Limit of $18 in Playground

Why is there a limit of $18 in Playground, which I haven’t used, but I can’t check my prompts because it shows the following issue: 'You’ve reached your usage limit. See your usage dashboard and billing settings for more details. If you have further questions, please contact us through our help center at

Hi and welcome to the Developer Forum!

$18 was a grant amount offered many months ago as a trail for you to test the API functions out. That ended a long time ago, so your account will be showing an $18 now expired credit amount. If order to make use of the API you will need to add some credit to your account from the billing section with a credit/debit card.
