Hi,
We don’t restrict app to use the higher number of APIs from its quota. IT is just there would be additional charges for that. You can know your API calls from AppHQ management console.
Go to AppHQ -- > Billing & Metering , in this section you can view your last two weeks and four weeks API calls based on resource and operations.
We are adding your total API calls and monthly API calls in App DashBoard section also and would be up in next few days.
