API Keys with Google Maps Geocoding
<p>I am using JQuery to get JSON data from the Google Maps Geodcode API using:</p>

<pre><code>var jsonLtdLng="https://maps.googleapis.com/maps/api/geocode/json?address=Sydney&amp;key=MY-KEY";

$.getJSON(jsonLtdLng, function (data) {
    console.log(data);
});
</code></pre>

<p>The documentation says I require a Server API Key, but this is not server side code?</p>

<p>I tried making a Server API Key using my own routers IP address and it worked (but of course this is useless for any other users). I tried adding the web hosts IP and just got the error that the key is not authorised.</p>

<p>I know you can run it without a key for small quotas, but is that not advisable?</p>

<p>Would anyone know how to make this work? Do I have to do this in server side with PHP?</p>
