800 Series Router support

Trying to understand the IOS software and different versions. Would like to programmatically access one of the cisco 880G series 4G LTE router to issue some commands.

•    Is this router can be use YANG Development kit .
•  understood that this router is IOS 15.X version but not IOS-XR. 
•    Are there any IOS-XR or NX-OS programmable 4G LTE routers .

The 880 series boxes will not run IOS-XR or NX-OS, and devices running IOS prior to IOS-XE 16.3.1 do not support NETCONF/YANG. They only support NETCONF 1.0, RFC 4741, and no YANG data models. The 880 series will not currently run IOS-XE 16.x.y.

In terms of NETCONF/YANG, you are out of luck, and you need to stick with things like NETCONF 1.0 or WSMA.
