Ask HN: Are you aware of any banks that offer a consumer API

I’m looking for a place to put my money that offers an API that I can consume with my own scripts. I don’t want to make a scalable app with something like Plaid. I just want to be able to pull down current balances and transaction history; I don’t want my API key to be able to transfer money external. Bonus points if I can open unlimited sub-accounts and make internal transfers between them. I’m happy to pay a modest fee for this service. Double bonus for existing mobile UI. Does something like that exist?
