YQL: More than just data
•
0 likes•1,749 views
This document discusses using YQL to find missing children data from an IP address. It describes making API calls to get location data from an IP, then using that to find the corresponding Yahoo! GeoID and state/country codes. This location data can then be used to search a missing children database and display information for local missing children on 404 error pages, helping to spread awareness. Code examples of implementing this in PHP are also provided.
