On a remote server, there is an HTML page with javascript. The user visits this page, makes some settings, and runs an API query.

How can I ensure that all API queries are routed independently from the user's location through a specific IP address, which is my proxy gateway? How is it possible with javascript?

This is the whole function that runs API query:

function Query(keyword)
{
    var qk = keyword;
    var queryresult = '';
    queryflag = true;


    $.ajax({
        url: window.location.protocol + "//apiv3.example.com/lookup",
        jsonp: "jsonp",
        dataType: "jsonp",
        data: {
        q: qk,
        client: "chrome",
        hl: document.querySelector("select").value
        },

        success: function(res) {
            var rL = res[1];

            var i = 0;
            for(i = 0; i < rL.length; i++)
            {
                var currents = CleanVal(rL[i]);
                if(hashMapResults[currents] != 1)
                {
                    hashMapResults[currents] = 1;
                    SaveLatest(CleanVal(rL[i]));

                    ktq[ktq.length] = currents;

                    var j = 0;
                    for(j = 0; j < 26; j++)
                    {
                        var chr = String.fromCharCode(97 + j);
                        var currentx = currents + ' ' + chr;
                        ktq[ktq.length] = currentx;
                        hashMapResults[currentx] = 1;
                    }
                }
            }
            FilterAndDisplay();
            var textarea = document.getElementById("input");
            textarea.scrollTop = textarea.scrollHeight;
            queryflag = false;
        }
    });
}
