the pricing specifies daily usage but i received an email stating the following:

"Your business must be doing well! At this time you have consumed all of the allocated API calls under your PRO subscription to the Recipe - Food - Nutrition API.

If you continue to make calls this month, you will incur overage fees. We strongly recommend that you upgrade to a pricing plan with a higher quota."

Which seems to specify monthly limits, not daily.

Can you please advise as to specifically how the billing works? Am I for example, allotted 500 per requests per day with Pro, or 500 per month? I find it very had to believe that i have exceeded 15,000 requests in less than three days while just doing local testing of a project of mine.

Thank you for the help.
