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

Happy Horse Image to Video
Happy Horse Image to Video is a image-to-video workflow for turning supplied visual material and written direction into a new moving sequence. The source image establishes the subject, framing, and visual identity before the model introduces motion.
Use the route for rapid creative iteration when a key asset already exists and the goal is to extend, animate, or revise it. Describe subject action, camera behavior, timing, atmosphere, and the intended ending; local duration, resolution, aspect-ratio, and seed controls define the delivery envelope.
Highlights
- Still-to-motion creation. Animates an established image while retaining its visual foundation.
- Directed subject movement. Uses the prompt to define action, pace, staging, and interaction within the shot.
- Camera and atmosphere control. Lets the brief specify framing, camera movement, lighting, mood, and scene energy.
- Production-oriented delivery. Supports explicit duration, resolution, framing, and repeatability controls where exposed by the route.

When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The project needs creating a directed video sequence | The goal is a different media task or endpoint |
| The available inputs match the required local schema | Required source media or permissions are unavailable |
| The brief can specify subject, composition, style, and delivery | The result must be deterministic at pixel or sample level |
| The supported formats and controls match final placement | Delivery requires unsupported dimensions, codecs, or duration |
| An asynchronous generated result fits the workflow | A live, frame-synchronous, or real-time response is mandatory |
Prompt Guide
Write the request as a production brief: identify the main subject or source material, state the intended transformation, describe composition or timing, and finish with style, atmosphere, and delivery constraints. Keep preservation requirements separate from requested changes, and use only fields exposed by this route.
