Sure thing.

For in-app content delivered through our infrastructure, whether it's free or paid through Apple's in-app purchase, we charge $0.05/download.

An API call is made to our system when a person wants to download content. If it's a paid item, a receipt is included in that call and we then validate the receipt with Apple. After that, the application can download the content.
