WURFL Prebid.js is a real-time device detection provider module designed to integrate seamlessly with Prebid.js, a leading header bidding solution for digital advertising. The module enriches the OpenRTB 2.0 device data in bid requests with WURFL’s high-accuracy device capabilities, such as device type, model, and form factor. This enrichment enables publishers and demand partners to achieve more precise audience targeting and improved ad performance. The module operates by dynamically loading JavaScript from ScientiaMobile’s WURFL Cloud, populating device information in the bid request so that all bidder adapters can access it. WURFL Prebid.js is compatible with modern browser privacy features, including User-Agent Client Hints, and can automatically request high-entropy client hint values when needed. The solution is designed for publishers and ad tech platforms seeking to maximize ad revenue and user experience through advanced device intelligence, without relying on external device detection APIs during the bidding process.
