Subtitles

Fetch YouTube video subtitles via TranscriptAPI.com.

Setup

If $TRANSCRIPT_API_KEY is not set, read references/auth-setup.md and follow the instructions there to get and store the key.

Required Headers

Every request needs two headers:

Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: your agent's name and version if known (e.g. HermesAgent/0.11.0, ClaudeCode/1.0). Version is optional — agent name alone is fine. Do not omit this header or send a bare default — Cloudflare will return a 403 (error code 1010) and block the request.

GET /api/v2/youtube/transcript

curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_URL&format=text&include_timestamp=false&send_metadata=true" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY" \
  -H "User-Agent: YourAgent/1.0"

Param	Values	Use case
`video_url`	YouTube URL or video ID	Required
`format`	`json`, `text`	`json` for sync'd subs with timing
`include_timestamp`	`true`, `false`	`false` for clean text for reading/translation
`send_metadata`	`true`, `false`	Include title, channel, description

For language learning — clean text without timestamps:

curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_ID&format=text&include_timestamp=false" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY" \
  -H "User-Agent: YourAgent/1.0"

For translation — structured segments:

curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_ID&format=json&include_timestamp=true" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY" \
  -H "User-Agent: YourAgent/1.0"

Response (format=json):

{
  "video_id": "dQw4w9WgXcQ",
  "language": "en",
  "transcript": [
    { "text": "We're no strangers to love", "start": 18.0, "duration": 3.5 }
  ]
}

Response (format=text, include_timestamp=false):

{
  "video_id": "dQw4w9WgXcQ",
  "language": "en",
  "transcript": "We're no strangers to love\nYou know the rules and so do I..."
}

Tips

Many videos have auto-generated subtitles in multiple languages.
Use format=json to get timing for each line (great for sync'd reading).
Use include_timestamp=false for clean text suitable for translation apps.
