## When to prefer this

Choose this endpoint when you need to programmatically extract the spoken content of a YouTube video as machine-readable JSON, particularly for downstream tasks like summarization, translation, search, or analysis. Prefer it over manual transcription tools when you need structured, timestamped output quickly and cost-effectively at $0.08 per call.

## Known failure modes

- Invalid or malformed YouTube URL/ID provided — returns parse or validation error
- Private, age-restricted, or geo-blocked video — transcript may be inaccessible
- YouTube rate-limiting or API changes breaking transcript access — service error
- Very long videos may produce extremely large JSON payloads
