Cool project, but have mixed feelings about publishing ever easier ways to access this API. They've locked down the API a while ago for a reason.

Also there already exists this reverse engineered project: https://github.com/ByteSizedMarius/rewerse-engineering/

I do have a suggestion for your app though: Have it compare your basket of goods across different markets in your region to show you the cheapest option. I'm pretty sure this possibility is actually one of the reasons they locked down the API.

I've used Data from REWE in the past and made a comparison between a couple of cities in Germany (I believe it was Frankfurt, cologne, Berlin, Munich and Hamburg). Hamburg was by far the most expensive, often as much as 10-20% more expensive.

The existing project was a great inspiration and helped me figure out the mTLS stuff. I totally get your mixed feelings, though.

I really like your suggestion. I will put it in an issue and look into that. https://github.com/yannick-cw/korb/issues/4

		Just to be clear, my mixed feelings don't come from a moral standpoint. Just hoping they don't lock it down any further heh ;-)

		Oh nice, thank you. Will check it out later! What I suspect though: They mainly show current discounts. The REWE API exposes those as a separate list for each market. There's around 3.5k markets and each can set their own discounts and has their own product catalogue with their own pricing. So it would be 3.5k API calls to fetch all offers for all markets. Which is doable. But fetching all products takes like 100 calls per market. It's quite a bit of data. And I think most supermarket don't publish their catalogue at all since they don't have delivery options.

		2.8 rating in Play Store sounds bad

I'd settle for just being able to sort items by unit price... I'm sure this is a [regulation-]solved problem in Germany though

An aggregator like this that could surface the same good for the cheapest price all inclusive of delivery would be something I would pay for!
