Looks interesting, might implement this on a project soon.
Their pricing is a bit iffy though... " The Face++ APIs are currently provided free of charge. However, Face++ may charge fees for future use of or access to the Face++ APIs or the Face++ services according to its sole discretion. If Face++ decides to charge for the Face++ APIs Services, Face++ will provide you prior notice of such charges. Face++ may also charge You when providing You a service different from the service under these Terms; for example, we may charge additional fees for excessive API use. "
not even a rough clue given as to how much they'll charge (could be reasonable, or very expensive)...
