Open data
Some prices in NomNom are computed from Open Prices, a database built by Open Food Facts contributors. The price rows we derive from it are open data: download, reuse and share them under the ODbL.
| Country | Rows in the app | Observation window | File |
|---|---|---|---|
| Germany | 39 | 2025-10-20/2026-10-20 | de.json |
| Denmark | 0 | - | dk.json |
| France | 67 | 2025-10-20/2026-10-20 | fr.json |
| Sweden | 33 | 2025-10-20/2026-10-20 | se.json |
| United States | 41 | 2026-09-09 | us.json |
The same list as JSON: index.json.
Every file is served with CORS, so it can be fetched from any site. When a monthly
price release is live for a country, its file also lists that release's rows under
release, read from the live release itself.
What a file contains
- Each row the price book takes from Open Prices: the ingredient, the method, the Open Prices categories and filters, the number of observations, the median, the correction factor and the resulting price per recipe unit.
- The observation window and the price book edition it belongs to, and for every
Open Prices ingredient the recipe unit and filters (
anchors). - No product barcodes, shops, locations or contributors: only the medians and what is needed to reproduce them from Open Prices.
Our other price sources (national statistics offices, Eurostat, our own shelf prices) are independent data and are not part of this database.

Magyarul
A NomNom néhány árát az Open Prices közösségi adatbázisából számoljuk. Az ebből képzett ársorok nyílt adatok: az ODbL feltételeivel szabadon letölthetők és újrahasznosíthatók. A fájlokban nincs vonalkód, bolt, hely vagy beküldő, csak a mediánok és ami a megismétlésükhöz kell.
