How this service works
Distribution of latest included product/store observations, with regular and promotional prices separate. Example: category en:pastas, country DE. Cheapest means cheapest included observations, not the whole market.
Output
A distribution of the latest included price observations for the requested category or EAN in the specified country, with regular and promotional prices reported separately. Prices represent the cheapest observations in the dataset (not necessarily the whole market), expressed per unit of mass or volume (kg or litre).
Example use cases

Budget grocery comparison for Austrian shoppers

Price tracking for a specific product EAN

Endpoint
POSThttps://grundpreis.halowerk.com/v1/category-unit-prices?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need per-unit (kg/litre) price benchmarks for food categories or specific EAN products in Germany or Austria, especially when you want to distinguish between regular shelf prices and promotional/sale prices. Prefer this over general product search APIs when the goal is price comparison or unit-price analysis grounded in Open Food Facts taxonomy.
Side effects
- Invalid or unrecognized Open Food Facts category tag returns no results
- EAN not found in the dataset returns empty or error response
- Country code outside DE/AT is rejected by enum validation
- Category string too short (under 3 chars) or too long (over 80 chars) fails validation
- No observations available for a valid category/country combination returns empty data
