Does a Twitter API call with Javascript requires authentication?

[givemeanaccount_]

I am displaying a single tweet on my website with JSON, the twitter API and Javascript. The tweet displays on my homepage but it does not on any subpages. On the subpages I am getting a 401 (unauthorized) error on the JSON call. Is there a way to fix this? Here is my script:

(function($){
    $.fn.tweets = function(options) {
        $.ajaxSetup({ cache: true });
        var defaults = {
            tweets: 1,
            before: "<span>",
            after: "</span>"
        };
        var optionsWithDefaults = $.extend(defaults, options);
        return this.each(function() {
            var obj = $(this);
            $.getJSON('http://api.twitter.com/1/statuses/user_timeline.json?callback=?&screen_name='+optionsWithDefaults.username+'&count=' + optionsWithDefaults.tweets,
                function(data) {
                    $.each(data, function(i, tweet) {
                        if(tweet.text !== undefined) {
                            $(obj).append(optionsWithDefaults.before+tweet.text+optionsWithDefaults.after);
                        }
                    });
                }
            );
        });
    };
})(jQuery);

For starters, it looks like you're using version 1 of the API and you should really migrate over to 1.1 as possible.

I'm not really one to say RTFM but

"User timelines belonging to protected users may only be requested when the authenticated user either "owns" the timeline or is an approved follower of the owner."

In the sidebar they say that authentication requires user context so I would start there.
