IP there is an 'up and coming change to the geocoder' that might help

snippet:
And here's a real JSON output:
{"name":"-122.073212,37.400665","Status":{"code":
200,"request":"geocode"},"Placemark":[{"id":"p1","address":"Whisman
Elementary, United States","AddressDetails":{"Country":
{"CountryNameCode":"US","CountryName":"United States","AddressLine":
["Whisman Elementary"]},"Accuracy": 1},"ExtendedData":{"LatLonBox":
{"north":37.477838,"south":
37.391718,"east":-122.059105,"west":-122.115674}},"Point":
{"coordinates":[-122.072382,37.428434,0]}}
you can use the bottom left [sw] and top right [ne] to determine scale
and therefore zoom level.
Zoom 16 is a safe bet as default and override it, if the bounding box
is smaller.
Cities like Paris, Madrid go deeper.
