List runs of a DAG, most recent first.

Get a single DAG run by dag_id and dag_run_id.

List DAGs with their pause state, schedule, owners, and tags.

Get a single DAG's details by dag_id.

List DAG import errors (parse failures), with filename and stack trace.

The quickest way to find why a DAG is missing from the list or broken.

Read the log for one task attempt.

Task logs can be large, so by default only the trailing portion is returned (where the error and traceback usually are).

Return the Airflow version reported by the API.

Handy for confirming connectivity and which Airflow major version is in use.

Return Airflow component health: metadatabase, scheduler, triggerer, dag-processor.

List worker pools with their slot usage (occupied/running/queued/open).

List task instances in a DAG run, with their states and timings.

Get a single task instance by dag_id, dag_run_id, and task_id.

Trigger a new run of a DAG.

Pause or unpause a DAG.

Clear task instances so they re-run (retry).

Clearing resets task state and the scheduler re-runs them, so it is destructive - it can re-execute work. Use dry_run=True first to preview exactly which task instances would be affected without changing anything.
