Spans

Get span summary

Changed on Oct 21, 2026

Returns aggregate span statistics for a time range. Send start_time, end_time, and environment as query parameters, and additional filters in the JSON body. Fields such as log_type are not read from query parameters. Empty or omitted filters may use pre-aggregated data; non-empty filters query individual spans using the List spans filter format.
