$.getJSON parsererror trying to call API

问题

I'm trying to use the Clipped API (http://clipped.me/api.html) that returns JSON but am running into some trouble. I'm using getJSON, and in Chrome's JS console I get these error messages:

Resource interpreted as Script but transferred with MIME type text/html: "http://clipped.me/algorithm/clippedapi.php?url=callback=jQuery1910859611126…emo-day-2013-still-looking-for-the-next-airbnb-or-dropbox/&_=1364420105379".

Uncaught SyntaxError: Unexpected identifier

Request Failed: parsererror, Error: jQuery19108596111265942454_1364420105378 was not called

And here's my JS:

var clippedAPI = "http://clipped.me/algorithm/clippedapi.php?url=[URL]callback=?";
    $.getJSON(clippedAPI, "http://pandodaily.com/2013/03/26/y-combinator-demo-day-2013-still-looking-for-the-next-airbnb-or-dropbox/" ).done(function(json) {
            console.log("JSON Data: " + json.title );
    }).fail(function(jqxhr, textStatus, error){
            var err = textStatus + ', ' + error;
            console.log("Request Failed: " + err);
    });

This is my first time trying to make something with an API or JSON at all, so I'm really not sure what to do here. I've tried Googling around but can't find anything. The data that I'm actually sending is getting cut off by this jQuery notice that appears when I add callback=?

Your parameter will not simply "guess" what the [URL] param is. Try this:

var clippedAPI = "http://clipped.me/algorithm/clippedapi.php";
$.ajax({
url: clippedAPI,
type: "GET",
dataType: "JSONP",
data: {
url: "http://pandodaily.com/2013/03/26/y-combinator-demo-day-2013-still-looking-for- the-next-airbnb-or-dropbox/"}
}).done(function(json) {
        console.log("JSON Data: " + json.title );
}).fail(function(jqxhr, textStatus, error){
        var err = textStatus + ', ' + error;
        console.log("Request Failed: " + err);
});

Even this fails, however, as your API endpoint does not seem to understand/support JSONP and does not provide a Access-Control-Allow-Origin header. You therefore have two choices:

You can reverse-proxy the API locally to get around the cross-domain issue and go through standard JSON
You can...ehm... get a better API? Lodge a ticket with the devs to get it sorted.
