I was coming to the comments to ask about this as I noticed a other (finance) companies [1] were providing this for free and I wanted to know what the game was about.
I thought this would be an AI app that would rely on the domain name and/or website crawl to infer an aesthetic, and then create a prompt that would be fed to a generative image transformer
It doesn't appear to work for google subdomains. For keep.google.com gives a very blurry google logo with the edges clipped off. For mail.google.com the result is a broken image link.
Not sure about stock tickers, but for domains it seems to pull an image from the <head> of a page. Looks like it's trying to find a favicon or the largest application image listed. Seems to skip some things like twitter's meta image tag, so maybe there's a preset list of tags it'll search for?
I would assume the favicom of the vast majority of domains online are not registered trademarks. And having a copy of a trademarked image isn't illegal in any country I know?
So it seems that you found a database of PNG images associated with stock tickers, and added favicon scraping, and then put it together with the false promise of "high resolution logos", when I get severely mixed results and a lot of errors when it can't handle a favicon.
I mean, it works, good job at that at least, but it doesn't work well and it doesn't seem useful.
