I have the situation where I only need the miles that a trip would be and I don't actually need the turn-by-turn directions. I need the miles that would be the result of turn-by-turn directions but not the directions themselves. I am currently using the API to obtain the turn-by-turn directions and then discarding everything except the total miles. This seems, to me, to be very inefficent to send me back a ton of bytes when all I need is a few.
Is there an API that would just return to me the total miles?
On a related note, my usage is sky rocketing because every query I am making MapQuest is geocoding before generating the directions. However, I am sending lat/lons in my request. I'm not sending addresses. I've already captured the lat/lon of every location and am only sending the lat/lons. What am I missing?
If anyone can help, it would be most appreciated.
