What do you mean "an API"?  Application Program Interface ??  Anyway 
your line solves my problem perfectly:

$ for parameter_name in ${(k)parameters[(I)var*]} ; do set ${parameter_name}=; done

... arbitrary list of variables all nulled.  This could be useful for 
cleaning up after some messy function.

Many thanks.
