description: >-
  TNL Mediagene's only publicly published, machine-readable client-side integration
  surface: the Ad2iction Bidder Adapter shipped inside Prebid.js. Ad2iction is TNL
  Mediagene's ad-technology subsidiary (acquired by TNL Media Group in 2020;
  described as "its subsidiary Ad2iction" in TNL Mediagene's own December 2025
  press release). The adapter is a first-party-maintained open-source JavaScript
  module — maintainer contact prebid@ad2iction.com — that a publisher drops into
  their Prebid.js build to send header-bidding requests to Ad2iction's demand.
  This is a client-side embeddable component, not a server SDK; there is no
  Ad2iction client library on any package registry.
ownership_note: >-
  The bid endpoint is on ads.ad2iction.com rather than tnlmediagene.com because the
  ad-technology business runs under the acquired Ad2iction brand and its own domain.
  The adapter names prebid@ad2iction.com as maintainer and points integrators at
  https://www.ad2iction.com for onboarding, and TNL Mediagene's corporate site links
  ad2iction.com among its own properties.

            The endpoint returns a bare JSON array of Prebid bid response objects.
            The adapter returns [] for any non-array body. No error envelope, status
            field, or problem-details structure is defined by the adapter.

        onboarding: >-
          Contact-gated. The adapter README states "requires setup before beginning.
          Please contact us on https://www.ad2iction.com" — the placement id is
          issued by Ad2iction, there is no self-service signup.

    Certificate transparency for ad2iction.com exposes tnlmgtag.ad2iction.com and
    tnlmgtag-test.ad2iction.com, consistent with a TNL Mediagene first-party tag
    delivered from the Ad2iction infrastructure. No public documentation for the tag
    was found, so no component is recorded for it.
