YouTube API endpoint
Use Crawlora's List transcript languages for a YouTube video API to extract supported public YouTube data as structured JSON. This page includes request parameters, cURL examples, response schema, error behavior, credit cost, and a Playground link for testing before integration.
/youtube/transcript/{id}/languagesReturns the transcript languages exposed by YouTube for a specific video. Developers commonly use this endpoint for data enrichment, monitoring, research dashboards, internal automation, and AI-agent workflows that need repeatable structured public web data. Authentication uses the documented Crawlora headers, and usage is metered with the credit cost shown on this page.
Request parameters are generated from the active endpoint catalog. Required values must be sent before Crawlora can call the upstream public web data source.
| Parameter | Type | Required | Default | Description | Example |
|---|---|---|---|---|---|
| id (path) | string | Yes | YouTube video ID (11-character code) | ||
| x-api-key (header) | string | Yes | API key required |
curl -X GET "https://api.crawlora.net/api/v1/youtube/transcript/dQw4w9WgXcQ/languages" \ -H "x-api-key: $CRAWLORA_API_KEY"
Send your scraping API key in the x-api-key header. Use the console API Keys page to rotate or select the active key.
Endpoint usage is metered in credits. The plan prices, included credits, limits, and overage rates below match the active backend billing configuration.

|---|---|---|---|---|---|
| Free | $0/mo | 2,000 | 500 daily credits | 5/min | No overage |

This endpoint is executed through Crawlora's managed scraping infrastructure.
Some targets require real browser execution because the data is loaded through JavaScript, dynamic rendering, or interaction-like browser behavior.
For supported endpoints, Crawlora can route requests through a managed browser cluster. This allows Crawlora to execute JavaScript, load dynamic content, apply browser-level request behavior, and normalize the rendered result into JSON.
You do not need to operate your own Playwright, Puppeteer, Chrome, proxy, queue, or retry infrastructure.
Crawlora does not silently return bad data when the upstream page cannot be used.
| Status | Common failure case |
|---|---|
| 400 | Invalid input or missing required parameter |
| 429 | Plan or endpoint rate limit exceeded |
| 500 | Internal execution error |
| 502 | Upstream platform failed, returned unusable HTML, or served a challenge page that could not be resolved |
When possible, Crawlora returns structured error context so your integration can retry, back off, or inspect the request.
