Geotags for search results are now being returned in the Search Records API. We're still updating the docs, but the field is called geo_co_ords and it returns a semicolon-separated list of lat,lng pairs.
You can even jump to a street view (drag the small orange humanoid from the top left onto the map pin) and see how things have changed.
