# Get Run Status

GET https://api.onepin.ai/api/v1/workflows/{workflow_id}/runs/{run_id}/status

Lightweight run status for progress polling.

Returns only the volatile, frequently-changing fields: `status`, step
counts (`total_steps`, `finished_steps`), timestamps (`started_at`,
`completed_at`, `paused_at`, `pause_requested_at`), `usage_summary`,
`error`, and `has_export`. The definition snapshot is intentionally
omitted to keep response size small.

Recommended polling pattern: call `GET /runs/{run_id}` once after
starting a run to load the immutable definition snapshot and initial
metadata, then poll this endpoint until `status` reaches a terminal value
(`completed`, `failed`, or `cancelled`). `has_export` becoming `true`
signals that a download is ready via `GET /runs/{run_id}/download`.

The transient `pausing` state is observable here: `status == "running"`
with `pause_requested_at` set means a pause is in progress but the
current wave has not yet finished draining.

## Request

### Path parameters

- `workflow_id` (string, required)
- `run_id` (string, required)

### Headers

- `X-Workspace-Id` (string, optional, nullable)

## Response

### 200

Successful Response

- `data` (WorkflowRunStatusOut, required)
- `meta` (Meta, required)

## Errors

Validation Error

- `detail` (list of ValidationError, optional)

## Types

### WorkflowRunStatusOut

- `id` (string, required)
- `workflow_id` (string, required)
- `status` (string, required)
- `run_number` (integer, required)
- `token_cost` (integer, required)
- `created_at` (datetime, required)
- `updated_at` (datetime, required)
- `total_nodes` (integer, optional, default: 0)
- `total_steps` (integer, optional, default: 0)
- `finished_steps` (integer, optional, default: 0)
- `finished_nodes` (integer, optional, default: 0) — Graph nodes that have reached a terminal state, judged by each node's highest-iteration step, so a retried node counts once. Pair with total_nodes for 'N of M completed'. A node interrupted by an automatic pause does NOT count while parked (its step is cancelled with a hard recovery checkpoint and is reopened in place on resume), so that kind of pause neither inflates the count nor drops it on resume. A partial-recovery resume schedules a NEW iteration for the node, so the count can drop by one until that iteration finishes. finished_steps counts rows and never excludes the parked row.
- `held_nodes` (list of HeldNodeOut, optional, nullable) — Nodes the run is parked in front of, each with the locales it will process. Meaningful while status == 'paused'; cleared to null on resume and RETAINED on a run cancelled while paused. Null (never []) also means never computed: a run paused before this field shipped, or one parked straight from 'pending'. [] means it WAS computed and nothing is held. Excludes nodes skipped by an upstream discard and a node interrupted mid-execution by an automatic pause (that one is visible as its own cancelled step).
- `usage_summary` (map from string to any, optional)
- `started_at` (datetime, optional, nullable)
- `completed_at` (datetime, optional, nullable)
- `pause_requested_at` (datetime, optional, nullable)
- `paused_at` (datetime, optional, nullable)
- `paused_ms` (integer, optional, default: 0)
- `pause_reason` (enum, optional, nullable) — Why the run is paused or draining toward an automatic pause. Manual pauses use user; null when no pause is active.
  - Allowed values: `user`, `provider_outage`, `provider_rate_limited`, `provider_billing`, `node_timeout`
- `pause_error` (string, optional, nullable) — Aggregate customer-facing explanation for an automatic pause. Null for manual pauses and separate from terminal error.
- `error` (string, optional, nullable)
- `has_export` (boolean, optional, default: false)
- `triggered_by` (TriggeredByOut, optional, nullable) — Actor that triggered a workflow run. ``user_name`` is guaranteed non-empty: derived from ``donut.utils.user.user_display_name`` which falls back to ``email`` when both first/last names are empty (``email`` is NOT NULL on User).

### Meta

- `request_id` (string, required)
- `timestamp` (datetime, required)

### ValidationError

- `loc` (list of ValidationErrorLocItems, required)
- `msg` (string, required)
- `type` (string, required)
- `input` (any, optional)
- `ctx` (ValidationErrorCtx, optional)

### HeldNodeOut

One node the run is parked in front of — it has no step row yet.

- `node_id` (string, required)
- `locales` (list of string, optional) — Locales of the lines this node will process once the run resumes. Empty means render no language line.

### TriggeredByOut

Actor that triggered a workflow run. ``user_name`` is guaranteed non-empty: derived from ``donut.utils.user.user_display_name`` which falls back to ``email`` when both first/last names are empty (``email`` is NOT NULL on User).

- `user_id` (string, required)
- `user_name` (string, required)

### ValidationErrorLocItems

### ValidationErrorCtx
