  description: >-
    VidJutsu is a video API built for agents to operate directly. Your agent can
    clone viral trending skits now: stage a trending clip with
    /v1/videos/download/tiktok or /v1/videos/download/instagram, check it for
    cloneability, generate a character and a clean starting frame, then render
    the clone. Kling 3.0 Motion Control is the supported clone-video model and
    preserves the source soundtrack.
