Perimeter Detection

Which API should I use to implement perimeter detection using Zymkey 4i?

All zymbit features, including perimeter detection, are accessible through a single API, which is available in Python, C, C++ languages. Check it out here >

Thank you for the help Phil.
I have another doubt, I am using Zymkey 4i along with a Raspberry Pi and want to implement perimeter detection, what other hardware devices will I need?
I read that I need a USB cable, is there anything apart from that?
