Penny API — Register Your Interest
Penny is Rewe Group's discount supermarket chain, one of Germany's most visited discount retailers. A Pepesto integration would give developers access to Penny's product catalog from penny.de — pricing in EUR, weekly offers,, returned as clean JSON.
What Would the Penny API Return?
If launched, the Penny integration would use the same unified schema as all 25+ live Pepesto chains — the same JSON fields, same endpoint, same API key.
What Can You Build?
The Penny API gives your product a live data layer on top of one of Germany's leading grocery retailers.
Give your AI agent the ability to search Penny's catalog, compare products by price or nutrition, and place grocery orders — all programmatically via REST.
Compare Penny prices against other Germany retailers in real time. Flag promotions, track price history, and surface the best deal per product.
Let users build a weekly shopping list and see the exact Penny cost — including any active promotional prices — before they shop.
Match recipe ingredients to real Penny products and show the true cost of cooking from a given menu. Drive grocery orders directly from your meal planner.
Bridge meal planning and shopping: match recipe ingredients to real Penny catalog products and power dietary-aware grocery lists with live pricing.
Monitor Penny's product range, pricing strategy, and promotional cadence at scale. Analyse SKU composition, spot price movements, and benchmark against competitors.

Frequently Asked Questions about the Penny API
Penny does not offer a public developer API. Pepesto is evaluating a Penny integration that would normalise Penny's product catalog from penny.de into consistent JSON.
Yes. Penny is owned by the Rewe Group, the same parent company as Rewe (shop.rewe.de). However, Penny and Rewe are completely separate retail brands with different product catalogs, pricing, and store formats. Pepesto would treat them as separate integrations.
If launched, the Pepesto Penny API would return the unified schema used across all 25+ live chains - product name in German, price in EUR, promotional price, unit price.
Yes. Penny's weekly promotional offers are a key part of the catalog experience and would be captured alongside standard prices in every daily refresh.
No confirmed release date. Register your interest above — this signals demand and directly influences our prioritisation.
Yes. Penny operates in Austria, Czech Republic, Hungary, Romania, and Italy in addition to Germany. A Pepesto integration would be scoped to penny.de (Germany). Other Penny markets could be considered as separate integrations.
Everything visible and related to food, cooking, and recipes in the Penny mobile web application, returned as clean JSON via a single REST call. The indexed product list typically contains 1,000–2,000 SKUs, focused on the most common ingredients used for cooking.
