Favatar is a favicon hosting service. Favicons graphically represent a webpageâ€™s hyperlink to users. With Favatar, web developers can retrieve permanent URLs for the favicons associate with their sites. The entire service is an API. Developers register for an API key and send requests including the URL of the website whose favicons they want accessed. Favatar will return an ordered list of all the icons it can find at the specified address. The Favatar API is REST-based and returns JSON and JSONP formatted data.
Favstar, a service that helps users "find great tweets and interesting people to follow", has announced that it will be shutting down next month because of changes Twitter is making to its APIs. Favstar's creator, Tim Haines, was left with no choice but to shut his service down due to API changes.
