Reading an http file in csv format

I want to read this csv file “http://api.pluralsight.com/api-v0.9/courses” into a snap
When I used mapper and file reader, I obtained this error message:
Failure: Unable to read from http://api.pluralsight.com/api-v0.9/courses, Reason: The file can not be accessed: http://api.pluralsight.com/api-v0.9/courses, Resolution: Verify that access permissions are granted on the file: http://api.pluralsight.com/api-v0.9/courses
