URL 変わっちゃうの申し訳ないんだけど、一覧性が高くなるのと pull req が受け取れるメリットのほうを取ります。せっかく読みにきてくれたのにひと手間かかっちゃってすみません。

Ruby の HTTP クライアントライブラリ Faraday が便利そう
API ラッパの開発には [RestClient gem][rest_client_gem] だとか
OAuth の必要なものは [Net/HTTP][net_http] + [OAuth gem][oauth_gem] を使ってた
[Twitter gem][twitter_gem] や [Instagram gem][instagram_gem] など API ライブラリのソースを読んでみると
[Faraday gem][faraday_gem] というものがよく使われてた
