The cheaper HappyHorse — the same image-to-video contract as 1.0 at a lower per-second rate.

Supported modes

Mode	Required input	Rules
Image to video	`model`, `prompt`, `images`	Required. This model publishes no text-to-video mode.
Multiple source images	`model`, `prompt`, `images`	Up to nine angles of the same subject.

Async flow: Create the task, save data.id, then poll the Task with GET /v1/tasks/{task_id}. On succeeded, read data.output.media. On failed, read data.error_code and data.error_message, then follow the error and retry policy.

Using a local file? upload a local input first and pass the returned data.url.
