The OpenXBuild™ Software Suite
Real-Time Bidstream API
Target high-value consumers before the auction happens. Deploy your data and decisioning within the OpenX Supply Cloud for real-time targeting, smarter bidding, and improved performance.
Identity Resolution API
Combine audience data with the industry’s largest independent supply-side Identity Graph in the OpenX Cloud to resolve identity and expand reach across channels.
Auction Insights API
Access privacy-safe OpenX log-level data – such as people exposures, supply dynamics, and auction results – to power better insights, decisioning models, and outcomes.
“With OpenXBuild, we can apply our audience enrichment and bidding algorithms directly inside the exchange. By evaluating impressions closer to supply and bidding more selectively, advertisers have seen a 70% reduction in cost-per-conversion on OpenX traffic compared to unshaped SSP inventory.”
