OpenX’s product roles diverge
OpenX’s product pages describe these roles, according to sources checked on 2026-10-31.
- OpenXSelect: curation, supply-side targeting, and deal creation.
- OpenXBuild: software suite for building advertising solutions.
- OpenXControl: publisher yield and monetization, connecting publishers to premium demand.
- OpenXExchange: marketplace for inventory and automated ad buying.
Exchange access starts with ad space
OpenX describes its exchange as connecting companies that offer advertising space on websites and mobile applications.
The legal pages identify OpenX as OpenX Technologies, Inc. and its affiliates and subsidiaries for the Website Terms. Separately, the Supply Policy defines a site as a website or a mobile or CTV app. That definition sets a policy term; it does not establish that a site carries affiliate offers or participates in a CPA arrangement.
Compare roles before network names
Compare providers by whether they serve publishers or advertisers, how tracking is handled, which payout terms apply, and what traffic is eligible. In general, matching those operating criteria to the work you need to do is more useful than comparing category labels alone.
Choose curation or infrastructure
Choose OpenXSelect if the task is curation, supply-side targeting, or deal creation; OpenX describes it as serving brands, agencies, and data partners. The provider also describes direct publisher connections, curated inventory, quality scores, and supply authentication and protection. Its curated deals are described as offering controls for quality, brand suitability, and contextual relevance, with transactions across DSPs.
The provider describes OpenXBuild as a software suite for building advertising solutions using cloud-native infrastructure. The provider says OpenXBuild provides real-time bidding, identity, and measurement solutions for omnichannel supply. The provider says users can deploy containerized solutions on that infrastructure and activate them on a preferred DSP.
Commercial terms need a separate check
The Ad Exchange Terms apply to companies headquartered in North America, Central America, South America, or the Caribbean, according to OpenX’s legal page. This geographic scope belongs to those terms and should not be treated as a statement about every product or website visitor.
Website use has separate conditions: OpenX says using the Website signifies acceptance of its Terms, and users who disagree are told not to use it. The provider may revise those Terms by posting new versions, with continued Website use constituting agreement to the revisions. These are website-use provisions, not commercial product pricing.
OpenX’s Website Terms describe the Website as provided “as is” and “as available,” and disclaim warranties to the fullest extent permitted by law. They also disclaim liability for specified categories of damages arising from or relating to Website use. Read these provisions separately from any commercial agreement governing a product.
Bid requests change before auction
The provider says the Real-Time Bidstream API deploys data and decisioning in a secure container within OpenX cloud infrastructure. The provider says the API can shape bid requests before auction for audience targeting and bidding. The provider says OpenXBuild can enrich and shape bid requests before they reach the DSP.
The provider says the Identity Resolution API matches audience data across identity frameworks using an independent supply-side ID graph. The provider says its Auction Insights API provides privacy-forward log-level data, including exposures, supply dynamics, and auction results.
Product scope spans supply and tools
OpenX’s own descriptions show a product set spanning advertising infrastructure, curation, publisher monetization, and exchange buying.
- The product pages separate curation and deal creation from publisher yield and monetization, giving buyers distinct functions to assess rather than one undifferentiated offering.
- OpenX says its platform provides direct media access, privacy-forward targeting, and advertising infrastructure. These are provider-described capabilities, not independently verified performance findings.
- OpenX describes customizable solutions and control for partners, alongside a strategy prioritizing direct partnerships and interoperability.
- The company says it offers proprietary AI-powered curation tools intended to improve advertiser performance; that stated aim does not establish measured results.
The supplied material contains no competitor entries, so these points describe OpenX’s stated scope rather than advantages over alternatives.
Website terms limit submission control
OpenX’s Website Terms restrict certain automated access and give the provider discretion over user submissions.
- The Website Terms prohibit excessive automated request rates and scraping without express permission; this is a website-use condition, not a stated product-plan limit.
- Submissions are treated as non-confidential and non-proprietary, and the provider says users grant it a broad license without an expectation of compensation or confidentiality.
- The submission license remains in effect after a user deletes or removes the submission.
- OpenX says it may edit, refuse, or remove submissions at its discretion; a Terms violation automatically ends permission to use the Website and its content without prior notice.
These clauses concern Website use, not commercial product terms. Missing commercial details are listed under What we could not confirm.
Adtech teams match the stated scope
OpenXBuild’s stated scope addresses teams building advertising technology around bidding, identity, measurement, and auction data. The provider says partners can use audience, publisher, and supply-side auction data when building adtech.
OpenX describes containerization for deploying custom models, data logic, or decisioning code in a private cloud-native environment. The company also says its security systems are audited under the SOC 2 framework and that SOC 3 Type 2 reports are available; its privacy infrastructure is described as regularly assessed by an independent auditor. These statements are provider claims, not independent verification.

- Payout currencies, methods, minimums, schedule, and holds
- Registration and moderation procedures
- Permitted traffic sources, verticals, and GEO eligibility
- Tracking, postback, API access terms, and support arrangements
Questions the product pages raise
Where is the OpenX identity graph available?
OpenX says its identity graph is available only in the U.S. That geographic condition applies to this identity graph; it does not establish the availability of every OpenX product or service in other markets.
What audience scale does OpenX cite for connected TV?
The OpenXSelect page claims audience targeting that includes more than 245 million connected TV users in the U.S. This is the provider’s stated audience figure, not an independently verified count or a claim about CPA traffic.
How many data partners does OpenX say it integrates?
OpenX says it has more than 80 directly integrated data partners, according to its OpenXSelect page. The statement describes integrations cited by the provider; it does not specify commercial terms or the role of each partner.
What request volume does the OpenXBuild page report?
The OpenXBuild page reports an average of over 500 billion daily ad requests, according to the provider. This is a reported platform-volume figure, not a measure of campaign delivery, conversion tracking, or CPA offer activity.
What does OpenX say its ID Graph can address?
OpenXBuild’s page states that its ID Graph can address over 275 million individual people in the U.S. The figure is presented by the provider and should be read as a statement about the graph’s stated reach, not as a guaranteed match rate.
Which policy covers advertising partners?
OpenX’s legal page says the Demand Policy requires advertising partners to meet certain minimum standards. Separately, its Website Privacy Policy describes personal-data processing and applies only to visitors to the OpenX website. These documents address different scopes.
Decide by workflow, not label
Fits if… the work involves evaluating programmatic supply, curation, publisher monetization, or advertising infrastructure described in OpenX’s product pages.
Probably not if… the decision requires evidence of a CPA offer-and-commission workflow; the supplied material instead describes an SSP and advertising exchange.
Main risk… treating product descriptions as a substitute for commercial terms. Compare the intended operating role with the contract and publisher conditions before proceeding.
