The happy path is genuinely a one-sitting build: the open-source youtube-transcript-api library fetches a caption track in a few lines, and wrapping it in FastAPI gives you a working personal endpoint. The honest gap is reliability. YouTube rate-limits and IP-blocks caption scraping at any real volume, so the DIY version works until it suddenly does not, and there is no fix without a rotating proxy pool you must rent and operate. The paid product is not selling the parsing; it is selling the unblocked pipe, plus search and playlist endpoints on top.

el prompt

Build me a small YouTube transcript API service, a personal stand-in for TranscriptAPI.
Requirements:
- Python 3.11 stack: FastAPI, uvicorn, and the youtube-transcript-api library; no
  database, one file plus a README is fine.
- GET /transcript?video=<id-or-url>: extract the video id, fetch the caption track,
  return JSON with the full text plus timestamped segments.
- Support lang= with a sensible fallback to the first available track, and report
  which track was actually used in the response.
- Clean JSON errors: 404 when captions are disabled or missing, 502 when YouTube
  blocks the fetch; never a bare 500.
- Read an optional comma-separated PROXIES var from .env and rotate per request;
  with none set, run direct.
- GET /health returning version and uptime.
- A tiny CLI example in the README: curl the endpoint, jq out the text.
- Keep it stateless and private: no accounts, no API keys, no telemetry, no storage.
- README must be honest about the failure mode: at any real volume YouTube
  rate-limits and IP-blocks caption fetches, and this build has no defense.
- Out of scope, deliberately: the rotating proxy pool and anti-blocking
  infrastructure, channel/playlist/search endpoints, bulk throughput, and SLAs.
  That reliability layer is the thing the paid product actually sells.

por qué la gente sigue pagando

The parse was never the hard part. Holding a durable, unblocked pipe into YouTube captions at volume is an operations problem that costs real money to run, and buying it for 5 USD a month is cheaper than renting proxies and babysitting them.
