Funci,
Support for third party libraries is out of the scope of support we can offer. That being said I did do a couple quick tests with the API and was not able to get it to run effectively inside Mobione.
My suggestion would be to create a new folder inside your projects structure and place the html files to use the api there. You can then call that page from your app using a button or whoever you would like inside an InAppBrowser.
Hope this helps some.
