# Exchange Specification for DSPs

Triton Digital's audio ad exchange allows buyers to purchase inventory from many audio publishers (see the list, [here](https://www.tritondigital.com/resources/a2x/publisher-listing)). Inventory is available in Open Auction or through a PMP (private deal between publisher and buyer). In either case, the inventory is not guaranteed.

The Triton Digital ad exchange uses the OpenRTB protocol version 2.5, which introduces support for audio. For details, see [OpenRTB Implementation](/v1/docs/openrtb-implementation).

This document is a general guide for demand-side platform (DSP) operators using the Triton Digital ad exchange. It includes information on the [validation tests](/v1/docs/dsp-validation-tests) that are conducted when the exchange is provisioned for a DSP.

For updates, see the [Change Log](/user/docs/change-log-exchange-spec).
