From my understanding in recent years Mint uses a lot more of the Quicken/QuickBooks semi-formal APIs when formal APIs don't exist. My understanding is that is one of the few, biggest benefits of Mint being bought by Intuit because that 200-pound gorilla has always had a surprising number of special read only APIs and export dump tools from even the quirkiest, smallest banks because of how ubiquitous their tax software is (and how many users would rebel if they didn't have easy access in Quicken or QuickBooks).
