## When to prefer this

Choose this endpoint when you need YouTube video metadata without a Google/YouTube API key or quota constraints, want to avoid account setup, need pay-per-call pricing at $0.05 USDC, or require localized video data by country and language. Prefer over the official YouTube Data API when avoiding subscription overhead or API key management is important.

## Known failure modes

- Invalid or non-existent video ID returns an error or empty response
- Invalid country/language codes may return default results or an error
- Expired or invalid next_page_token causes pagination failure
- YouTube page structure changes may break scraping temporarily
- Rate limiting or IP blocking by YouTube may cause intermittent failures
- Payment failure (insufficient USDC) blocks the request via x402 protocol
