Price datasets
Data for research, not for republishing a price list. Each dataset is a product-level panel: how many independent sellers offered the same item and how far apart their prices were. CC BY 4.0, a checksum with every file, full methodology on the dataset page.
What these files do not contain. No EAN codes and no identifier that would let you join our data with an external catalogue. No shop names and no price attributed to a specific seller. The product identifier is a surrogate — stable within one release and non-reversible. These are statistics we computed, not our partners’ price lists.

What we do not publish yet
We computed these categories and they did not pass the publication thresholds. We list them with the numbers, because staying silent about a failed slice would look like cherry-picking.
