Problem with json

Question

Why am I unable to recover this json from the web service of the api I am using.

var url = "https://api.roomorama.com/v1.0/rooms.json?access_token=RS97GGOxoeuo66dXwF4UcHhjmgKjUnAjDiBVDAVTo";  
function preenche(){
     $.getJSON(url, function(dados){
        //log para mostrar quando o getJson funcionou
        $('.greeting-thumbnail').append(" 1234");
     });
}
