I obviously need to do that.

However, one issue remains:  If somebody wants to use your API for 
another bus, he needs to know at which point he can successfully use it, 
and after what point (or context) it cannot, even must not, be used 
anymore.  This isn't documented --- or is it?

(By 'buses are enumerated before...' you surely mean only the buses for 
which you implemented this API usage already.)
