What is jsonp

jsonp stands for json with padding.  It's simply wrapping returned json data with a function call.  This enables sites to get around cross-site scripting problems.  You only need to use this if you're trying to get data from chartbeat within a javascript call.

Normally, all the API calls return something like:

{'value': true, 'size': 10}

If you add &jsonp=funcname to any of the calls, you'll get back:

funcname({'value': true, 'size': 10})

This allows you to get the data sent directly to the function 'funcname'

Instead of using an XMLHttpRequest to request the data, you would instead do a simple <javascript> include.
