To provide me with API access to my own accounts, Era goes through another third party provider which again connects to my bank. I guess they could eventually get direct connections themselves.
So instead of me get convenient read-only access to my bank, I've ended up giving two separate third party providers credentials I'd prefer they didn't have.
All I'd need was an automated way to get a CSV or JSON dump of my transactions and I'd have been happy, but none of my banks support that without manually logging in. It's infuriating.
