This is a Ruby wrapper for the Groupon API. It features activities to do in major cities. To use this library, developers need a key. Next, they can access 'listing divisions,' 'finding deals,' and 'finding deals by division.' Stephen St. Martin authored on GitHub. Copyrighted by Wynn Netherland.
Consumer Notebook just launched their API at PyCon. The Consumer Notebook site allows users take products and add them to lists and grids. Lists, as you’d expect, allow you to group common products. For example, gift ideas for friends, or books you’d like to buy. Grids provide a way to rank and compare a set of similar products. Perfect for planning your next cell phone upgrade, or deciding which trampoline best fits your lifestyle.
Consumer Notebook [is a] product comparison site that combines the best features of Open Comparison, Yelp, Consumer Reports, and Pinterest.
The API is REST based, and provides data in JSON format. Currently the documentation only references read access to the principle resources: Users, Products, Lists, and Grids (a comparison of products).
