There's a list of really useful Web APIs in wiki: http://wiki.roblox.com/index.php?title=Web_APIs
I'm just wondering can you use these in-game or do they have equivalent functions, events or anything such? Some of them are just images and easy to use, but "api.roblox.com"s don't seem to have a use. If you know a use for them or anything equivalent for even a part of them, please post as an answer or comment.
Thanks,
SwaggyDuckie

The stuff on http://api.roblox.com/docs can be used for things such as getting a player's friends/groups lists, retrieving group information, and asset/asset management info. It can also be used for more complex things such as creating a bot to perform various automated tasks on the roblox website.
But how to use it from ROBLOX Studio?
Because it's a roblox domain, api.roblox.com can't be used with HttpService. So, you need to either use a proxy for it or handle retrieval all of the information on a server of your own.
Just what I'm looking for. Thanks!
