Programmatically identify if an app is paid or free

Question

I would like to identify whether an app is paid or free; programmatically, at runtime.

To brief on the context I'm working on, I'm developing an SDK which can be used by various third-party apps. I would like to identify if the app that is using my SDK is paid or free.

Any suggestions to find this?

Answer 1

You should make them configure your SDK writing their app id somewhere, and then your SDK have to check the app store webservices like this

https://itunes.apple.com/lookup?id=theAppID

There you can check the price

Answer 2

One thing you can do is this

https://itunes.apple.com/lookup?id=YOUR_APP_ID

and then fetch price & currency values from the returned JSON
