With a valid key I still get errors.

read the returning message it says I exceeded my daily quota, checked my account, my free API trial period ended a few months back.

Paying for ChatGPI does not mean you can get API access, in short, you need pay for API access separately after a short trial period to use this tool:

"No, the ChatGPT API and ChatGPT Plus subscription are billed separately. The API has its own pricing, which can be found at https://openai.com/pricing. The ChatGPT Plus subscription covers usage on chat.openai.com only and costs $20/month."
