supadata（supadata 分析）

Troubleshooting

If requests fail, run zero doctor check-connector --env-name SUPADATA_TOKEN or zero doctor check-connector --url https://api.supadata.ai/v1/transcript --method POST

How to Use

All examples below assume you have SUPADATA_TOKEN set.

The base URL for the API is:

• https://api.supadata.ai/v1

Authentication uses the x-api-key header.

1. Get YouTube Video Transcript

Extract transcript from a YouTube video:

Write to /tmp/supadata_url.txt:

https://www.youtube.com/watch?v=dQw4w9WgXcQ

curl -s "https://api.supadata.ai/v1/transcript" -H "x-api-key: $SUPADATA_TOKEN" -G --data-urlencode "url@/tmp/supadata_url.txt" -d "text=true"

Parameters:

• url: Video URL (required)
• text: Return plain text (true) or timestamped chunks (false, default)
• lang: Preferred language (ISO 639-1 code, e.g., en, zh)
• mode: native (existing only), generate (AI), auto (default)

2. Get Transcript with Timestamps

Get transcript with timing information:

curl -s "https://api.supadata.ai/v1/transcript" -H "x-api-key: $SUPADATA_TOKEN" -G --data-urlencode "url@/tmp/supadata_url.txt" -d "text=false" | jq '.content[:3]'

Response format:

{
  "content": [
  {"text": "Hello", "offset": 0, "duration": 1500, "lang": "en"}
  ],
  "lang": "en",
  "availableLangs": ["en", "es", "zh"]
}

3. Get TikTok/Instagram/X Transcript

Extract transcript from other platforms:

# TikTok
curl -s "https://api.supadata.ai/v1/transcript" -H "x-api-key: $SUPADATA_TOKEN" -G --data-urlencode "url@/tmp/supadata_url.txt" -d "text=true"

# Instagram Reel
curl -s "https://api.supadata.ai/v1/transcript" -H "x-api-key: $SUPADATA_TOKEN" -G --data-urlencode "url@/tmp/supadata_url.txt" -d "text=true"

10. Crawl Website (Async)

Start a crawl job for multiple pages.

Write to /tmp/supadata_request.json:

{
  "url": "https://example.com",
  "maxPages": 10
}

Then run:

# Start crawl
JOB_ID="$(curl -s "https://api.supadata.ai/v1/web/crawl" -X POST -H "x-api-key: $SUPADATA_TOKEN" -H "Content-Type: application/json" -d @/tmp/supadata_request.json | jq -r '.jobId')"

echo "Job ID: ${JOB_ID}"

# Check status
curl -s "https://api.supadata.ai/v1/web/crawl/<your-job-id>" -H "x-api-key: $SUPADATA_TOKEN" | jq '{status, pagesCompleted}'

Status values: queued, active, completed, failed

Response Handling

Synchronous (HTTP 200): Direct result returned.

Asynchronous (HTTP 202): Returns jobId for polling:

{"jobId": "abc123"}

Poll the job endpoint until status is completed.

Guidelines

1. Use mode=native to save credits: Only fetches existing transcripts
2. URL encode parameters: Use --data-urlencode for URLs
3. Check available languages: Response includes availableLangs array
4. Handle async responses: Some requests return job IDs for polling
5. Max file size: 1GB for direct file URLs
6. Supported formats: MP4, WEBM, MP3, FLAC, MPEG, M4A, OGG, WAV
