The 500px Ruby wrapper by Chris Micacchi has been designed to interact easily with the API capabilities of search, retrieve, and upload photos. It aims to reuse HTTP connections. 500px is a community of photographers who can showcase their projects, discover new photography styles, and find royalty-free art.
