Overpass API how to get the bbox of the city (or from normal coordinates) for it?
I don’t understand at all where and how to determine this value (50.7,7.1,50.8,7.2);
node
["name"="Gielgen"]
(50.7,7.1,50.8,7.2);
outbody;
For example, you need to get For Kyiv.

Use google places autocomplete just make curl requests and that's it, the accuracy is very good there.
