I'm trying to provide other map options besides *just* Google. Unfortunately a single HTTP query (e.g. location=123+main+street) only seems to be readily supported by Google.

I had no luck trying to find anything about embedding in the documentation and decided to email them directly:

> 
> The MapQuest business products
>  (<https://developer.mapquest.com/documentation/>) support both single
>  line input "location=1555+Blake+St+Denver+CO+80202+US" and the
>  advanced, 5-box method
>  ("street=1555+Blake+St&city=Denver&state=CO&postalCode=80202&country=US").
>  Our API and SDK also lets you add the mapping/geocoding/routing
>  functions to your site without embedding links to the consumer site at
>  www.MapQuest.com.

Okay, so `location=123+main+street` *should* be supported in theory. However no example was provided. So using the `iframe` URL from the more client-oriented approach I tried the following without luck:

<https://www.mapquest.com/embed/?location=1555+Blake+St+Denver+CO+80202+US>

That just shows the map of the US as a whole.

How do I get the single HTTP query `location` to work for MapQuest embedding?

Correct: `location=1555+Blake+St+Denver+CO+80202+US` (single HTTP query).

Incorrect: `street=1555+Blake+St&city=Denver` (multiple HTTP queries).
