Saturday is API Hackday. We love hackathons. Mmm. Can’t get enough. And at this one we are giving away a Sphero robot ball. To win it you need to build the best hack using the Ordr.in API. Some ideas below.  Go get ‘em:

— See food on Foodspotting, order it with Ordr.in.

— Group lunch ordering with Venmo

— Catering app connected to your meetup profile (never run out of pizza again!)

— Restaurant recommendation algorithm that suggests restaurants by number of checkings, positive yelp reviews, etc.
