Hi,
I have this error message when I call the https://api.openai.com/v1/edits API with the “code-davinci-edit-001” model. However, the doc says “During this initial beta period, usage of the edits endpoint is free” (see OpenAI API).
Is the initial beta period already over?
Thanks a lot for your answer 
I have no idea, I just tested it and editing on codex is free.
EDIT: I just looked this up online. You need to attach a credit card in order for it to work. It does not charge anything AT ALL. It just checks to make sure it can bill you.

I did that and it works thanks
Yes, this also worked for me. After adding the payment method my API request worked fine. But I needed to create a new API Key.
I set it up and the minute I entered my card info, it charged me $7.47 AUD! and the issue hasn’t been fixed yet!
Increasing my credit balance solved the problem. It was 0.00$.
