# Evaluate whether a source video can be cloned reliably

> Runs a synchronous, deterministic cloneability analysis of a staged source video and returns a verdict (strong, possible, or weak), a 0-100 score, and the evidence behind them, so the agent can branch on the result, for example stopping on a weak verdict. The videoUrl must be public HTTPS and staged first: provider CDNs cannot fetch TikTok or Instagram links directly, so download the source with /v1/videos/download/tiktok or /v1/videos/download/instagram before checking it. The source video must be at most ~2 minutes long. Shares the daily clone admission limit.

  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. The pipeline runs end to end in about 5 minutes, measured. Kling
    motion control is the default video model; Seedance is the alternate. Clone
    video output is 480p 9:16.
