Recently, Yelp added a new API, a Phone Search API. This allows the user to look up businesses by phone number. I just finished adding Phone Search API support to my yelpapi Python project. After looking around, none of the other Yelp v2.0 API implementations support the Phone Search API yet. It also appears as though all the other Yelp API implementations still rely on pre-defined classes to represent search results, so I’m sure it’ll be a while before they add support for the new API.
