You can get the connection info from the Query Game API (
https://www.warzone.com/wiki/Query_game_API). 
However, that does require a paid membership, but if you have a few maps I and maybe some other members can get that data for you.
I'm not sure what you mean by territory cost, could you perhaps elaborate on that? 
Example of API:
