What you can build with this model
Real-world workflows and production use cases you can build and ship with this model.
Animate any photo with the Happy Horse 1.0 API
Pass a first-frame image and a motion prompt. The Happy Horse 1.0 API returns a 3 to 15 second clip from the same endpoint as your text-to-video calls — no model swap.
Generate a clipCompose fresh scenes from reference images
Send 1 to 9 reference images alongside a prompt. The Happy Horse 1.0 API fuses subject, style, and props into a brand-new scene — product shots, character reskins, stylized social posts.
Restyle existing footage without re-shooting
Pass video_url to the Happy Horse 1.0 API and the source motion stays intact — only the look changes. Combine with up to 5 style images and audio_setting=origin to keep the original soundtrack.

Why reAPI
One endpoint, four modes
The Happy Horse 1.0 API auto-routes T2V, I2V, R2V, and EDIT by request shape. Routing priority is video_url > first_frame_image > image_urls > prompt-only. No model swap, no second integration.
Pricing by resolution × seconds
The Happy Horse 1.0 API is billed per-second × resolution. See current 720P and 1080P rates in the pricing table on this page. Mode does not change the rate, and failed jobs refund automatically.
Native audio in edit mode
Set audio_setting=origin to retain the source soundtrack or auto to regenerate audio. The Happy Horse 1.0 API ships voiced clips without a separate TTS step.
