That basically describes the Google shopping ribbon that appears with searches for products. When Google was good, you'd say a website doesn't exist if you can't find it in the 1st page of Google. The shopping ribbon provides offers from websites that aren't on the first page of my search result. Although I don't think you can pay without visiting the seller's website, this means that these are effectively stores that are more visible through the APIs they use to talk to Google's recommender engine. These suggestions are also no doubt personalized.

This also describes adsense, or Amazon or AliExpress, so it is clearly a successful model. If there is much left of other models. The only thing we have to hopeful about is that the interface is standardized so commodified SWE can be used to make your own Amazon or AliExpress.

I'm currently building something like this, basically converting every service to a standardized API that you can consume in a structured manner. Not focused on AI, but focused on normal users with special requirements on usability.

Basically the ad blocking approach has failed, and one needs to recognize that an allow-list based approach is needed when consuming internet-based offerings. Pick the cherries out of each website, leave the trash behind, and then build a custom per-website GUI around the things that you actually want to consume.

I feel like this is a bit too-optimistically describing an outcome which is unlikely, given how consumers have been slowly losing the same war for decades already.

The elephant in the room and the really "tricky part" involves powerful advertising and copyright-holding companies. They will (continue to) interpret that kind of user-agency as an existential threat. Their businesses revolve around deciding and knowing what you actually see and do with your computer, and their toolkit isn't just technical, but also economic and political.

That's why we already have problems with DRM, "felony contempt of business model" under the DMCA, browser fingerprinting, and everybody surrendering to arbitrary JS code controlling their computer. We capitulate not just to see an article or talk to a friend, but also to avoid our technical details getting into a secret un-appeal-able "suspicious" blacklist.

You shouldn't need LLM and AI to do such things. Even if such things might be useful to some people, I might want to use the API without LLM/AI and just to read the API documentation and then to make my own, and some other people might want to do similarly. In the specific case of e-commerce, I had been making my own specification of a file format for e-commerce (which is independent of the protocol), which is not intended to use with LLM/AI, but instead is intended to avoid many kind of dishonest business while also being flexible and that you could make and use your own software or some other implementaiton instead of being forced to use their UI/UX.

Not sure if companies would ever want this. They rely on their dark patterns and intentional manipulations to get customers to do what they want.
