> Anyone have any idea why banks are so closed-minded regarding opening up their data via APIs? 1. The data has a lot of value, you need to convince your bank that having a great API is worth more than more rigid control of your interaction (more to them, not to you). 2. As you say, regulatory/legal stuff can be a nightmare. 3. Most first-world banks' internal systems are a bit of a maze given they've been built up over 40 or more years. Making them work safely and sanely with letting anyone code apps against interfaces is not particularly trivial.
