Credits

This project started as an IRC discussion between Yuri Astrakhan, Tim Starling, and Daniel Kinzler. Tim gave a huge kick-start by implementing the very first property. Later, Yuri has implemented numerous queries and formats, and is currently maintaining this feature. As of July 1st, 2006, Query API receives over 275,000 requests per day.

Initially all of Query API code was developed using an excellent text editor Notepad , but on July 1st NuSphere kindly donated PhpED - an IDE for PHP with advanced debugging and profiling capabilities. I am very grateful to NuSphere for their support.
