SoundCloud created_at[from] query resolving in a 503 error - api

Question

Using the JavaScript SDK, I am trying to search for all tracks in a given genre from a given date going forward (using the 'created_at[from]' /tracks filter).
My JavaScript for this is:
SC.get('/tracks', { genres: 'metal', created_at: {from: '2014-02-26 00:00:01'} }, function(tracks) {
console.log(tracks);
});
The request URL resolves as:
http://api.soundcloud.com/tracks?genres=metal&created_at[from]=2014-02-26%2000%3A00%3A01&client_id=MY_ID
and I get a 503. (I omitted posting my client_id here intentionally)
What am I doing wrong here?

Answer 1

Looks like they changed the filter or its a bug or they are working on it:
When i call:
http://api.soundcloud.com/tracks?limit=1&genres=metal&client_id=b45b1aa10f1ac2941910a7f0d10f8e28&created_at=2010-10-10
I am getting:
invalid filter.created_at=2010-10-10;
valid values are: last_year, last_two_weeks, last_week, last_day, last_hour
Then, when i call for last hour:
http://api.soundcloud.com/tracks?limit=1&genres=metal&client_id=b45b1aa10f1ac2941910a7f0d10f8e28&created_at=last_hour
I am getting a: 503 - Service Unavailable
When i change it to last_year, it works as expected,
and i get following xml (or json):
<tracks next-href="http://api.soundcloud.com/tracks?client_id=b45b1aa10f1ac2941910a7f0d10f8e28&created_at=last_year&genres=metal&limit=1&offset=1" type="array">

EDIT:
I'd say you are right and SC Team should give an answer on that.
