Save this to "nicerest", chmod +x-it, and pipe your REST API curl calls through this for nicer output. It will notice HTTP headers (curl's -i option) and skips those before attempting to pretty-print the following JSON.
Note: This is currently using node 0.2. I should update for 0.3 changes (I think process.openStdin changed).

There's also some cool online tools to pretty print JSON. I really like www.jsonprettyprint.net for example.
