Does anyone have any recommendations for applications or browser plugins that make browsing and visualizing JSON APIs easy.
I'm not completely sure what you're asking.
If you're looking for a JSON viewer to examine complex JSON strings, take a look at JSON Visualizer.
If you're looking for a way to browse an API, consult that API's documentation.
Johns tool is nice. Anoter nice online tool is http://jsonviewer.stack.hu/
This one looks quite good, it's a firefox plugin called JSONView

For completeness there is also this http://www.codeplex.com/JsonViewer I have only tried the stand-alone, and it seems to do the basics ok. However the firefox plugin had less friction for what I was doing.
From the documentation:
The JSON View package is a set of 3 viewers available in the following flavors:
- A standalone viewer - JsonView.exe
- A plugin for Fiddler 2 (http://www.fiddler2.com/) - FiddlerJsonViewer.dll
- A visualizer for Viusal Studio 2005 - JsonVisualizer.dll
Firebug in Firefox does the job when you have a url which returns json (Firebug is a must have for any web developer, if you don't have it installed already, you can get it here): with Firebug open and active navigate to your url in Firefox, in Firebug go to the Net tab, then click + sign next to your url in the grid, there should be a JSON tab available which you can use to explore your object in a tree view.
