supadata（supadata 分析）

Supadata — Platform-Agnostic Video Transcript & Metadata

Purpose: Extract transcripts and metadata from any supported social video URL — Instagram, TikTok, YouTube, Twitter/X, Facebook — without opening a browser.

Always use this BEFORE browser-use-cloud for any video URL.

What This Skill Does

Calls the Supadata API to:

1. Fetch transcript (spoken audio → text) from social videos
2. Fetch metadata (title, author, description, engagement, duration)
3. AI-extract structured data from a video (tools, prompts, workflows)

Supports: YouTube, Instagram, TikTok, Twitter/X, Facebook, direct video file URLs.

Trigger Conditions

Use this skill whenever:

• User shares a video URL (Instagram reel, TikTok, YouTube, X video, Facebook)
• User asks to "transcript", "transcribe", "watch", "digest", "summarize", "what does she say"
• User asks "what's in this video" or "extract from this reel"
• Any content ingestion task starting from a video link

Priority: Always try Supadata before browser-use-cloud.

Pre-Flight Check

echo "${SUPADATA_API_KEY:+SET}" || echo "MISSING"

If missing:

"I need SUPADATA_API_KEY. Add it to /root/.openclaw/.env and restart the gateway."

Auth header: x-api-key: $SUPADATA_API_KEY Base URL: https://api.supadata.ai/v1

Endpoints Reference

Transcript (primary — all platforms)

curl -s "https://api.supadata.ai/v1/transcript?url=<VIDEO_URL>&text=true" \
  -H "x-api-key: $SUPADATA_API_KEY"

• text=true → plain text (use by default)
• text=false → timestamped segments
• lang=en → optional language hint

If response has jobId (async):

curl -s "https://api.supadata.ai/v1/transcript/<jobId>" \
  -H "x-api-key: $SUPADATA_API_KEY"

Poll until status = done. Wait 3–5s between polls.

Metadata (all platforms)

curl -s "https://api.supadata.ai/v1/metadata?url=<VIDEO_URL>" \
  -H "x-api-key: $SUPADATA_API_KEY"

Returns: title, author, description, engagement metrics, thumbnail, duration.

AI Extract (structured data from video)

Use when you need structured output — extract tools, prompts, workflows:

curl -s "https://api.supadata.ai/v1/extract" \
  -X POST \
  -H "x-api-key: $SUPADATA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "<VIDEO_URL>",
    "prompt": "Extract all prompts, workflows, and tool names shown or mentioned in this video."
  }'
# Returns jobId → poll /v1/extract/<jobId>

YouTube-specific (better quality for YouTube)

curl -s "https://api.supadata.ai/v1/youtube/transcript?url=<YOUTUBE_URL>&text=true" \
  -H "x-api-key: $SUPADATA_API_KEY"

Platform Routing

Execution Protocol

1. Check API key — fail fast if missing
2. Detect platform from URL
3. Fetch metadata first — fast, often has description with full workflow text
4. Fetch transcript — plain text, async if jobId returned
5. If transcript fails → try /v1/extract with descriptive prompt
6. Deliver output → combine metadata + transcript
7. If user said "digest" → hand off to youtube-digest skill at Step 3

Fallback Chain

Supadata transcript → Supadata AI extract → browser-use-cloud → manual

Never skip to browser-use-cloud while Supadata paths are viable.

Output Format

**[Title]** — @[author] ([platform])

**Transcript:**
[full plain-text transcript]

**Metadata:**
- Duration: Xs
- Description: [text]
- Tags: [list]

Hard Rules

• Always Supadata first. Never browser for video URLs without trying this.
• If transcript unavailable → use /v1/extract before giving up.
• If video is non-English → return as-is, optionally translate.
• If jobId returned → poll to completion, don't return empty result.
• Always report which path was used (transcript / extract / fallback).
