not really, I worked on making this for another company. Reading is the simpler side of the story, the complex one is navigating the banking websites to be able to fill this in, and to maintain graceful degradation incase bank websites change

Indeed. You notice a variant of this with Plaid based integrations, common with roboadvisors to let you see a full-spectrum view of your accounts. The integrations which are based on the major banks that likely have tons of traffic fare okay. But if you've got 401ks from an employer provider that doesn't have a ton of traffic, you're in for some completely broken ugliness and no real major working protocol for your downstream applications to use.

I'm curious in particular about one thing you said, which is graceful degradation. What kinds of graceful degradation are you thinking about here?
