Query parameters

daysdoubleOptionalDefaults to 7

the last days * 24 hours, when no start_date or end_date is sent

start_datestringOptionalformat: "date"

first day, UTC, inclusive (YYYY-MM-DD). Default: 6 days before end_date (a 7-day window). Sending either one replaces days

end_datestringOptionalformat: "date"

last day, UTC, inclusive (YYYY-MM-DD). Default: today. At most 366 days from start_date. Sending either one replaces days

start_timestringOptional

an exact start instead of start_date: unix seconds, or ISO 8601 in UTC (2026-10-10T10:00:00Z). start_date and end_date in the reply are then the UTC days the window touches. Sending either one replaces days

end_timestringOptional

an exact end (exclusive): unix seconds or ISO 8601 with Z. Default: now; never later than now. Must be after start_time. Sending either one replaces days

the index’s incarnation, an opaque string: it changes only when the index is deleted and created again (whose seqs start again at 1), or restored from a backup (whose seqs continue from the backup’s). Sent with X-Captain-Applied-Seq
