Which is not very open, it just means it's open to other companies. If I want my own data there is no api for me.
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.
