. The minimum purchase is $5.

‍After successfully setting up your paid account:

Click on API keys tab to create a new API key
