Notes"We’ve just released a brand new API for BlockChalk. It’s very easy to learn and use: requests are made via HTTP GET and POST, and data is provided in XML, JSON, and RSS formats.
These new interfaces enable developers to do nearly everything that you can do at http://blockchalk.com. It’s now possible to build client applications, mash-ups, and other tools based on BlockChalk geolocation data and services."Unfurl
