Up/down voting works the same. It's just the "how=" parameter that changes from "up" to "down".

There's also a "/flag" call with only "id" and "auth" to flag comments / articles. (with "un=t" it unflags) The link says "flag" or "unflag".

It's also worth noting that some comments cannot be downvoted.
