katto_create_clip_jobSubmit a long video for clipping, either by public link in url (YouTube, Twitch, Kick, Vimeo, Zoom, Google Drive, Dropbox, Loom, LinkedIn, Facebook, Rumble, Dailymotion, Medal.tv, or a direct https link to a video file; Google Drive and Dropbox links must be shared publicly) or, for a local file, by upload_id after katto_upload_video and the PUT of the file. Pass exactly one of url or upload_id. 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 every 30-60 s until status is 'completed', or pass webhook_url to be notified (url jobs only). Pass idempotency_key when you might retry a url job, so a retry never spends a second video (an upload can only be started once anyway). Fails if the URL is unsupported, the uploaded file is missing, or the video is longer than your plan allows.katto_get_jobRead-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.katto_list_jobsRead-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 }.katto_get_clipsRead-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.katto_get_usageRead-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.katto_get_transcriptRead-only. The transcript of a completed job as timestamped segments [{ start, end, text }]. Returns 404 while the job is still processing.katto_cancel_jobCancel 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.katto_get_accountRead-only. The account behind this key: plan, this key's scopes (read/write), and monthly quota { videos_used, videos_limit, videos_remaining }.katto_list_sourcesRead-only. The link sources Katto can clip from (YouTube, Twitch, Kick, Vimeo, Zoom, Google Drive, Dropbox, Loom, LinkedIn, Facebook, Rumble, Dailymotion, Medal.tv, or a direct https link to a video file), each with an example URL. Use it to confirm a URL is supported before calling katto_create_clip_job; for a local file use katto_upload_video instead.katto_list_clip_lengthsRead-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.katto_list_caption_stylesRead-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.katto_rerender_clipRe-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.- +17 more on the listing page
Prompt To Asset tools 24
asset_capabilitiesReport which of the three execution modes this server can run RIGHT NOW given the current env: inline_svg (zero key — hosting LLM authors the SVG), external_prompt_only (zero key — paste prompt into Ideogram/Nano Banana/Midjourney/Recraft/Flux UIs, then asset_ingest_external), api (requires provider key). Read-only; no network. Call before offering the user options.asset_enhance_promptClassify an asset brief, route to the right model, rewrite the prompt in that model's dialect, and report which execution modes are available (inline_svg / external_prompt_only / api). Returns an AssetSpec JSON including modes_available, optional svg_brief (for inline_svg), optional paste_targets (for external_prompt_only), and — when the brief leaves a material ambiguity — a `clarifying_questions[]` array the host LLM should surface via AskUserQuestion (or the equivalent) BEFORE calling a generator. Each entry has {id, header, question, options[], required, why}. Read-only; idempotent; no network.asset_generate_logoGenerate a logo. Three modes: inline_svg (Claude emits SVG — zero key), external_prompt_only (returns prompt + paste targets — zero key), api (server runs the provider pipeline — requires key). Omit mode to auto-select. Returns an AssetBundle / InlineSvgPlan / ExternalPromptPlan discriminated by the mode field.asset_generate_app_iconGenerate an app icon (iOS AppIconSet, Android adaptive, PWA maskable, visionOS 1024² master + placeholder parallax layers). Three modes (inline_svg / external_prompt_only / api). In non-api modes only the master mark is produced; call asset_ingest_external afterwards to run the platform fan-out. Set ios_18_appearances=true to also emit dark and tinted 1024² variants for iOS 18 tintable icons.asset_generate_faviconGenerate a favicon bundle (favicon-{16,32,48}.png + icon.svg + icon-dark.svg + apple-touch + PWA 192/512/512-maskable + <link> snippet). Three modes — inline_svg is the best fit for simple glyph marks (legible at 16×16).asset_generate_og_imageRender a 1200×630 OG image via Satori template (deterministic typography, no diffusion). Default mode=api renders server-side without any API key. external_prompt_only is only meaningful when with_background_image is set. inline_svg is not supported (web-font loading + precise text layout beyond LLM reach).asset_generate_illustrationGenerate one or more brand-locked illustrations. Two modes (external_prompt_only / api); inline_svg is not supported — path budget too small for a composed scene. Injects brand bundle (palette, style_refs, LoRA, style_id) where supported.asset_generate_splash_screenGenerate a cross-platform splash-screen bundle from a brand mark. Two modes (external_prompt_only / api); inline_svg is not supported (splash screens are PNG bundles — generate a logo inline_svg first, then call this with existing_mark_svg). api mode composites the mark onto background_color and emits ios/LaunchScreen-2732.png, android/mipmap-*dpi/splash.png, android/themes-splash.xml, pwa/splash-1200.png, and a README describing how to wire each.asset_generate_heroGenerate marketing-hero / landing-page banner art. Two modes (external_prompt_only / api); inline_svg is not supported. Accepts aspect_ratio (16:9 / 21:9 / 3:2 / 2:1). Injects brand bundle where supported. Returns N variants if count>1.asset_remove_backgroundMatte an image to transparent background (BiRefNet / BRIA RMBG / U²-Net via remote endpoint; local white-chroma fallback). Returns RGBA PNG path.asset_vectorizeConvert a raster image to SVG. Tries in order: Recraft /vectorize (if PROMPT_TO_BUNDLE_RECRAFT_VECTORIZE_URL is set), vtracer on PATH, potrace on PATH, then a built-in posterize run-length fallback. Passes all output through SVGO when installed.asset_upscale_refineUpscale / refine an image, asset-type-aware. DAT2 for flat logos/icons, Real-ESRGAN/SUPIR for photoreal, img2img for diffusion polish. Lanczos fallback.- +12 more on the listing page
