How this service works
Pay-per-call e-commerce, product, price and social media data tools for AI agents, from public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.
Output
Returns a JSON object containing: the video's metadata (id, title, channel name, channel ID, view count, length in seconds), the selected caption track (language code, name, whether auto-generated), a list of all available caption languages, an array of timed segments (each with start time in seconds, duration in seconds, and text), the full joined transcript text, the source URL, and a checkedAt timestamp. Videos without captions return an empty segment list; private or removed videos return 404; YouTube bot-check failures return 503 (not charged).
Example use cases
Summarize a long lecture video
“Get me the full transcript of this YouTube lecture — https://www.youtube.com/watch?v=dQw4w9WgXcQ — in English so I can summarize the key points.”
Extract quotes from a product review
“Pull the captions from this YouTube product review video at youtu.be/abc123XYZ45 — I want to find every time they mention battery life.”
Translate a foreign-language video
“Fetch the Spanish captions from this YouTube video — https://www.youtube.com/watch?v=xyz987uvw12 — so I can translate them into English.”
Technical details
Endpoint
GEThttps://api.shopsocial-api.workers.dev/api/social/youtube-transcript?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the spoken content of a specific YouTube video as structured text, especially when you require timestamps for each caption segment, want to prefer human-edited captions over auto-generated ones, or need to know which caption languages are available. It is ideal for summarization, quote extraction, translation pipelines, accessibility tooling, or any workflow that treats video content as text. Prefer it over screen-scraping or generic caption tools because it explicitly handles YouTube's caption track selection logic and returns rich metadata alongside the transcript.
Side effects
- Video has no captions — returns empty segments array
- Private or removed video — returns HTTP 404
- YouTube bot-check triggered — returns HTTP 503 (not charged, safe to retry)
- Requested language not available — falls back to the first available track
- Invalid or malformed video ID/URL — request fails with an error
- Auto-generated captions only when human captions are requested — auto-generated track returned as fallback
