Acquiring a JSON from a webpage

Hi all,
I'd need to find a way to acquire a JSON file from a web portal. I can do it manually just by going to the site and save in JSON (see screenshot). However, I'd like to be able to do it directly from Matlab, but webread just returns the HTML code, not the data I'm looking for. I tried using the options:
options = weboptions('ContentType','json');
But it failed. Any idea is welcome

Thanks,

Try this:
headers = {'Content-Type' 'application/json'; 'Accept' 'application/json'};
options = weboptions('HeaderFields',headers);
webread('http://ip.jsontest.com', options)

I see. It seems like you just got back the html for the login page. In general, there shall be an API key for authentication. Or try to put your username/password into the headers as well.
