### zstd bid compression

CloudX now supports zstd compression for OpenRTB traffic with demand partners, on both bid requests and bid responses.

* Bid requests can be sent with `Content-Encoding: zstd`; gzip remains supported.
* When CloudX advertises `Accept-Encoding: gzip, zstd`, partners may respond with gzip or zstd.
* Contact CloudX to enable zstd for your bidder endpoint.
