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": "meta_ads",
"endpoint": "/v1/meta_ads/ad-transcript",
"data": {
"platform": "meta_ads",
"id": "example-ad",
"transcript": "Illustrative spoken words.",
"has_transcript": true
},
"credits_used": 5,
"credits_remaining": 99,
"request_id": "req_…",
"cached": false
}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: reviewed response shaper. 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 |
|---|---|---|
platform | string | null | meta_ads |
id | string | null | Source identifier. Preserve its exact string value; do not convert large IDs to numbers. |
transcript | string | null | Source transcript, when available. |
has_transcript | boolean | null | Whether usable text was returned. |
_warnings | array | Collection limitations or component warnings. Read before interpreting coverage. |
A source 404 means the transcript is unavailable; it does not prove that the parent ad is non-video or lacks audio.
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
