Choose this endpoint when you need pay-per-request YouTube transcript extraction with no subscription or API key required. Ideal for lightweight, occasional transcript fetching where you want to avoid YouTube Data API quotas or OAuth setup. Best for agents that need on-demand transcript access across multiple languages with a simple USDC micropayment model.

## Known failure modes

## How this service works
