TNL Mediagene

TNL Mediagene is a next-generation digital and technology media group serving millennial and Gen Z audiences across Asia. Formed from the 2023 merger of Taiwan's The News Lens and Japan's Mediagene, the group operates more than twenty media brands spanning news, business, technology, lifestyle, and sports — including The News Lens, INSIDE, Cool3c, Gizmodo Japan, Business Insider Japan, Lifehacker Japan, Roomie, and licensed titles such as Digiday Japan and Glossy Japan. Beyond publishing, the company runs advertising and marketing technology (the Ad2iction DSP), an AI-driven customer data and audience analytics platform, e-commerce properties, and market-research services. It is a portfolio company of 500 Global and is listed on Nasdaq as TNMG. The group publishes no developer portal, no OpenAPI, and no SDK. Its one public, machine-readable integration surface is the Ad2iction header-bidding adapter shipped inside Prebid.js — a first-party-maintained open-source module that posts bid requests to https://ads.ad2iction.com/html/prebid/, documented on the Prebid.org bidder registry rather than on a TNL Mediagene developer site.

TNL Mediagene publishes 1 API on the APIs.io network. Tagged areas include Company, Media, Publishing, Advertising, and AdTech.

TNL Mediagene’s developer surface includes API reference, engineering blog, and 14 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/tnlmedia: open an issue to ask a question, or submit a pull request to add artifacts.

- name: Ad2iction Prebid Bid Endpoint
  description: 'The header-bidding demand endpoint operated by Ad2iction, TNL Mediagene''s ad-technology subsidiary (acquired
    by TNL Media Group in 2020). Publishers reach it through the `ad2iction` bidder adapter shipped in Prebid.js: the adapter
    POSTs an application/json body carrying `ids` (a JSON array of {bannerId, bidId} pairs, one per ad unit), the OpenRTB
    2.x `ortb2` first-party data object, Prebid `refererInfo`, an adapter version constant `v` (currently 3), a `udid` read
    from the first-party ad2udid cookie, and a cache-busting timestamp. The response is a bare JSON array of Prebid bid responses.
    Banner is the only supported media type; there is no Prebid Server adapter. The call is unauthenticated but placement-gated
    — the required `id` bid parameter is an Ad2iction-issued placement identifier obtained by contacting the company, and
    there is no self-service signup.'
