I have been testing a throttle implementation against meta today and suddenly got shut down with a key violation.

It is possible that I have used enough requests to prompt this but I doubt it.

In any case, is this a proper response for an 'out of requests' error?

Should it not include the 'x-rate-limit' headers?

Or is this a sign of another problem?

The omission of the X-... headers was a bug, and has been resolved.

Be aware, if you provide a key that actually isn't recognized you'll get a 4000 error back not a 4004.
