New MapQuest OpenAPI
MapQuest has just released their OpenAPI for mapping and routing (press release here). Registration and details are at http://www.mapquest.com/features/main.adp?page=developer_tools_oapi
Of course, we registered and tried them. See their demos hosted here (popup window). To use them, you need an access key obtained after free registration (be careful to register exactly the domain name AND the folder where you want to use them, otherwise you'll get an invalid key error). You need to use this key in all requests from MapQuest.
Here's a simple demo (see it in popup window):

<body style="background-color:rgb(244, 246, 229)" id='body' >
<div id='myMap' class='myMap' style="height:400;width:300″>
</div><script type="text/javascript">
var mq = new MQMap("myMap");
var loc1 = new MQLocation();
loc1.setName("poi1″);
loc1.setAddress("1 Yonge Street");
loc1.setCity("Toronto");
loc1.setStateProvince("ON");
loc1.setPostalCode("M5E1W7″);
loc1.setCountry("CA");
loc1.setIconId(244);
mq.locations.add(loc1);
mq.setRolloverPopups(false);//To disable the popups
mq.getMap();
</script>
</body>
</html>
Don't forget to change your access key.
Good news is that you can use full addresses, not only geocodes.
Documentation and support forums are available after registration.
They are available for non-commercial use for 50,000 combined maps and geocodes and 5,000 routes per day. Business solutions are also available.
