{/* Generated by scripts/generate-api-reference.mjs from data/api-reference.json. Do not edit. */}

Returns YouTube video caption list or caption content for a specific language. Optional inputs: `format`, `video_id`, `video_url`, `language_code`. Returns _code (caption language list). Supports multiple caption format outputs.

- **Tool id:** `tikhub-api-youtube-web-v2-get-video-captions`
- **Provider:** [TikHub](/providers/tikhub)
- **Job:** [Get video captions api youtube web v2](/reference/jobs/api-youtube-web-v2-get-video-captions) (`api.youtube.web-v2.get-video-captions`)
- **Price:** $0.008 per call. A call that fails at the provider costs $0.

## Inputs

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `format` | string | no | Caption format. Example: "srt" |
| `language_code` | string | no | Language code, returns available caption list if empty. Example: "en" |
| `video_id` | string | no | Video ID. |
| `video_url` | string | no | Video URL. Example: "https://www.youtube.com/watch?v=dQw4w9WgXcQ" |

## Output

Shape of the run's `result`, the expected shape, not yet checked against real answers:

```txt
{ code, data: { format, content, video_id, language_code, language_name }, docs, time, params: { format, video_id, video_url, language_code }, router, message, support, cache_url, time_zone, message_zh, request_id, time_stamp, cache_message, cache_message_zh }
```

## Run it

Every call needs your API token in `LOOOT_TOKEN`; [Sign in](/get-started/sign-in#use-the-token-in-scripts-and-agents) shows how to get one. Each run also needs a new idempotency key, so a retry never pays twice. With `wait: 30` the answer comes back inline when the run ends within 30 seconds. Otherwise you get the running run back: poll `GET /v1/runs/<runId>`.

To let looot pick among every provider of this job instead, send `job:api.youtube.web-v2.get-video-captions` as `endpointId`; see [the job page](/reference/jobs/api-youtube-web-v2-get-video-captions).
