How to retrieve SCOM on boarded Entities and performance metric values against entities through SCOM REST APIs?

Hi,

I'm trying to retrieve SCOM on boarded Entities as well as performance metric values against entities through SCOM REST APIs

Ex:
Windows server 1 : Cpu utilization is 10%

Windows server 1 : Disk utilization is 20%

In that scenario We have found following Github project which provides the information we need.
project url : <https://github.com/ehrnst/System-Center-Operations-Manager-API>

end points :

API/Computer/Windows/{ComputerName}

API/Perf/{managedEntityId}

that has used SCOM SDK as well as db warehouse to complete the task.

But I need to do same using SCOM REST APIS. I have followed SCOM Official documentation but it didn't help. Anyone can help me on this?
