API request with ajax

I'm trying to do a get request with ajax to get the product details, but I got CORS error

Access to XMLHttpRequest at 'https://judge.me/api/v1/products/5x11-back-in-black-500-sheets' from origin 'http://localhost:8080' 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 tried from localhost, from a webserver, from shopify and I got the same

using postman works

Do I need something extra in the request?

Thanks

here the jquery example

let url = "https://judge.me/api/v1/products/5x11-back-in-black-500-sheets";                        

    $.ajax({

          url: url,

                      type: 'GET',

                       data: raw,

                       crossDomain: true,

                       dataType: "json"

        }, {

     success: function(data) {

        console.log(data);

  },

     error: function(err) {

        console.log(err);

     }

   });

I'm creating a custom app that only uses HTML, JS and CSS - does the OAuth approach allow for network requests through the Fetch API in Javascript?
