# Enqueue a DAG-run from inline spec

`POST /dag-runs/enqueue`

Creates a DAG-run directly from a provided DAG specification (YAML) and enqueues it for execution.

This endpoint does not require a pre-existing DAG file; the supplied `spec` is parsed and validated
similarly to `/dags/validate`, and the run is persisted to the queue if valid.

## Query parameters

- `remoteNode` string

## Request body

- object
  - `spec` string, required — DAG specification in YAML format
  - `name` string — Optional name to use when the spec omits a name
  - `profile` string — Runtime profile override. Empty string means no profile.
  - `params` string — Parameters to persist with the queued DAG-run in JSON format
  - `dagRunId` string — Optional ID for the DAG-run; if omitted a new one will be generated
  - `queue` string — Override the queue to use for this DAG-run
  - `singleton` boolean — If true, prevent enqueuing if DAG is already running or queued (returns 409 conflict)
  - `labels` string[] — Additional labels to apply to the DAG-run (format: key=value or key-only). Merged with labels defined in the DAG spec. Mutually exclusive with deprecated `tags`; the server returns HTTP 400 if both are set.
  - `tags` string[] — Deprecated alias for Labels. Additional labels to apply to the DAG-run (format: key=value or key-only). Merged with labels defined in the DAG spec. Mutually exclusive with `labels`; the server returns HTTP 400 if both are set.

## Response `200`

DAG-run successfully enqueued

- object
  - `dagRunId` string, required — Unique identifier for the DAG-run. The special value 'latest' can be used to reference the most recent DAG-run.

## Other responses

- `400` — Invalid DAG spec or parameters
- `409` — DAG is already running or queued (singleton mode), or dagRunId already exists
- `default` — Generic error response
