Not able to get the response in my ember app for google place api

I am sending the request to google place api. I am getting an error

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access.

I am using an api key which I created for testing purpose.I enabled google place web service api.I inserted the the url "http://localhost:4200" while generating the api.I am not sure where I am going wrong.Please suggest how should I make this correct and save the reponse.
