Food-sharing mobile photo app Foodspotting had an API since day one. Of course, every mobile app has an API, at least if it needs to store or retrieve non-trivial data. Most of those interfaces stay hidden away, private APIs with only that single, internal audience. Foodspotting, on the other hand, signed Zagat as an early partner and now also has OpenTable, among others, using its Foodspotting API. The company is not exactly making it widely available for any developer, though the documentation is public, planting it in a vast grey area that's becoming increasingly common.
Ordr.in founder and CEO, David Bloom, marks Ordr.in as the "Twilio for food." If that description fails to provide clarity, Ordr.in builds order and menu management tools for restaurants. Its API and enhanced toolkit (Hackfood) was announced and tested at Hackfood the Hackathon last week.
GoodGuide is a service that we have been using as a family for a while. It attempts to analyze a product holistically to produce a simple 1 to 10 rating of its 'goodness.' I am personally satisfied to see that the GoodGuide API will share this data with the world. Many consumers would love to choose products based on their total “goodness” but how can you possibly investigate all the companies and products that are out there?
