Yahoo! Query Language
Yahoo! Query Language
Initially launched in October 2008 with access to Yahoo APIs,[2] February 2009 saw the addition of open data tables from third parties such as Google Reader, the Guardian, and The New York Times.[3] Some of these APIs still require an API key to access them. On April 29 of 2009, Yahoo introduced the capability to execute the tables of data built through YQL using JavaScript run on the company's servers for free.[3]. On January 3, 2019 Yahoo retired the YQL API service.
