CORS origin error

[onepercentklub]

Access to XMLHttpRequest at 'http://horoscope-api.herokuapp.com/horoscope/today/Capricorn' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I get the following error when I make a GET request. If you could allow CORS origin that will be great.
Cheers for the Good work.
