Supply

Inventory

First-party properties run in this app. The tag is the human contract. POST /api/ads/run is the agent contract — same auction, the page (or the agent’s payload) is the task. Paste the tag on multinicheai.com or any other page. Each pageview auctions against the live book. A run bills when they execute the SKU on that page. Clicks still 302 to the destination.

Agent protocol

ChatGPT and Google keep ads inside their apps. An agent on the open web auctions here, then POSTs its own task. The SKU runs on that task. They keep the spec.

GET https://your-exchange.example/api/ads/offer?q=deep+work+prompts&site=agent.local
POST https://your-exchange.example/api/ads/run
{ "e": "<eventId>", "title": "my job", "excerpt": "the work to run the spec on" }
GET https://your-exchange.example/llms.txt

Response is a SpecOffer with acceptsTask. POST the page (or any job) to runUrl. A run bills once. Humans tap Run it on this page. They can keep the spec.

Open-web tag

Same auction as Findr and the Digest. After you publish, this origin is the ad server.

data-site is the host. data-format is display, social, or search. data-tags steers quality. Add as many data-mn-ad nodes as you have slots; one script.
