webread not working for JSON

I can read from url's and api's just fine as long as the return format is not JSON. Some examples from matlab help that don't work for me
>> api = 'http://climatedataapi.worldbank.org/climateweb/rest/v1/';
url = [api 'country/cru/tas/year/USA'];
S = webread(url)
S =
Empty matrix: 0-by-1
But this works just fine:
fullURL = ['http://www.mathworks.com/matlabcentral/fileexchange' ...
'?term=urlread'];
str = urlread(fullURL);
>> whos str
Name Size Bytes Class Attributes
str 1x82552 165104 char
Has anyone else had this issue? It use to work just fine for me a few months ago. I wonder if it is some internet setting issue.

Leah - looking at the example at webread, have you tried to include the options parameter? What happens when you try
options = weboptions('ContentType','text');
data = webread(url,options);
where url is what you have described in your question?
And, what happens if you navigate (in any web browser) to the URL http://climatedataapi.worldbank.org/climateweb/rest/v1/country/cru/tas/year/USA? Do you see the alternating year data from 1901 to 2011?
