How to get in

A programmatic exchange — inventory trades in real-time auctions between machines, at prices neither side publishes.

As a publisher

Exchanges rarely take direct signups from individual sites. The path in is an SSP relationship, a header-bidding wrapper (Prebid) or a monetization partner that already holds a seat — or a publisher network that resells into it.

As an advertiser

You buy its inventory through any DSP with the integration — The Trade Desk, DV360, StackAdapt and the rest — not on the exchange itself.

Start-here links are read from the network's own site; where none shows, the system offers no public door and is reached through partners.
