Unfortunately neither of these work in the US. Salt Edge supposedly supports US banks but when I reached out to them a few weeks ago (specifically for the purpose of using them with Firefly III) this was their reply:

Though in this case I’d likely lay the blame entirely upon the US banks themselves. For example, to my knowledge, Bank of America has no way to retrieve any of my transactions or data without letting an app impersonate me using my login information, which I’m not about to do.
