Unfortunately, you can not use Online Maps API without a map.
If you just need to find the address, make a request to any geocoding web service (for example Google Geocoding API), and process the response.

I've just bought the Online Maps for Unity, i'm making a game for VIVE witch uses WRLD to show the city in 3d. I want the player to search an address, choose between the top results and get the latitude and longitude to changes his position on WRLD map. So i though about try to use the Online Maps to make the search. I've tried a lot of ways figure out how to only make the search using the online maps whitout showing an map, but i can't find how to do it because all demos and scripts ask for something to show the map (an texture os something).

Can anyone help?
