For those who are looking for a solution using the V3 API, you can do the following:

var videoID = 'the_youtube_video_id';
$.getJSON('https://www.googleapis.com/youtube/v3/videos?id=' + videoID 
           + "&key=INSERT_YOUR_API_KEY_HERE&part=COMMA_DELIMITED_VALUE", 
  function (data, status, xhr) {               
    if (data.items.length > 0)
        alert('It is there!')
    else
        alert('Are you sure you about the Id?');

    console.log(status);
    console.log(xhr);
}).error(function (xhr, errorType, exception) {
    var errorMessage = exception || xhr.statusText || xhr.responseText;
    alert(errorMessage);
});
