I am making a website that needs to get the listings from the steam community market.  I know how to get the JSON, but I'm getting a console error: Uncaught SecurityError: Failed to set the 'domain' property on 'Document': 'https://steamcommunity.com/' is not a suffix of ''.  It looks like I set the wrong domain.  Does anyone know the correct domain I need to use?
My JavaScript code:
    <script>
        document.domain = "https://steamcommunity.com/";
        $(document).ready(function() {
            $.getJSON("http://steamcommunity.com/market/priceoverview/?country=US¤cy=1&appid=730&market_hash_name=P90%20%7C%20Asiimov%20%28Factory%20New%29", function(results) {
                $("#price").text(results.lowest_price);
            });
        });
    </script>
