Kayak Explore monitoring

[newz12]

Do you know if there is a monitoring tool you can use to trigger alerts when a price drops in a specific area of the Kayak map? For example, to be warned if a ticket is falling under $350 in the North-American region (from your home city).

This would be incredibly helpful, since many fares that are shown on the map are expired... if we get the notification by e-mail right away, chances the fare is still available would be much higher.

If you know any tool that can do that, let me know! Thanks
