How to access custom properties, set in Director, via API

Hi, I could not find this info elswere. Is it possible to GET custom variables via API? I want to include latitude and longitude of every host, and get it via API, to visualize the status on the map (leaflet.js for example). But I see no such variables via link v1/objects/hosts?host=screen1

The config preview:
object Host “screen1”
{ import “WinIOTscreens” display_name = “screen1” address = “”
vars.Address = “Street address”
vars.Latitude = "55.55555
vars.Longitude = “25.5555” }


object Endpoint “screen1”
{ host = “” log_duration = 0s }


object Zone “screen1”
{ parent = “master” endpoints = [ “screen1” ] }
