Poll with [Query video task](/en/api-reference/common/query) and read `result.video_url` when completed. ## Model | `model` | Alias | Billing key | Duration | Resolution | | - | - | - | - | - | | `omni-10s` | `omni-flash-10s` (normalized to `omni-10s`) | `omni-10s` | Fixed **10** seconds | Fixed **720p** | Billing is `per_task`. Check the [model catalog](/en/api-reference/common/model-catalog) and the create response `cost` for live prices. ## Constraints * Aspect ratio: `16:9` or `9:16` only; default `16:9` * `duration` / `seconds` may be omitted; if set, must be `10` * Resolution is fixed at `720p` * Reference audio is **not** supported * These modes are **mutually exclusive**: * Text-to-video (`prompt` only) * Reference images (max **7**) * Reference videos (max **7**; cannot mix with reference images) * First/last frames (`first_image` required; `last_image` optional; cannot mix with reference images/videos) Reference media must be public `https://` URLs. ## Request body | Field | Type | Required | Description | | - | - | - | - | | `model` | string | yes | `omni-10s` (or alias `omni-flash-10s`) | | `prompt` | string | yes | Generation prompt; cannot be empty | | `aspect_ratio` / `ratio` | string | no | `16:9` or `9:16` only; default `16:9` | | `duration` / `seconds` | int \| string | no | Fixed **10**; may be omitted | | `images` / `reference_images` | string\[] | no | Reference images, max **7** | | `videos` / `reference_videos` | string\[] | no | Reference videos, max **7** | | `first_image` | string | conditional | First-frame URL for frame mode; required when using a last frame | | `last_image` | string | no | Last-frame URL; use together with `first_image` | ## Examples ### Text-to-video ```bash theme={null} curl -X POST 'https://sigrunai.com/v1/videos' \ -H 'Authorization: Bearer sk_xxx' \ -H 'Content-Type: application/json' \ -d '{ "model": "omni-10s", "prompt": "A golden retriever running across a sunny meadow, cinematic tracking shot", "aspect_ratio": "16:9" }' ``` ### First and last frames ```bash theme={null} curl -X POST 'https://sigrunai.com/v1/videos' \ -H 'Authorization: Bearer sk_xxx' \ -H 'Content-Type: application/json' \ -d '{ "model": "omni-10s", "prompt": "Smooth push from close-up to wide shot with natural lighting", "aspect_ratio": "9:16", "first_image": "https://example.com/first.jpg", "last_image": "https://example.com/last.jpg" }' ``` Success response: ```json theme={null} { "code": 20000, "msg": "提交成功", "data": { "task_id": "vid_xxxxxxxx", "status": "queued", "progress": 0, "model": "omni-10s", "cost": 0, "result": {} } } ``` `cost` is the charge for this task in credits; use the live response value. ## Polling ```bash theme={null} curl -X GET 'https://sigrunai.com/v1/videos/vid_xxxxxxxx' \ -H 'Authorization: Bearer sk_xxx' ``` See [Query video task](/en/api-reference/common/query) for status values.
