It’s one step closer to have an agent to go shopping for my recipes or dinner, but hopefully unlike the Son of Anton

#22Nice! Do you know if the Austrian billa (REWE's subsidiary) is using the same api?

#23Surprised how little the B2C and even B2B e-commerce segment is providing API access for automation and agentic coding. One could easily set up rate limits, fraud detection and KYC checks upfront initial access.

#24I remember a friend and I in college were looking into ways to do this in the US but major grocery chains here are pretty sensitive about their product data being accessible by open APIs and web scraping...
It would have been a cool project!

B2B:
Look at chefkoch.de
They do use the REWE API, and I'm guessing not without their knowledge
B2C: Is it really surprising that a busines has no interest in providing more price transparency to their customers?

#26Cool 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 p…

What do you mean? The official REWE app and website provide just that.
> I'm sure this is a [regulation-]solved problem in Germany though
Not sure what you mean by that.

#27Serious good use of an AI. Just let them do the grey area (like repeated purchase). I'd even let an algo pick better groceries for me. Cools tuff!

When Amazon launches an API everyone cries. Same story over and over. Even better example: TakeAway-Group. The perfect MITM.

#29I want to add something else to this. In the process of writing this, I also played with formal verification and formally verified the suggestion engine, which was a really nice side discovery.
The basic idea is to write a prove in Lean4 and then test both the production implementation (Haskell) and the Lean implementation against random inputs. Compare if the results are the same.
If that is the case -> you can be pretty sure the unproven production version is as correct as the proven lean version.

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
