## youtube/videos/trending

`GET /v1/youtube/videos/trending`

The most-popular videos chart (videos.list chart=mostPopular) for a region and optional category.

*YouTube trending videos*

| Parameter | Required | Description |
| --- | --- | --- |
| `region` | no | ISO-3166 region code (default US; maps to regionCode) — e.g. `US` |
| `category` | no | videoCategoryId to restrict the chart — e.g. `10` |
| `language` | no | Localized text language (maps to hl) — e.g. `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. — e.g. `50` |
| `cursor` | no | Opaque page token from a previous response — e.g. `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. — e.g. `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. — e.g. `on` |
| `label` | no | Set none to disable labels; default enables the endpoint’s label set. Equivalent to judgments=off. — e.g. `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. — e.g. `1` |
| `exclude` | no | Optionally remove confidently labelled engagement bait. Uncertain and unclassified records stay; removed IDs and an owner-bound recall reference are returned. — e.g. `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. — e.g. `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. — e.g. `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. — e.g. `4000` |

**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.
