Free trial users receive an initial credit of $18 that expires after three months and have a billing limit of $18. Once the trial period has passed, you can choose to enter billing information to continue your use of the API. If no billing information is entered you will still have login access, but will be unable to make any further API requests.
Paying users have a billing limit of $120 per month and can update limits on the billing page. To increase your quota beyond the $120 monthly billing limit, please fill out the quota increase request form.
