title: Most appropriate API for URL shortening service
body: <p>I've just finished an online service for shortening URLs (in php5 with Zend Framework); you can enter an URL and you get an short URL (like tinyurl and such sites).</p>
  
  <p>I'm thinking about the API for developers - at the moment you can send URLs with SOAP to the service, but I am not sure if this is a good solution. What is the best practice for such a service? REST? SOAP? Both?</p>
