I was under the impression, perhaps wrongly, that with an API key I could access unlimited Nokia Map Tiles for an application I am building with the Leaflet mapping API.

I am able, for now, to grab tiles within a coordinate mapping application via the following URL


But this is obviously undocumented. Is there a documented URL to request XYZ tiles? Or is the API meant to request single 2D image tiles and never meant to be placed in a mapping application like I am doing?
