A lot of banks offer OFX access, it's what stuff like Money and Quicken talk to. It's mostly read only, although I think there are a couple of banks that can do bill pay over OFX. This is pretty common knowledge if you're writing this kind of software. Some vendors, like Ameritrade use different credentials for OFX. Mint/Yodlee asked for front door passwords and security answers that give them the ability to trade securities and empty my account, rather than the OFX id/pin that would give them access to a standard API to retrieve transactions and balances. This made me seriously doubt their competence, and I never became a customer. See http://en.wikipedia.org/wiki/Open_Financial_Exchange http://en.wikipedia.org/wiki/Open_Financial_Exchange for details.
