Used [fiddler][1] to double-check<sup>*</sup> this. Everything I get back from the API is definitely gzip compressed. For that matter, you can't get a response that isn't compressed; you can only choose between gzip & deflate. Default is gzip. The API always sets the `Content-Encoding` response header, so you might be the victim of your library decompressing the response for you. <sub>*Triple-checked: I ran our test cases without setting `Accept-Encoding` but leaving the gzip decompression code in.</sub> [1]: http://www.fiddler2.com/fiddler2/
