In-house mediation is not publicly available
In-house bidding with Audience Network is currently in Closed Beta and is not publicly available. We'll provide further updates if this changes.
In the meantime, you can access Audience Network Bidding through one of the mediation platforms we partner with.
In-house mediation is a model that allows you to build your own mediation stack with multiple bidders (including Audience Network) and run the auction yourself. This provides high customizability and control and is generally for publishers with well-resourced developer teams, or for mediation partners.
