Wan 2.7 Image to Video
Animate your own picture. image becomes the first frame; add end_image and Wan 2.7 interpolates the motion between the two. Clips run 2–15 seconds, optionally driven by an audio track.
Fields
| Field | Type | Default | Notes |
|---|---|---|---|
prompt | string, required | — | Up to 50,000 characters. |
image | image URL, required | — | First frame. JPEG, PNG, or WebP URL. |
end_image | image URL | — | Optional last frame. |
audio | audio URL | — | Optional WAV/MP3 URL that drives speech or rhythm. |
duration | 2–15 | 5 | Output length in seconds. |
aspect_ratio | 16:9 / 9:16 / 1:1 / 4:3 / 3:4 | — | Omit to follow the input image. |
resolution | 720p / 1080p | 720p | Sets the per-second rate. |
seed | integer | random | Fix it to compare prompt changes. |
Billing
You pay for output seconds: $0.10 at 720p and $0.15 at 1080p, the same as Alibaba's list price. Input images and audio are not metered.
| Output | 720p | 1080p |
|---|---|---|
| 2s | $0.20 | $0.30 |
| 5s (default) | $0.50 | $0.75 |
| 10s | $1.00 | $1.50 |
| 15s | $1.50 | $2.25 |
Failed runs are not charged.
Prompting
- Describe what moves, not what is already visible: “the bus pulls away as rain starts and umbrellas open”.
- With two frames, keep framing and lighting compatible or describe the transition explicitly.
- Leave
aspect_ratiounset to keep the image's own proportions.
Limits
- One start image and one optional end image per request; for multi-subject references use
alibaba/wan/2.7/reference-to-video.

Create a SandBase API key and set it in your server environment. All requests use Bearer authentication.
export SANDBASE_API_KEY="YOUR_API_KEY"Keep the key on your server. Do not expose it in browser code or commit it to a repository.
3. Queue
Submit a request
POST to /v1/run with this model ID and its inputs. The request example above includes submission and polling.
Fetch request status and result
Use the returned run ID to poll until the status is completed, failed or timeout. Read output only after completed.
curl "https://api.sandbase.ai/v1/run/$RUN_ID" \
-H "Authorization: Bearer $SANDBASE_API_KEY"4. Files
Hosted files
Pass a publicly accessible file URL in the model’s image, video or audio field. Supported formats and limits are shown beside each Playground input.
Uploading images
Use the upload or replace control on supported image fields in the Playground. Video URL fields accept a hosted driving video; they do not imply video-upload support.
