The accuracy of the estimated location, in meters. This represents the radius of a circle around the given location. If your Geolocation response shows a very high value in the accuracy field, the service may be geolocating based on the request IP, instead of WiFi points or cell towers. This can happen if no cell towers or access points are valid or recognized. To confirm that this is the issue, set considerIp to false in your request. If the response is a 404, you've confirmed that your wifiAccessPoints and cellTowers objects could not be geolocated.
