# Get Data Summary

`GET /api/v1/users/{user_id}/summaries/data`

Returns per-user data counts grouped by series type, event type, and provider.

Optionally scope the counts to a date window via `start_date` / `end_date` (data points are
filtered by `recorded_at`, events by their start time). Omitting both returns all-time counts.

## Path parameters

- `user_id` string, uuid, required

## Query parameters

- `start_date` string, date-time, nullable — ISO 8601 datetime (e.g. `2023-11-07T05:31:56Z`) or Unix timestamp in seconds. Date-only strings (e.g. `2023-11-07`) are also accepted and normalized to midnight UTC.
- `end_date` string, date-time, nullable — ISO 8601 datetime (e.g. `2023-11-07T05:31:56Z`) or Unix timestamp in seconds. Date-only strings (e.g. `2023-11-07`) are also accepted and normalized to midnight UTC.
