ProgrammableWeb's API directory now includes 35 restaurant APIs. These APIs can provide developers with tools such as food and drink deals, customer service, restaurant search, delivery, social recommendations, venue photos, reservations, e-commerce software, menu sharing, and much more.
After continued requests for access to more Yelp data, and additional API functionality, Yelp has launched a developer preview of a brand new API. The Yelp API was rebuilt from the ground up. Yelp envisions the new features, data, and architecture will simplify the developer experience.
