But However, if you're willing to do a two-step process, you can first query by address to get coordinates (you can use the Nominatum API directly, or just use the **`search?query=`** method and pull the top result's coordiates from the redirected URL after the **`#map=`** string) and then construct a marker URL with the **mlat** and **mlon** parameters.
