Quantities API

Product size and unit data. Standardized and structured.

The Prodx Quantities API returns standardized, structured quantity data for any product. Each product gets one or more quantity entries with a numeric value, a named unit, and a primary flag indicating which quantity expression is most relevant. Clean, consistent, and ready for downstream calculations.

Why Quantity Data Breaks Down in Grocery

Quantity expressions vary wildly across catalogs, which makes unit pricing, size comparison, and substitution logic unreliable.

Inconsistent Formatting

27 OZ, 27 ounce, and 27oz all represent the same thing differently.

Multiple Quantity Expressions

A product may carry both ounce and count information.

Blocked Downstream

Features Without standardization, unit pricing and equivalence cannot be trusted.

How Prodx Standardizes Product Quantity Data

Prodx returns one or more quantity objects per product, each with a numeric value, unit object, and primary flag, creating clean inputs for downstream calculations and UI.

Pass product IDs to retrieve structured quantity data.
Return multiple quantity expressions when relevant.
Indicate which quantity is primary for comparison or display.
Support unit pricing, comparison, and the Equivalent API.
Create a dependable quantity layer across the catalog.

Measurable Impact

Standardized quantity data is foundational infrastructure. It powers unit pricing accuracy, size comparisons, and quantity-adjusted substitutions across every other Prodx API that needs to understand product size.

More Accurate

Unit pricing

Downstream value features rely on clean quantity data.

Better

Size comparison

Shoppers can compare like for like more easily.

Foundational

Catalog infrastructure

Other APIs gain reliability when quantity data is normalized.
