Plaid for Ecommerce

Holy shit

This looks interesting, can you explain more about what problem it solves and for who?

Cool idea, but I have questions about the legality of this. More than likely, this is doing a headless login using the users credentials on the various ecommerce sites (similar to what Plaid did in the early days to "login" to various banks). While it may not be explicitly banned in the terms for each of the sites, it's definitely a grey area.
