YouTube API
YouTube video audio streams
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.

Response fields and example
This example is illustrative, not a captured live response. Variable-cost operations may settle a charge different from the list price below. A successful response puts the platform payload in data and reports the exact credits used, remaining balance, request id and cache status beside it.
{
"success": true,
"platform": "youtube",
"endpoint": "/v1/youtube/video/audio",
"data": {

}The example is illustrative and shows a documented subset of data. The fields below are optional across supported sources; nullable fields can also be absent. Preserve unknown values and accept additional fields.
Schema basis: observed response shapes, not an exhaustive field specification. See schema coverage and validation limits.
Download the data JSON Schema. Validate response.data, not the whole envelope. A valid shape does not establish that every field or source record was returned.
| Field inside data | Type | Meaning |
|---|---|---|
count | number | null | Number of records in this response, not lifetime or total matches. |
has_more | boolean | null | Source continuation indicator; null means unknown. |
items | array | null | Returned records. Source coverage and completeness vary. |
items[].audio_channels | number | null | Optional audio channels supplied by this operation. Null means unknown. |
items[].audio_quality | string | null | Optional audio quality supplied by this operation. Null means unknown. |
items[].audio_sample_rate | number | null | Optional audio sample rate supplied by this operation. Null means unknown. |
items[].average_bitrate | number | null | Optional average bitrate supplied by this operation. Null means unknown. |
items[].bitrate | number | null | Optional bitrate supplied by this operation. Null means unknown. |
items[].content_length | number | null | Optional content length supplied by this operation. Null means unknown. |
items[].duration_ms | number | null | Optional duration ms supplied by this operation. Null means unknown. |
items[].itag | number | null | Optional itag supplied by this operation. Null means unknown. |
items[].last_modified | string | null | Optional last modified supplied by this operation. Null means unknown. |
items[].mime_type | string | null | Optional mime type supplied by this operation. Null means unknown. |
items[].quality | string | null | Optional quality supplied by this operation. Null means unknown. |
items[].url | string | null | Original source URL when supplied. |
note | string | null | Optional note supplied by this operation. Null means unknown. |
url | string | null | Original source URL when supplied. |
video_id | string | null | Optional video id supplied by this operation. Null means unknown. |
Optional fields reviewed from preserved successful responses. Additive fields and source variations remain allowed; validate the fields your workflow requires.
The example is invented and illustrates types only; zero and empty values are not claims about a real result.
Failures use the typed error envelope. A confirmed uncharged or refunded failure reports zero; a pending reconciliation can report an unknown charge. Read credits_used and error.details.billing_status, and keep request_id for recovery. Response contract · Error reference
