Two calls over your catalog: strategy-based recommendations from input products, and free-text style search. Both return ranked products with a match score where higher is always better.
There is no separate authenticate step — createDesignWithMe() signs in on its first real call below. Your catalog scope comes from the API key; there's no client id to pass.
Settings persist across every example page for this browser tab. Change them, then reload the page to build a new client.
dwm.recommendations.forProducts() — ranked matches for your cart or scene. Threshold is a floor, not a re-rank: it drops results scoring below it and leaves the order alone. Scores often sit close together, so the list only shrinks once the threshold passes the lowest score shown.
dwm.recommendations.search() — describe the style in plain language. Scores here are the same 0–1 match scale as recommendations: higher is better.
One subscription, dwm.on('activity', ...), sees every event this client emits — the same feed powers dwm.activity.log.
