Getting more info about a resource

Hi,

could you please let me know what is the endpoint i can use to get detailed information about a resouce, for example if i have a virtual network "foo" then how do get the which address space and subnets are in that network , The api endpoint i can GET/POST so that i get this info. i would prefer the ARM endpoint , as i use that for provisioing too

Thanks in advance..
