## youtube/video/audio

`GET /v1/youtube/video/audio`

The audio-only streams the platform offers for a video: format tag, direct time-limited link, MIME type, bitrate, sample rate, channels and duration. Links expire; fetch them promptly.

*YouTube video audio streams*

| Parameter | Required | Description |
| --- | --- | --- |
| `url` | yes | Video URL or id — e.g. `https://www.youtube.com/watch?v=dQw4w9WgXcQ` |
| `dry_run` | no | Read a zero-credit estimate without fetching sources, running AI, or reserving credits. Cache status is a snapshot, not a guarantee at execution. — e.g. `1` |

**Cost:** 1 credit at list price per successful uncached response; variable-cost operations may quote or settle a different charge. Confirmed uncharged or refunded failures report zero. Pending reconciliation can report credits_used:null; retain request_id and the original idempotency key.
