# List Sessions

`POST /tracing/sessions/query`

> **Deprecated.**

List distinct session IDs from span attributes.

Returns the distinct values of `ag.session.id` across spans in the
current project, in a windowed, cursor-paginated form. Use this to
drive a session-picker UI before drilling into the spans of each
session.

The `realtime` flag controls the cursor field:

- `false` or unset — paginate by a stable `first_active` cursor
  (safe to iterate under heavy write load).
- `true` — paginate by `last_active`, reflecting ongoing activity
  but less stable between pages.

The response includes a `windowing` cursor; pass it as `windowing.next`
on the next call to continue.

## Request body

- SessionsQueryRequest — Request body for `POST /tracing/sessions/query`.
