I just want to ask if what I want to do is allowed first. So for now I'll just explain what I wan to do with this API and ask if it's allowed.
My web app is a Google Maps Currency Converter application. I use Reverse Geocoding to get the name of a place through its lat and lng coordinates and pass that name to a function that returns a currency abbreviation. With Google's Geocoding service, I'm getting a "ZERO_RESULTS" status code when I try to use reverse geocoding on Kosovo, Western Sahara and Wake Island (I get an empty JSON object). What I want to do is to use MapQuest's Reverse Geocoding API in the case where I get that "ZERO_RESULTS" status code come up.
So yeah: is this allowed? Or should I not do this?
