I can only consider modules that are either in luarocks (so that my
user does not need building skills) or in pure lua with a license that
allows me to include the code in my own distribution. There seem to
be quite a few of both kinds.

Even roll-my-own is likely to be adequate for the actual data, which
is generated by some PHP server and seems to consist of a one-element
list containing associative arrays. My fallback if the user does not
have a json module I recognize is

function json_decode(s)
  return { load('return '..s:match'%b[]':sub(2,-2):
    gsub('("[%w_-]-"):','[%1]='))() }
end

So far it has not failed :-)
