You could have json-available-p that simply tested one of json.c primitives to be fboundp, and if so, tried to invoke one of them on a trivial input to see if it signals an error. Alternatively, we could do this like decompress.c does: it would require the test for availability to be slightly more complex: (and (fboundp 'json-available-p) (json-available-p)) Would that be good enough?
