How to get all properties on "GET_DEVICE" API

I want to use deviceExpert API "GET_DEVICE" API to get info about device.

Documentation says that " This API is for fetching the hardware and software properties of any device from DeviceExpert ", but i get only few attributes (
{192.168.112.1={MAKE=Cisco, LOCATION=Super-place, OS_TYPE=IOS, MODEL=1941, CREDENTIAL_SUPPLIED=true, OS_VERSION=15.1(3)T, SYSTEM_DESCRIPTION=Cisco IOS Software, C1900 So..., SERIES=1900, DEVICE_TYPE=Cisco IOS Router, STATUS=READY}}}
)

i would like to get the attribute values "MAC Address" and "End Of Support Date"
How can I do it ?
