Google MyMaps requesting json issue

I have a question about google maps requesting. I'm using this query string for getting location informations perfectly :

http://maps.google.com/maps/api/geocode/json?latlng=" + latitude + "," + longitude + "&sensor=true

But i want to use myMaps future for getting special area information. Here is my special map and i'm drawing some area and give name it :

https://www.google.com/maps/d/viewer?hl=tr&authuser=0&mid=11In97WOd6VWB5Kc-jGTOcu8TNzs

is there any way to get name this place with my query if some one in this area? For example i want to use maps.google.com/maps/api query and if i'm in this place json give the drawing name for me?

Basicly if i'm in red point, i want to get Canberk name(in the left pannel) with this query : http://maps.google.com/maps/api/geocode/json?latlng=" + latitude + "," + longitude + "&sensor=true

If it is not possible, you know is there any api google or not ? Thanks so much.
