Basic Transcript Extraction (Python)

import requests API_KEY = "your_api_key" response = requests.post( "https://youtubetranscript.dev/api/v2/transcribe", headers={ "Authorization": f"Bearer {API_KEY}", "Content-Type": "application/json", }, json={"video": "dQw4w9WgXcQ"} ) data = response.json() for segment in data["data"]["transcript"]: print(f"[{segment['start']:.1f}s] {segment['text']}")

Basic Transcript Extraction (JavaScript/Node.js)

const response = await fetch("https://youtubetranscript.dev/api/v2/transcribe", { method: "POST", headers: { Authorization: `Bearer ${API_KEY}`, "Content-Type": "application/json", }, body: JSON.stringify({ video: "dQw4w9WgXcQ" }), }); const { data } = await response.json(); console.log(data.transcript);

Using the Node.js SDK

npm install youtube-audio-transcript-api import { YouTubeTranscript } from "youtube-audio-transcript-api"; const yt = new YouTubeTranscript({ apiKey: "your_api_key" }); // Simple extraction const result = await yt.getTranscript("dQw4w9WgXcQ"); // With translation const translated = await yt.transcribe({ video: "dQw4w9WgXcQ", language: "es", }); // Batch (up to 100 videos) const batch = await yt.batch({ video_ids: ["dQw4w9WgXcQ", "jNQXAC9IVRw", "9bZkp7q19f0"], });

Basic Transcript Extraction (cURL)

curl -X POST https://youtubetranscript.dev/api/v2/transcribe \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"video": "dQw4w9WgXcQ"}'

Batch Processing (up to 100 videos)

curl -X POST https://youtubetranscript.dev/api/v2/batch \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"video_ids": ["dQw4w9WgXcQ", "jNQXAC9IVRw", "9bZkp7q19f0"]}'

Translation

Add "language": "es" (or any ISO 639-1 code) to get the transcript translated: curl -X POST https://youtubetranscript.dev/api/v2/transcribe \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"video": "dQw4w9WgXcQ", "language": "es"}'

ASR Transcription (videos without captions)

For videos that don't have captions, use ASR with a webhook: curl -X POST https://youtubetranscript.dev/api/v2/transcribe \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"video": "VIDEO_ID", "source": "asr", "webhook_url": "https://yoursite.com/webhook"}' This returns immediately with status: "processing". Results are delivered to the webhook URL when ready. Poll with GET /api/v2/jobs/{job_id} if not using webhooks.

Error Handling

HTTP StatusError CodeDescription400invalid_requestInvalid JSON or missing required fields401invalid_api_keyMissing or invalid API key402payment_requiredInsufficient credits404no_captionsNo captions available and ASR not used429rate_limit_exceededToo many requests โ€” check Retry-After header

Important Notes

Always ask the user for their API key if they haven't provided one. Free keys are available at youtubetranscript.dev. Omitting the language parameter returns the best available transcript without translation (saves credits). ASR is async โ€” always use a webhook URL or poll the jobs endpoint. Batch endpoint accepts both YouTube URLs and 11-character video IDs. Re-fetching an already-owned transcript costs 0 credits.
