Preview - Count distinct launchers active for one tool within a time range

Preview: This endpoint is currently in a preview state and is subject to breaking changes without warning.

Preview endpoint. This endpoint is in preview: its request and response shapes may change without a version increment. A v2 of this API is planned to supersede it, targeting 2026-11.

For a single tool, returns the number of distinct launchers that recorded any activity within the time range. The count is derived from device_tool_launcher_hourly filtered to tool_id and is a distinct count over the window (not additive across sub-ranges).
A tool with no launcher activity in the window returns 200 with a count of 0; this endpoint does not distinguish an unknown tool_id.

Path Params
string
required
Query Params
date-time

Absolute inclusive UTC start timestamp (RFC3339). Must be paired with end; cannot be combined with range.

date-time

Absolute exclusive UTC end timestamp (RFC3339). Must be paired with start; cannot be combined with range.

string
^\s*(?:\d+w)?\s*(?:\d+d)?\s*(?:\d+h)?\s*$

Relative look-back duration composed of optional weeks (w), days (d), and hours (h) segments, in that order (e.g. 24h, 7d, 1w, 1w2d3h). Resolved server-side to [now-range, now). Mutually exclusive with start/end. Defaults to 24h when no time parameters are supplied.

string
Defaults to UTC

IANA timezone name (e.g. America/New_York, Europe/Paris) used to express the resolved range. For the stats endpoints it aligns day and week bin boundaries to that timezone's local midnight / start-of-week before the window is normalized to UTC for querying. Has no effect on endpoints that do not bucket by time. Defaults to UTC when omitted.

Headers
uuid
required
^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$
