How to fetch data from different sources on the internet with Rails 3?

I am coding an application where I want to fetch megavideo, spike,live video, youtube ,facebook, etc......so how can solve IS there any method in rails 3 ?

I looked everywhere on the net for a solution but it all seems very 开发者_开发知识库confusing too me. Do anyone know of a good, simple gem that I can use for remote APIs? It was so simple in PHP.

Thankful for all input!
