Agent pitfalls & tips
- Quota is unit-based, NOT request-based. Search costs 100 units!
- Use 'part' parameter wisely — each part (snippet, statistics, contentDetails) adds quota cost.
- API key works for all public data — no OAuth needed for reading.
- Upload requires resumable upload protocol for reliability.
- Analytics API is separate: youtubeAnalytics.googleapis.com.
