// How it works
Read. Rank. Render. Every transaction, end-to-end.
-
Stage 01 · Read
Feature vector assembled
The SDK sends an anonymized feature vector — context, user shape, inventory state — to the Nexos endpoint.
-
Stage 02 · Rank
Every eligible offer scored
Nexos runs the candidate set through the ranker, scoring each on predicted conversion. The bandit balances exploit against explore.
-
Stage 03 · Render
Top creative returned to the page
The winner is returned in 87 ms median. The SDK paints it below the order summary — modal on desktop, embed on mobile.
// The four surfaces
Pick a placement. See what fires.
Each card opens the real interactive surface, populated with one of four sales-example offers. Clickable, dismissable, keyboard-accessible — no live SDK fires.
// Live embed
Drop the embed right into your checkout flow.
