It seems that my question is not so straightforward - I didn't think it would it could be problem to separate "public macros" (= public ConTeXt commands = these that are cited in manuals, on wiki or simply - which "you can use").

I haven't been following the answers closely as they seemed to focus on getting ALL commands.  So excuse me if this is too naive, but have you looked at the "quick reference"?:

http://pragma-ade.com/general/qrcs/setup-en.pdf

I think it does not contain all commands, however, not even all the "public" ones.  But maybe it's a good starting place.  It is based on

… tex/texmf-context/tex/context/interface/cont-en.xml

(There are ones for the other languages, too.)  The xml database contains the source file name, too, which helps me sometimes.  One could probably develop a quicker reference based on it in the format you asked for.
