# List a YouTube video's caption languages, free

**Use case:** 

Find out which caption languages a video offers, manual or auto-generated, together with its title, channel and duration, without fetching a transcript. This run writes nothing to the dataset and is never charged.

```json
{
  "videoUrl": "https://www.youtube.com/watch?v=jNQXAC9IVRw",

  ],
  "targetLanguage": "en",
  "captionType": "any",
  "outputFormats": [],
  "listOnly": true,

## FAQ

### Where is the answer?

In the run's OUTPUT record (key-value store), since no dataset item is written and nothing is charged.

### What does it cost?

$0.0007 per delivered transcript ($0.70 per 1,000). No start fee, no per-run fee. A video without captions costs nothing.

### Does it work on every video?

Only public videos that have captions, manual or auto-generated. Private, removed and age-restricted videos cannot be read, and there is no audio transcription or translation.

## About this Actor

This example demonstrates how to use [Wicked YouTube Transcript Scraper API](https://apify.com/myworkingmemory/wicked-youtube-transcript-scraper-api.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/myworkingmemory/wicked-youtube-transcript-scraper-api.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
