h2. Overview

Through is a small geolocation web API. You can use it to:

• Look up the location of an IP address
• Find out the time zone for a location
• Get responses in JSON
• Centralise your geographical data so each of your apps don’t need to store it

I didn’t want to reproduce the same functionality across my web apps, so I thought an API would be a good solution.
