I mean every api/app/website has a different way to do this. If there was a standardized api that everyone could conform to to allow this automation I would be all for it. I assume 1p does this by writing custom code/rules for dealing with the most popular sites out there and then erroring out for anything else.

AI could potentially help solve those unpopular site/app/whatever edgecase.
