Submit a long video (YouTube, Twitch, Vimeo, Rumble, Zoom, Dailymotion) for clipping. Consumes 1 video from your monthly quota — check katto_get_usage first. Clips are produced asynchronously; returns a job id, then poll katto_get_job until status is 'completed'. Fails if the URL is unsupported or the video is over 90 minutes.

Read-only. Get the status, progress and clips of a job by id. Clips come ranked by virality score (0-100, highest first; ties broken by clip_index). Each clip is { url, captions_url, title, score, clip_index, hd }: when status is 'completed' every url is a finished, downloadable clip; hd is true once the 1080p high-quality render is ready. hd=false does NOT mean broken — the url already works, the 1080p is just still rendering in the background (and stays the standard render on the free plan). The job-level hd_ready flag turns true once every clip is hd, i.e. the URLs are final and won't be swapped again (status='completed' fires earlier). Returns 404 for an unknown id.

Read-only. List your recent jobs, newest first. Paginate with 'cursor' (pass the previous next_cursor); optional 'status' filter. Returns { jobs: [{id, status, source, created_at, completed_at}], next_cursor }.

Read-only convenience: the clips of a job as { url, captions_url, title, score, clip_index, hd }, ranked by score (highest first). hd=true means the 1080p render is ready; hd=false means the url is the standard render (HD still finishing, or the free plan). Empty until the first clip is ready.

Read-only. Your current plan and monthly video quota: { plan, videos_used, videos_limit, videos_remaining }. Call before katto_create_clip_job to confirm remaining quota.

Read-only. The transcript of a completed job as timestamped segments [{ start, end, text }]. Returns 404 while the job is still processing.

Cancel a still-running job (queued/processing) and refund the video back to your monthly quota. Safe to retry (idempotent). Returns an error if the job already finished, failed, or was cancelled.

Read-only. The account behind this key: plan, this key's scopes (read/write), and monthly quota { videos_used, videos_limit, videos_remaining }.

Read-only. The video platforms Katto can clip from, each with an example URL. Use it to confirm a URL is supported before calling katto_create_clip_job.

Read-only. The valid values for the optional config.clipLength on katto_create_clip_job (target clip-duration buckets). Note: clipLength is fixed at creation and cannot be changed by re-render.

Read-only. The valid caption_style preset names for katto_rerender_clip (id + label), e.g. 'hormozi' for bold word-by-word highlight. Call this before re-rendering so you pass a real preset instead of guessing.

Re-render one already-finished clip with a new reframe layout and/or caption style (get valid caption_style values from katto_list_caption_styles). Free — does NOT use video quota. Each call starts a new render (not idempotent); the original clip is kept. Returns a rerender_id; poll katto_get_rerender for the new clip url.

Re-render one finished clip dubbed into one or more of 8 languages (en, es, fr, it, pt, hi, ja, zh). Free — does NOT use video quota. Each call starts a new render (not idempotent). Returns a rerender_id; poll katto_get_rerender for the result.

Read-only. Poll a re-render started by katto_rerender_clip or katto_dub_clip. Returns { status, clip_url, captions_url } — clip_url is null until status is 'completed'.

Read-only. Your saved brand kits (colors, caption font and position, default layout, watermark url).

Read-only. Returns your webhook signing SECRET — treat it as a credential (do not display or log it) — plus how to verify Katto's signed completion callbacks (HMAC-SHA256 of {timestamp}.{body}). Pass webhook_url on a job to receive them.
