According to Evans, the service will provide each created level in the game with a custom URL that players can send to friends or even advertise online -- opening up new, direct ways to publicize original stages. Evans explains, "Rather than going on forums and saying, 'Please search for my level,' you can just say, 'Here's a link.'" When other users go to that page's link, they'll be given the option to queue the download of the LBP level, which will appear in the game the next time they turn on their PlayStation 3.
In addition to things like leaderboards, photos, and comments, the portal will also offer an application programming interface (API), which can be used to create custom LBP-related applications. Evans cites examples of other APIs for websites like Flickr and Google Maps, and says it will be possible to use the LBP API to create a Google Maps page that details the locations of levels on Craft Earth. Evans says the portal and API are currently being beta tested, with a launch coming "as soon as possible."
