Sharethrough is an omnichannel programmatic advertising exchange (SSP) for native, display, video and CTV inventory, and one of the largest independent ad marketplaces. Publishers monetise through the Prebid.js header-bidding adapter and server-to-server OpenRTB; demand partners buy through the exchange. Two API surfaces exist: a bearer-token Publisher Reporting API at publisher-api.sharethrough.com/v2 whose public reference is now behind a support-site sign-in, and the unauthenticated OpenRTB bid endpoint at btlr.sharethrough.com/universal/v1 used by the Prebid adapter. The company's richest machine-readable artifact is its IAB sellers.json (5,189 sellers). Sharethrough merged with Equativ in 2024 and has operated under the Equativ brand since June 2025; the Sharethrough exchange and its endpoints continue to run.
