JQuery getJSON callback not executing

Question

It's been a while since I've worked front-end, and I seem to have forgotten it all. I cannot get this call to the bing API to work, or even do anything . . .

 $( document ).ready( function() {
     $.getJSON( 'http://api.search.live.net/json.aspx?Appid=**my app id**6&query=sushi&sources=web', function( data ) {
         alert ( 'BAM!' );
     } );
 } );

I've looked at other SO questions but haven't found anything that works. The error log shows nothing. The ready function is executing, I tested that, but the getJSON callback never executes.

Is it possible the bing api is returning a malformed json?
