yelp

Introduction

This egg provides an interface to the public Yelp API. Yelp is social database of customer reviews of restaurants and businesses. It also provides generalized lookup by phone number, geocode, or address across the United States, Canada, and Great Britain. All six Yelp APIs are supported along with a simply query mechanism for traversing the structured JSON query result. A valid Yelp YWSID is required to use this API. There is no charge for a YWSID, though queries are rate-limited and use is subject to Yelp's API Terms of Use.

Requirements

None.

The chicken-install tests require the test egg. Using -test with chicken-install also requires that a valid YWSID exist in ../../ywsid above the egg's temporary install directory. When fetched with chicken-install -r, simply create a file named ywsid in the parent directory with the following content:

(set-ywsid! "<your-personal-ywsid-goes-here>")
