# List Runs

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

List runs for a workflow, newest first by default.

Returns a counted, paginated list of runs for the specified workflow.
Each item includes the run's status, step progress (`total_steps`,
`finished_steps`), credit usage, and the actor who triggered it.

**Status filter:** Pass `?status=completed,failed` to OR-match multiple
statuses. Values must be the raw lowercase RunStatus strings. Unknown values
or empty tokens (e.g. `a,,b`) return 422.

**Pagination:** `pagination.total` reflects the filtered count. Sort
tiebreaks always append `id ASC` for stable offset/limit pagination.

For aggregate statistics (pass rate, average duration) across all runs,
use `GET /runs/summary` instead.

## Authentication

- `Authorization` header (bearer token, required) — Clerk JWT token
- `Authorization` header (bearer token, required) — Onepin live API key (`op_live_...`). Test and public keys are reserved in Phase 1.

## Servers

- `https://api.onepin.ai` (prod, default)
- `https://dev-api.onepin.ai` (dev)

## Request

### Path parameters

- `workflow_id` (string, required)

### Query parameters

- `offset` (integer, optional, default: 0) — Zero-based pagination offset.
- `limit` (integer, optional, default: 20) — Maximum items to return (1–100).
- `status` (string, optional, nullable) — Comma-separated raw RunStatus values (e.g. `completed,failed`). Values are case-sensitive lowercase: `pending`, `running`, `completed`, `failed`, `cancelled`, `paused`. Multiple values OR-match. Empty tokens (e.g. `a,,b`) and unknown values return 422.
- `search` (string, optional, nullable) — Case-insensitive search over the triggering user's display name (falls back to email).
- `sort` (enum, optional, default: created_at) — Sort field: `created_at` | `started_at` | `completed_at` | `status`. Defaults to `created_at`.
  - Allowed values: `created_at`, `started_at`, `completed_at`, `status`
- `order` (enum, optional, default: desc) — `asc` or `desc`. Defaults to `desc`.
  - Allowed values: `asc`, `desc`

### Headers

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

## Response

### 200

Successful Response

- `data` (list of WorkflowRunListItem, required)
- `meta` (Meta, required)
- `pagination` (CountedPaginationMeta, required) — PaginationMeta variant for endpoints that compute an unpaginated total.

## Errors

### 422 Unprocessable Entity Error

Validation Error

- `detail` (list of ValidationError, optional)

## Types

### WorkflowRunListItem

- `id` (string, required)
- `status` (string, required)
- `run_number` (integer, required)
- `created_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)
- `credits` (integer, optional, default: 0) — Credits debited from the user's spendable balance for this run; excludes invoiced overage.
- `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.
- `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).
- `output_line_count` (integer, optional, nullable)
- `delivered_audio_ms` (integer, optional, nullable)

### Meta

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

### CountedPaginationMeta

PaginationMeta variant for endpoints that compute an unpaginated total.

- `limit` (integer, required)
- `total` (integer, required)
- `next` (string, optional, nullable)
- `prev` (string, optional, nullable)

### ValidationError

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

### 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)
