How this service works
Data APIs (leads, jobs, YouTube, Reddit, Trends, SEC, tenders...). POST JSON, pay per call in USDC on Base via x402. Charged only when results are returned.
Output
A JSON object with a count and an items array, where each item contains caption text (optionally translated), suggested hashtags, and metadata about the YouTube Short it was extracted from.
Example use cases
Repurpose competitor Shorts content
“Grab the captions from the 5 newest Shorts on the @MrBeast channel in English, add hashtags #viral and #shorts, and return up to 20 results — I want to study their scripting style.”
Multilingual caption translation for localization
“Fetch captions from these three YouTube Shorts URLs and translate them all into Spanish: https://www.youtube.com/shorts/abc123, https://www.youtube.com/shorts/def456, https://www.youtube.com/shorts/ghi789 — limit to 15 results.”
Hashtag-enriched captions for content scheduling
“Get the captions from the latest 3 Shorts from @NasDaily and @Kurzgesagt, add hashtags #science and #explainer, keep it to 10 results max, and give me English captions only.”
Technical details
Endpoint
POSThttps://2-29-135-242.sslip.io/x402/youtube-shorts-captions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract caption/subtitle text from YouTube Shorts at scale — especially when you need multi-channel aggregation, language filtering, translation, or hashtag enrichment in a single pay-per-result API call. Prefer it over manual YouTube scraping or the YouTube Data API when you want a simple POST interface with no OAuth setup and micro-payment billing.
Side effects
- Channel or Shorts URL not found or invalid — empty items array returned
- No captions available for requested language — falls back to any available language or returns empty
- YouTube rate limiting or access restrictions causing partial or no results
- maxItems or maxShortsPerChannel limits result in fewer results than expected
- Payment not processed — no charge and no results returned if USDC payment fails
