Output Schema
| Field | Type | Description |
|---|---|---|
id | string | Unique identifier for the generation task |
status | string | Task status: pending, running, completed, failed, timeout |
model | string | Model used for the generation |
outputs | array | Array of output items |

Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read

Wan 2.1 VACE Pose
Wan 2.1 VACE Pose is a Wan-family route for pose-controlled video generation. Wan’s video-focused generative architecture models appearance and time together, so supplied references, structural conditions, masks, speech, or written scene direction can influence a coherent sequence rather than a collection of unrelated frames. This exact route concentrates that architecture on its named production task.
Use the route when the available source material and final brief specifically require pose-controlled video generation. Identify every subject or condition, explain the intended action or transformation, and describe camera behavior, pacing, environment, lighting, atmosphere, and preservation constraints. This separates creative intent from the local duration, resolution, and delivery fields documented below.
Highlights
- Pose-guided movement. Uses a pose sequence to direct body position and action over time.
- Motion transfer. Carries articulated movement into a newly rendered subject or scene.
- Temporal anatomy consistency. Maintains recognizable body structure across the controlled sequence.
- Appearance freedom. Allows style, clothing, lighting, and environment to change around the pose condition.
Pricing
| Resolution | Billing unit | Price |
|---|---|---|
| auto | Per generated second | $0.040 |
| 240p | Per generated second | $0.040 |
| 360p | Per generated second | $0.040 |
| 480p | Per generated second | $0.040 |
| 720p | Per generated second | $0.080 |
When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The project needs this exact named workflow | The intended task belongs to another media route |
| All required reference or control media is available | Necessary assets or rights are unavailable |
| The brief can state transformation and preservation goals | Output must be deterministic at pixel or frame level |
| Supported duration, resolution, and format fit delivery | Final placement requires unsupported specifications |
| An asynchronous generated result fits production | A live frame-synchronous response is mandatory |
Prompt Guide
Identify the primary subject and every source or condition, state the intended transformation or action, then describe composition, camera or viewpoint, lighting, materials, pacing, atmosphere, and exact preservation requirements. Refer to multiple inputs in their schema order.

"prompt": "A precisely directed composition with explicit subject, transformation, camera or viewpoint, lighting, material, and preservation requirements",
