# Generate a video

`POST /videos/generate`

## Request

- Base URL: `https://api.crevio.co/v1`
- URL: `https://api.crevio.co/v1/videos/generate`
- Auth: API key in header `Authorization`

Submits an asynchronous video generation job to the fal.ai queue and returns the queued job immediately. Poll `GET /v1/jobs/{id}` or `GET /v1/videos/{id}` for status and results. Credits are charged only when the job completes successfully.

## Headers

- `Idempotency-Key` string

## Request body

- VideoGenerateRequest
  - `model` string, required: A quality tier (fast, balanced, quality) or any fal.ai video endpoint id. Prefer a tier — it tracks the best current model for that price point. Required: video bills per second, so there is no default. `GET /v1/videos/models` maps tiers to ids with live pricing.
  - `input` object, required: Model-specific input, forwarded to fal verbatim. `prompt` is required.
    - `prompt` string, required: Text prompt describing the video to generate.
    - `duration` integer: Clip length in seconds (model-dependent, e.g. 5-10).
    - `aspect_ratio` string: Aspect ratio, e.g. 16:9, 9:16, 1:1.
    - `image_url` string: Source image URL for image-to-video models.
