Description
Capslane gives developers a stable API for YouTube transcripts. It returns native captions when available and automatically generates a timestamped transcript when they are missing. Get plain text or structured segments, choose a language, manage API keys, inspect usage, and connect through JavaScript, Python, MCP, or n8n. Start with 50 free requests each month.

Could you build this?
Partial While fetching YouTube captions and wrapping Whisper is conceptually clear, keeping YouTube scrapers working at scale against aggressive bot blocks and IP bans requires non-trivial anti-scraping infrastructure.
What it would actually take: The service needs a Node/Python API backend integrated with rotating residential proxy pools to bypass YouTube's IP blocks and throttling when extracting internal caption tracks. When captions are missing, it requires an asynchronous worker queue (Celery/BullMQ) with headless stream downloaders (yt-dlp) and GPU-accelerated speech-to-text nodes (Whisper/Faster-Whisper) before formatting unified millisecond-level timestamp payloads.
