Filters API

Faceted filtering that actually works. Because the data is right.

The Prodx Filters API returns accurate, enriched filter facets for any set of products. Every product is mapped to its correct filter options across Category, Diet & Lifestyle, Brand, Type, Section, and Form. Filters are generated from Prodx’s enriched data, not raw retailer metadata.

Why Static Filtering Breaks Trust

Most grocery filter menus are not generated from the actual products being shown. The result is clutter, dead ends, and low confidence.

Irrelevant Options

The same filter menu appears whether the shopper is browsing bread or baby formula.

Missing Relevant Facets

If the right filters are absent, the experience feels incomplete.

Low Trust in Results

Bad filters create zero-result combinations and wasted clicks.

How Prodx Generates Context-Aware Filters

Prodx uses structured product data to return dynamic filters based on the actual products in view, with mapped product-to-filter relationships across category, diet, brand, type, section, and form.

Pass product IDs from a search or category result set.
Return available filter facets with valid options tied to the products in view.
Provide a product-options map showing exactly which filters apply to each product.
Use structured product categories, quality types, and product-level quality tagging.
Support consistent shopper refinement across search and category browsing.

Measurable Impact

Accurate filters mean shoppers can trust the results they see. Retailers using Prodx Filters see fewer zero-result filter combinations and higher filter usage rates, which directly correlates with higher conversion.
