Parameters

Name	In	Type	Required	Description
start_time	body	integer	Yes	Start of the time range as a Unix timestamp in milliseconds. Must be at least 2020-01-01.
end_time	body	integer	Yes	End of the time range as a Unix timestamp in milliseconds. Must be at least 2020-01-01.
interval_seconds	body	integer	No	Bucket size in seconds. Each row in the response covers this many seconds of the selected time range. For example, pass 3600 for hourly buckets or 86400 for daily buckets. Whether `time_zone` shifts bucket boundaries depends on this value: whole-day multiples (e.g. 86400) align to local midnight; whole-hour multiples up to 24 hours (e.g. 3600, 14400) align to local hour boundaries from midnight; sub-hour values and other sizes remain UTC-anchored regardless of `time_zone`.
group_by	body	string[]	No	Request body field group_by.
filters	body	object[]	No	Request body field filters.
time_zone	body	string	No	IANA time zone identifier (e.g. 'America/New_York', 'Europe/London', 'UTC') used to align bucket boundaries for eligible `interval_seconds` values. Whole-day multiples start at local midnight; whole-hour multiples up to 24 hours align to local hour boundaries from midnight. Sub-hour intervals and other bucket sizes remain UTC-anchored regardless of this setting. Defaults to UTC.
