Why don't banks sell API access at a rate s/similar/lower than Google Maps API access? This is starting to feel like music and video piracy all over again.
If all of your credit lines, checking, savings, and investment accounts were an API call away, the institutions providing those no longer build relationships that can be profitable; they're simply utilities you could swap out interchangeably. As such, they're not a fan of this idea.
It's sad, because that's exactly what they should be. :/.
