How can I search games by its platform?

For example, I wanna find all the games played on PS3, what would be the correct url?  
looks like this won't work! 
http://api.giantbomb.com/games/?api_key=myKey&platforms=playstation3    

@baboonworksfine: Greetings! For the platform filter to work you need to use the numerical identifier of said platform. You can find this in the URL of the actual page of said platform (PS3 = 88).

Going for a http://api.giantbomb.com/games/?api_key=myKey&platforms=88 should work! (so you have &platforms=88 )
