Ad2iction Prebid Bid Endpoint is published by [TNL Mediagene](https://apis.io/providers/tnlmedia/) on the [APIs.io](https://apis.io/) network. Tagged areas include AdTech, Advertising, Header Bidding, Prebid, and Programmatic. The published artifact set on APIs.io includes an API reference and rate-limit docs.

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.
