Endpoint
GET/v1/youtube/videos/trendinglive · proven1 creditParameters
Query parameters
| Name | Required | Description | Example |
|---|---|---|---|
region | no | ISO-3166 region code (default US; maps to regionCode) | US |
category | no | videoCategoryId to restrict the chart | 10 |
language | no | Localized text language (maps to hl) | en |
max_results | no | Requested page size, 1–50. The paid primary defaults to 50; the source may return fewer. Keep an explicit size unchanged while paginating. | 50 |
cursor | no | Opaque page token from a previous response | CAUQAA |
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. | 1 |
judgments | no | Add bounded AI labels to eligible returned records (default on). off preserves the original data shape. Unclassified records remain present; labels depend on evidence, time, capacity and the existing request budget. No label surcharge. | on |
label | no | Set none to disable labels; default enables the endpoint’s label set. Equivalent to judgments=off. | none |
label_evidence | no | Include exact supporting sentences and zero-based sentence indexes when a label has validated evidence. No extra charge or change to decisions. | 1 |
exclude | no | Optionally remove confidently labelled engagement bait. Uncertain and unclassified records stay; removed IDs and an owner-bound recall reference are returned. | engagement_bait |
fit | no | Use goal to replace confidently irrelevant records with recall stubs. Keeps first, last, relevant and uncertain records; preserves order. Full evidence is stored for 24 hours when available. | goal |
goal | no | Required with fit=goal: describe the task in at most 600 characters. Supplied text is task context, never permission to act on posts. | Find concrete product complaints |
tokens | no | Optional soft response target for fit=goal, 256–32000. Safety and evidence retention take priority, so the returned result may exceed it. | 4000 |

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.

}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.

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
