We build decisioning infrastructure
for consumer platforms.
One API to rank every feed, fill sponsored slots, and explain each decision, the layer between candidate generation and what your users see. Stop building and maintaining a ranking engine in-house.
One endpoint. Ranked decisions and monetized slots in one response.
A versioned REST surface. OpenAPI 3.1 as the source of truth. Every SDK generated from the spec, contract drift across languages is mechanically impossible.
// One endpoint. One ranked decision. $ curl api.gortex.ai/v1/decide \ -H "Authorization: Bearer $GORTEX_KEY" \ -d '{ "recipient": { "id": "u_8120" }, "context": { "surface": "home_feed" }, "items": [ /* 50 candidates */ ] }' { "ranked": [ /* ordered item IDs */ ], "sponsored": [{ "slot": 3, "price": 0.42 }], "decision_id": "d_01HXZ3M…", "trace_id": "t_01HXZ3N…" }
one decision engine, six entry points.
every api below is the same POST /v1/decide call, shaped for one surface. one engine, six ways in, so you adopt the entry point that matches what you rank and monetize.
Questions, answered plainly.
What is decisioning infrastructure?
The layer between candidate generation and the surface a user sees. It decides which items to show, in what order, and where sponsored slots go, then records why. Gortex provides it as a single API, so platforms don't build and maintain that layer in-house.
What does the Gortex API do?
A single call, POST /v1/decide, takes a recipient, a surface, and a candidate set, then returns an organically ranked order and fills monetized sponsored slots in one sub-200ms p99 response.
What is the difference between ranking and retrieval?
Retrieval gathers the candidate set, the items that could be shown. Ranking decides the order they appear in and which slots are monetized. Gortex handles the ranking-and-monetization decision; you bring the candidates.
How does Gortex rank organic results and fill sponsored slots in one call?
Both happen inside one latency budget. Gortex ranks the candidate set by relevance, then resolves sponsored slots against that ranking, so a paid item only takes a slot when the placement fits. Ranked order and sponsored slots come back in the same response.
What platforms is Gortex for?
Consumer platforms that own a ranking surface, social feeds, marketplaces, creator and discovery products, dating apps, and ecommerce. The candidates can be profiles, posts, locations, products or brands.
