Comment (by karsten):

 Not easily. We only keep aggregate statistics of most frequent parameter
 combinations:

 {{{
 2018-07-24 13:46:11,543 Request statistics (2018-07-24 13:46:11, 3600 s):
 2018-07-24 13:46:11,544   Total processed requests: 40467
 [...]
 2018-07-24 13:46:11,544   Most frequently requested parameter
 combinations: [search, limit, type, fields] (21944), [lookup, fields]
 (18106), [lookup] (236)
 }}}

 So, at least we can say that at most 181 (= 40467 - 21944 - 18106 - 236)
 out of 40467 requests (0.58%) included the fingerprint parameter. Could
 also be 0, but we don't know for sure.

 What we could do is extend the statistics to include less frequent
 parameter combinations beyond the top 3 without giving a request count for
 privacy reasons. Then we'd at least find out whether the fingerprint
 parameter is used at all, over a day or two.
