Economical API

Show shoppers the better deal. Automatically.

The Prodx Economical API returns value-ranked alternatives for any product, each with per-unit pricing, total savings, and quantity context. Shoppers instantly see which option gives them more for their money. No math required. Retailers can also configure the API to surface private label options first — a simple lever for driving own-brand adoption without sacrificing the value experience.

Why Value Comparison Is Hard Online

Price-conscious shoppers want the best value, but most grocery sites only show shelf price and leave the comparison math to the customer.

No Unit Context

Shelf price alone does not tell the full value story.

Weak Trade-Up Experience

Retailers miss the chance to guide shoppers toward better pack economics.

Eroded Share of Wallet

In inflationary conditions, value clarity matters more than ever.

How Prodx Makes Value Obvious

Prodx ranks alternatives by value and shows price per unit, savings per unit, total savings, and quantity context so retailers can support trust, trade-up, and private-label strategies.

Pass a product ID to receive up to 100 value-ranked alternatives.
Return price, quantity, price-per-unit, savings-per-unit, and total savings.
Show when switching size, brand, or pack count delivers better value.
Optionally bias outputs toward private label or strategic assortments.
Power 'Better Value' badges, comparison modules, and upsell prompts.
