Google Geocoding API Error: OVER QUERY LIMIT
google-geocoder, google-geocoding-api, php
Solution
The Google Geocoding API has a daily limit, but it also limits the speed with which you can make requests. Put a `sleep(1)` call between geocode calls and you'll likely be fine (if not, try increasing it by a couple more seconds).
Problem
I am currently using the Google Geocoding API and using it very sparingly. The limit is 2500 queries per day and I am probably in the range of 20-50 at most. Then every so often in the past week I will get an OVER_QUERY_LIMIT error. I am only processing 1 address at a time and there are no loops or anything. It only geocodes once and send the lat/lng to a database and after that it will only be reference from the database. Can anyone tell me why I'm getting this error? ``` $request_url = "http://maps.googleapis.com/maps/api/geocode/xml?address=".$siteAddress."&sensor=true"; ``` This worked flawlessly for over a month of testing until about a week ago. I have a few pages that do the same thing but are only referenced at different times for different purposes. Here is all the code for the geocoding. ``` $request_url = "http://maps.googleapis.com/maps/api/geocode/xml?address=".$siteAddress."&sensor=true"; // the request URL you'll send to google to get back your XML feed $xml = simplexml_load_file($request_url) or die("url not loading");// XML request $status = $xml->status;// GET the request status as google's api can return several responses if ($status=="OK") { //request returned completed time to get lat / lang for storage $lat = $xml->result->geometry->location->lat; $long = $xml->result->geometry->location->lng; echo "latitude:$lat, longitude:$long <br>"; echo "$lat, $long <br>"; //spit out results or you can store them in a DB if you wish } if ($status=="ZERO_RESULTS") { //indicates that the geocode was successful but returned no results. This may occur if the geocode was passed a non-existent address or a latlng in a remote location. $errorcode = "ZERO RESULTS"; echo "ZERO RESULTS"; } if ($status=="OVER_QUERY_LIMIT") { //indicates that you are over your quota of geocode requests against the google api $errorcode = "Over Query Limit"; echo "Over Query Limit"; } if ($status=="REQUEST_DENIED") { //indicates that your request was denied, generally because of lack of a sensor parameter. $errorcode = "Request Denied"; echo "Request Denied"; } if ($status=="INVALID_REQUEST") { //generally indicates that the query (address or latlng) is missing. $errorcode = "Invalid Request"; echo "Invalid Request"; } ```
