Clipmaster promo

Skill clipmasterapp/skills/skills/clipmaster-promo

Produce a vertical promo video for any business with no source footage — scan a website URL for a grounded storyboard/script via ClipMaster Promo Studio, then optionally render a talking-head AI avatar video that speaks the script. Use when the user wants a promo video, launch video, or social ad for a website/product and has no existing footage.From its SKILL.md

ClipMaster Promo — website → promo script → avatar video

When there's no source video to clip, ClipMaster can produce content: Promo Studio scans a website and returns a grounded storyboard (real copy from the page, not hallucinated), and Avatar Studio turns a script into a talking-head video.

Setup (once)

User needs a ClipMaster account on a paid plan (Promo Studio & Avatar Studio are paid features; API keys require Pro/Business).
API key from https://clipmasterapp.com/api-keys in env var CLIPMASTER_API_KEY. Ask if missing — never invent one.
Base URL https://clipmasterapp.com, header Authorization: Bearer $CLIPMASTER_API_KEY.

Responses use { "ok": true, "data": ... } / { "ok": false, "error": "..." }.

Step 1 — Script a promo from a website

curl -X POST https://clipmasterapp.com/api/promo/generate \
  -H "Authorization: Bearer $CLIPMASTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://the-business.com"}'

Returns a grounded promo spec: scene-by-scene storyboard, voiceover script pulled from the site's actual value props, and a hero screenshot of the page. This call scans the live site and renders a headless screenshot, so it can take up to 60 s.

Show the user the storyboard and script before doing anything else — let them edit lines.

Step 2 (optional) — Render a talking-head avatar video

curl -X POST https://clipmasterapp.com/api/avatar \
  -H "Authorization: Bearer $CLIPMASTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"scriptText": "<the approved script>"}'

Optional fields: avatarId, voiceId, layoutId (omit for defaults). Generation is asynchronous — poll GET /api/avatar with the same auth header to list jobs and statuses; finished jobs include the video URL.

Errors & limits

401 invalid key · 402 UPGRADE_REQUIRED (needs paid plan) or insufficient credits · 429 rate-limited (avatar: 20/10 min; promo scans are concurrency-capped — wait and retry).
Promo scans only work on public https URLs (no localhost/internal hosts).
Avatar renders spend credits; confirm the script with the user before rendering.

Good defaults

Keep scripts 45–60 s spoken (~110–150 words).
Hook in the first sentence: a specific claim or number from the site, not a greeting.
One CTA at the end, matching the site's actual offer.
