Can free plan use Open AI integration?

I am currently testing out the simple Answer a Question prompt using OpenAI Integration…
I have enter the Open AI key but not tied my credit card.
I am using a free plan of the glide pages to test and was shown this error.
I have checked, my quota has not yet exceed.
I am guessing i need to upgrade my plan?

That message is from OpenAI. They don’t have a free plan for the API, you need a credit card on file.
