# Get the generated video

> Returns the generated video. Video outputs are retained for ~24 hours after generation; after that the endpoint returns `410 Gone` with `code: output_expired`. If the generation never produced an output (status `failed`, `cancelled`, `moderation_rejected`, or polling-timeout `expired`), this endpoint returns `422 Unprocessable Entity` with `code: output_not_available` — check `GET /v1/images/{id}` for the failure reason (the generation lookup endpoint accepts both `img_*` and `vid_*` IDs; there is no `GET /v1/videos/{id}`).

Range requests (`Range: bytes=…`) are answered with `206 Partial Content` so HTML5 `<video>` seeking works.

Authentication: send a Bearer JWT or `X-Api-Key` header, OR pass the short-lived signed `?token=` query param the API mints when it serves the video URL. The signed-token path lets browser `<video>` tags load the URL without custom headers.



## OpenAPI

````yaml /api-reference/openapi.json get /v1/videos/{id}/output
openapi: 3.0.0
info:
  title: Aurous Labs API
  description: >-
    Generate AI images with custom LoRA styles.


    ## Authentication

    All requests require an API key passed in the `X-Api-Key` header.

    Create API keys in your
    [dashboard](https://app.aurous-labs.com/dashboard/api-keys).


    ## Closed-beta access gate

    API keys are scoped to a user. If that user's account is not approved for
    the closed beta, every request returns `403` with one of these `error.code`
    values:


    - `account_pending` — awaiting review

    - `account_rejected` — declined post-signup

    - `account_suspended` — was approved, then suspended


    There is no retry — contact support to be approved. The same codes are
    emitted by the WebSocket gateway via 4001 close.


    ## Common headers

    Every response carries `Aurous-Request-Id` (a server-minted `req_<ULID>` for
    support tracing) and `Aurous-Version` (the API version applied to the
    response). Optionally pin a version on the request with `Aurous-Version:
    YYYY-MM-DD` — defaults to your team's pinned version.


    ## Quick Start

    ```bash

    curl -X POST https://api.aurous-labs.com/v1/images \
      -H "X-Api-Key: al_live_your_key" \
      -H "Content-Type: application/json" \
      -d '{"prompt": "A golden sunset over mountains", "lora_id": "your-lora-id", "size": "2k_1_1"}'

      Drop-in raw passthrough for Seedance video generation. Point the official
      Seedance provider SDK at this API's base URL and authenticate with your
      Aurous API key in the `X-Api-Key` header — request bodies are forwarded to
      the provider verbatim and responses come back shape-identical, so you keep
      the provider's exact request/response shapes. Task ids are Aurous-native
      `vid_…` ids. Billing rides response headers, not the body:
      `Aurous-Credits-Held` on the create response and `Aurous-Credits-Charged`
      on a settled, succeeded task read — the body itself stays provider-shaped.
