Recommendations API

Show shoppers what to buy next. Based on what actually sells together.

The Prodx Recommendations API returns grouped product suggestions built from real purchase patterns, product relationships, and shopper behavior. Results come organized by relationship type so the experience is both personalized and merchant-friendly.

Why Generic Recommendations Underperform

Most recommendation engines treat grocery like electronics. They miss context, basket logic, and the relationship between items that are actually bought together.

Weak Cross-Sell Logic

'Customers also bought' often produces noise instead of useful next-best products.

No Relationship Context

Retailers need complements, affinities, impulses, and purchases—not one undifferentiated list.

Limited Merchandising Control

If teams cannot weight recommendation types by page or goal, recommendations stay generic.

How Prodx Structures
What to Recommend Next

Prodx combines the output of multiple underlying engines—Predictions, Complements, Impulses, and Affinities—to deliver grouped, high-impact suggestions that can be tuned by placement and intent.

Returns grouped recommendation sets such as Complements, Affinities, and category-specific picks.
Uses shopper preferences, category context, purchase history, and product attributes together.
Lets retailers tune the recommendation mix to match business goals or page placement.
Supports product page carousels, cart suggestions, substitution flows, and discovery surfaces.
Surfaces recommendations from grounded data instead of black-box collaborative filtering.
