Technical details
Endpoint
GEThttps://toolsmith-api.dassad10.workers.dev/t/youtube/transcript?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the full spoken content of a YouTube video as clean plain text — especially for feeding into LLMs for summarization, Q&A, or analysis. It requires no YouTube API key and automatically de-duplicates caption artifacts. Prefer it over manual caption extraction or YouTube Data API when you want a pay-per-use, zero-setup solution that handles cleaning automatically.
Side effects
- Video ID or URL not found — returns error if the video does not exist or is private
- No captions available — returns error if the video has no captions or subtitles enabled
- Invalid input — returns error if the 'v' parameter is missing or malformed
- Rate or payment issues — call fails if the $0.01 USDC x402 payment is not completed successfully
- Region-restricted videos may fail if captions are not accessible

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
