description: 'Audigent is a data activation, curation and identity platform for digital advertising, acquired by Experian
  in December 2024 and now operated as part of Experian Marketing Services. Its products include the Hadron ID cookieless
  identifier, the SmartPMP, ContextualPMP and CognitivePMP private-marketplace suites, a first-party data platform for publishers
  and advertisers, and the 1st Unit rich-media format. Audigent''s public technical surface is not a documented REST developer
  program: it is a set of live ad-tech identity, segment and analytics endpoints on the ad.gt and hadronid.net domains, reached
  through first-party open-source Prebid.js modules (hadronIdSystem, hadronRtdProvider, hadronAnalyticsAdapter) that Audigent
  authors and maintains upstream in the Prebid.js project. Audigent is IAB Europe TCF Global Vendor List vendor 561 and publishes
  a machine-readable device-storage disclosure.'

- name: Hadron ID API
  description: Public, anonymous identity-resolution endpoint that returns Audigent's cookieless Hadron ID (plus hadronIdv2
    and the legacy haloId) for the calling browser. Called by the Prebid.js hadronIdSystem user-id submodule. Accepts a partner_id
    identifier and consent signals (gdpr, gdprString, us_privacy, gpp, gpp_sid) as query parameters and responds with JSON.
    No OpenAPI is published; the request contract is legible in the open-source Prebid.js module source.
