What platforms are supported for use with the StackExchange API?
All responses from the API will be compressed with GZIP. The
Content-Encoding header will be set appropriately, but be aware that some proxies will strip this header (along with the corresponding
Accept-Encoding header) so its presence should not be relied upon.
All returned values will be JSON encoded. The API does support the
jsonp parameter for cross-domain requests.
Why is GZIP support required?
Not GZIP'ing (more generally, compressing) wastes bandwidth, and reduces performance.
