Obviously the word "anything that you can achieve ..." in your quote is an exaggeration. It is quite obvious that fintech wants to simplify the banking process to basic daily procedures most of the people need (like money transfer and accounting), and ignore the rest. It won't be the first FinTech doing so and it won't be the last. But it is one where "we want to have a high quality API" is the unique selling point.
