Count lookups over time

GEThttps://api.checkslip.com/api/slips/counts

API key

Lookups of this account per time bucket, split by outcome, for a chart. Counted by the time of the lookup (checked_at), the same axis as the lookup history table; Credit usage counts by the time the credit was settled, so the two do not always match. bucket is MINUTE, FIVE_MINUTE, FIFTEEN_MINUTE, HOUR, THREE_HOUR, SIX_HOUR, TWELVE_HOUR or DAY. At most 1,440 points per call; a window too wide for the bucket answers 400. Only time and outcome filter the counts; any other filter you send is listed in filters_ignored. Counts trail the table by about 2 minutes, see as_of. No credit is used. Needs an API key with slip:read.
