For those of us who don't know (and are too lazy to google CORS :-))
could you provide an example of how to replace uses of the JSON API?
For example, a script I currently use has:

url = 'https://pypi.python.org/pypi/' + args.name
req = requests.get(url + "/json")
data = req.json()
url = data['info'].get('home_page', url)

Thanks,
Paul
