Perhaps a good API would return some coordinates plus a distance, to give an idea of the accuracy, and if the most likely location is on private property but there is a public place close to the most likely location within the probable region then return the nearest public place instead of the most likely location so as to avoid problems when incompetent users of the API inevitably ignore the accuracy number and send armed police to the given coordinates. In that case (South Pole, 1e6 km) or (Point Nemo, 1e6 km) would be a reasonable response when you have no idea of the location, and if some armed police freeze to death or drown, then diddums!
