## When to prefer this

Choose this endpoint when you need to extract spoken text from a YouTube video and want a straightforward, pay-per-call transcription service without managing your own speech-to-text infrastructure. It is well-suited for single video transcription tasks billed at a fixed per-call rate. Prefer this over self-hosted solutions when simplicity and low setup overhead matter more than bulk pricing.

## Known failure modes

- Invalid or inaccessible YouTube URL — video may be private, deleted, or region-locked
- Video has no spoken audio or only music/background sound — transcript may be empty or poor quality
- Video longer than supported duration may require multiple calls or may fail
- YouTube rate limiting or access restrictions may cause retrieval failures
- Non-English or multilingual audio may produce degraded transcription quality

## Output

A text transcript of the spoken audio content from the specified YouTube video, capturing the words spoken throughout the video. The response includes the extracted spoken text, billing for approximately 4 minutes of audio per API call.
