There is currently no built in "distance matrix" functionality in the API but you can achieve the same thing in one call.

All you do is create ask for routing information and add each point as a waypoint. So the route is A->B->A-C->A->D ... There is a limit of 25 way points so you can do this for 12 points in one call. This method gives you the real distance as well, not as the crow flies so even better.

Then you can walk through the route you get back and get the distances for each seperate leg you want.

Its a little bit of code work but not too difficault
