Ajax request to a RESTful API giving CORS Policy error

I'm trying to make a simple call using this RESTful API for charity data. Here is my JQuery code:

$.ajax({
      url:  'https://projects.propublica.org/nonprofits/api/v2/search.json?q=america&c_code%5Bid%5D=3',
      dataType: "json",
      method: "GET",
      success: function( data ) {
        console.log("success");
      },
      error: function() { 
        console.log('failure'); 
      }
    })

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

When the code is triggered, it returns the following error:

Access to XMLHttpRequest at 'https://projects.propublica.org/nonprofits/api/v2/search.json?q=american&c_code%5Bid%5D=3' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Am I doing something wrong, or is there an issue with the API?
