The limit to only daily pulls and up to 180 days of historical data is pretty disappointing. Would expect Stripe to push the envelope here and move down to near-instant updates and full historical data. This is basically a knockoff of existing solutions done at par or worse which is surprising to see from a company like Stripe. Maybe they've lost a bit of their magic or focus. Will be interesting to see how everyone adapts and improves to this announcement.
since they are heavily based on existing aggregators, they are limited by the lowest common denominator (if a good chunk of e.g. Yodlee-scraped credit unions only support 180 days, then that's a limiting factor for everyone).
I would expect they will gradually improve and cut out other aggregators and replace with direct connections that have more & better data as they go along.
Or maybe not, because with Oauth they then become at the mercy of the bank that issues the token (banks can revoke tokens or attach individual conditions on what data is accessed and how much).
