I'm pretty sure you can purchase more API calls.

However I want to make clear that those API calls are to Wolfram's servers for things like natural language parsing and data. You can write an APIFunction that does not use API calls, but just uses cloud credits to do computation.

I understand it can be confusing, but there is a difference between API calls to your CloudObjects and API calls from your CloudObjects.

Thank you for making this clear! :-)
