I'm using meteor application and Untill now I'm making api calls like below

     var urlString = "http://api.stackexchange.com/2.2/users/"+surl;
     HTTP.call("GET", urlString,{params:{site:"stackoverflow"}},function(error,result)
            {
                 console.log(result.data);

I have a Meteor application and I'm making API calls like:

var urlString = "http://api.stackexchange.com/2.2/users/"+surl;
HTTP.call ("GET", urlString, {params:{site:"stackoverflow"}},  
    function (error,result) {
        console.log (result.data);
    } 
);

How do I request, using the API key, so I can get 10,000 calls per day?
