I'm using the traffic API and all my responses are coming back null.
Even in a browser, http://www.mapquestapi.com/traffic/v2/markets?key=[KEY] just displays a blank document, but changing the key actually gives me an error. I assume I'm using the key wrong. Should I be using the consumer key here or should I be using the secret to generate a token or something along those lines? I couldn't find any documentation on this but was probably not looking in the right place.
