On success you receive a `task_id`. Poll [Query Video Task](/en/api-reference/common/query) until completed, then read the video URL from `result.video_url`. This shares the same endpoint as other Seedance routes: `POST /api/open-api/v1/seedance/videos`. The `model` field selects the route. ## Model | Route | Request `model` | Billing model name | Billing | Resolution | | ------------ | --------------------- | ---------------------------------- | ------------ | --------------- | | Mini Special | `seedance2.0-mini-sp` | `seedance2.0-mini-sp-{resolution}` | **per-task** | `480p` / `720p` | `{resolution}` only supports `480p` and `720p` (default), set via the `resolution` field. ## Billing * **Per-task**: cost = unit price of the billing model in the console (e.g. `seedance2.0-mini-sp-720p`). * `duration` is still required by the upstream (4–15 seconds, default 5) but does **not** affect billing. ## Request fields | Field | Type | Required | Description | | ------------------ | --------- | -------- | ------------------------------------------------------------- | | `model` | string | Yes | Must be `seedance2.0-mini-sp` | | `prompt` | string | Yes | Text prompt | | `duration` | int | Yes | Seconds, 4–15 (default 5) | | `resolution` | string | No | `480p` or `720p` (default) | | `ratio` | string | No | Aspect ratio, e.g. `16:9`, `9:16`, `1:1` | | `images` | string\[] | No | Reference images | | `first_image` | string | No | First frame image | | `last_image` | string | No | Last frame image | | `reference_videos` | string\[] | No | Reference videos | | `reference_audios` | string\[] | No | Reference audio; must be paired with images, video, or frames | ## Constraints * `images` and `first_image` / `last_image` **cannot** be used together. * `reference_audios` cannot be used alone; pair with images, reference video, or frames. ## Example ```bash theme={null} curl -X POST 'https://www.jimmyai.cn/api/open-api/v1/seedance/videos' \ -H 'Authorization: Bearer sk_xxx' \ -H 'Content-Type: application/json' \ -d '{ "model": "seedance2.0-mini-sp", "prompt": "A model rotates to show clothing details.", "duration": 10, "resolution": "720p", "ratio": "9:16", "images": ["https://example.com/ref-1.jpg"] }' ``` ## OpenAPI ````yaml POST /api/open-api/v1/seedance/videos openapi: 3.1.0 info: title: Jimmy AI OpenAPI description: API for Jimmy AI video generation services version: 1.0.0 servers: - url: https://www.jimmyai.cn description: Production server security: - bearerAuth: [] paths: /api/open-api/v1/seedance/videos: post: summary: Create Seedance Video Task description: >- Create a Seedance 2.0 video task.
