From 2017-01-17 - 2017-01-23 it looks like there were about 620K Action API hits involving the soft launched oresscores and oresreview enhancements (n.b., there was a status update in https://lists.wikimedia.org/pipermail/ai/2016-October/000106.html as work was underway).

$ hive --database=wmf
select count(1) from
webrequest tablesample (bucket 1 out of 10000 on rand())
where year = 2017
and month = 1
and day > 16 and day < 24
and uri_path = '/w/api.php'
and (uri_query like '%oresscores%' or uri_query like '%oresreview%');

62

There is also meta=ores although I guess that's not too interesting.
