# List tasks

> Newest first. Live tasks by default; `archived=true` for the archived ones instead. `status` (repeatable), `agent_id`, `job_id` and the `created_gte` / `created_lte` bounds (ISO 8601, inclusive) narrow the list. For a count, send `limit=1&include=total_count` and read `total_count`.
