It's surely a sign of APIs growing up when enterprise vendors are building tools to utilize them. Business management solutions company SAP AG has a new solution that helps businesses and organizations gain insights into market trends and customer sentiment in real-time. The "SAP Rapid-Deployment Solution for Sentiment Intelligence with SAP HANA" loads text data from any Web Channel that has a publicly available API. Once the data is into its system, SAP's software takes over.
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).
