You really should provide some reasoning if you ask people to not voice their feature requests on Show HN. (FWIW, not having an API is a dealbreaker for a bookmarking service in my eyes)
The things was launched yesterday by a single person. Of course there will be an API, but do not ask for one as if it was the most important feature, the most needed, the most urgent one.
Also, when you ask for an API (I don't know if it was you who asked) you don't give some reasoning on why you think such feature is needed, so why are you asking me that?
