Spy Dialer API - Comments

Spy Dialer
Spy Dialer lets users identify missed calls and mystery numbers by going directly to any U.S. based cell phone's outgoing voicemail to hear whose cell phone it is. With the Spy Dialer API, users can integrate the service into their web site or application. The Spy Dialer API uses SOAP messaging with HTTP POST or GET methods for accepting requests and returns results via XML. Full documentation is available with registration.
