# List annotations

> Lists the project's annotations together with platform annotations, which apply to every project.
Paginated; sorted by `createdMs` (default descending).

Filter by `kind` (repeat the parameter for several kinds); without it all kinds are returned.

`fromDate` and `toDate` select a window in project time. A period is returned when it overlaps the
window, an event when its date lies inside it. Annotations without a date and follow-ups (whose date says
when they become ready) are always returned.

Required API key permission: `observe:annotations:read`.

        Lists the project's annotations together with platform annotations,
