# Media · Generate · Poll a video generation job (step 3 of 3)

GET https://api.simplified.com/api/v1/ai/video/{art_id}/variations/{variation_id}

Step 3 — poll this endpoint after `generateVideo`. Read `job_status`:

- **Non-terminal**: `CREATED`, `PENDING`, `PROCESSING`, `RENDERING`,
  `UPDATED` — keep polling. 10s is a reasonable interval.
- **Terminal**: `DONE` (success — `payload.output` and
  `asset_references` are now populated with the rendered video URL)
  or `FAILED` (error — inspect `payload.errors`).

Generation is webhook-driven (FAL / Kie call back into djapp when
rendering finishes), so the row updates asynchronously — there is
no `task_id` to short-circuit polling.

## Authentication

- `Authorization` header (required) (prefixed with ` Api-Key   `) — Header authentication of the form `Api-Key  <token>`
- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `art_id` (string, required) — AiImageArt UUID returned as `id` from `generateVideo`.
- `variation_id` (string, required) — AIArtVariation UUID returned as `art_variation_id` from `generateVideo`.

## Response

### 200

AIArtVariation record.

- `id` (string, optional) — AIArtVariation UUID.
- `job_status` (enum, optional) — Lifecycle state of an async generation job. Terminal: `DONE` (success), `FAILED` (error). All other values are non-terminal — keep polling.
  - Allowed values: `CREATED`, `PENDING`, `PROCESSING`, `DONE`, `FAILED`, `RENDERING`, `UPDATED`
- `modified` (datetime, optional)
- `payload` (map from string to any, optional) — Variation payload. Key sub-fields: - `input` — the request that produced this variation (`model`, `capability`, and all parameter values). - `output` — populated once `job_status="DONE"`; contains the generated asset references / URLs. - `errors` — populated on `job_status="FAILED"`. - `reserved_quota_id` — internal credit reservation marker.
- `output` (map from string to any, optional) — Convenience expansion of `payload.output` with resolved asset URLs. Populated only when `job_status="DONE"`.

## Errors

### 401 Unauthorized Error

Unauthorized.

- `any`

### 404 Not Found Error

Variation not found.

- `any`
