Gist Ads Ad Tag and Display Ad API is one of 3 APIs that [Gist](https://apis.io/providers/gist/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include advertising, ad-tag, ad-serving, contextual-advertising, and monetization. The published artifact set on APIs.io includes API documentation and an API reference.

Advertising delivery surface for Gist Ads. Publishers load the `adtag.js` bundle from tp-at.prorata.ai and call `window.prtag.defineSlot({id, api_key, url, geo}, slotId, sizes, adTypes)` to request contextual ads against a search query; the ad tag then calls the display ad decision service (disp-api.prorata.ai, endpoints `/health`, `/decision`, `/api/v1/chat/`) and the search ad service (tp-srch-api.prorata.ai, which requires Publisher-ID and Publisher-Key headers). The same hosts back the first-party iOS and Android Gist Ads SDKs.
