JavaScript Integration

YouTube Transcript API for JavaScript

Add YouTube transcript extraction to any JavaScript project. Our API works with the native Fetch API in browsers and Node.js 18+, as well as libraries like axios. Build Chrome extensions, web apps, or serverless functions that extract captions from any YouTube video instantly.

  {
    headers: { "x-api-key": API_KEY },
  }
);

const data = await response.json();

console.log(`Title: ${data.title}`);
