Common Use Cases

1. Extract Audio from YouTube Videos

Perfect for podcast tools, music apps, or audio analysis:

async function extractAudio(videoUrl, accessKey, audioFormat = 'mp3') {
  const data = await downloadYouTubeVideo(videoUrl, accessKey, audioFormat);

  console.log(`Audio extracted: ${data.data.title}`);
  console.log(`Format: ${data.data.format}`);
  console.log(`Size: ${data.data.fileSizeMB}`);
  console.log(`Download: ${data.data.downloadUrl}`);

  return data.data.downloadUrl;
}

// Extract MP3 audio
extractAudio('https://www.youtube.com/watch?v=VIDEO_ID', 'your-access-key', 'mp3');

2. Batch Download Multiple Videos

Download a list of videos in bulk:

async function batchDownload(videoUrls, accessKey, format = 'mp4', quality = '360p') {
  const results = [];

  for (const url of videoUrls) {
    try {
      const data = await downloadYouTubeVideo(url, accessKey, format, quality);
      results.push({
        url,
        title: data.data.title,
        downloadUrl: data.data.downloadUrl,
        size: data.data.fileSizeMB,
        status: 'success'
      });
      console.log(`Downloaded: ${data.data.title} (${data.data.fileSizeMB})`);
    } catch (error) {
      results.push({ url, status: 'failed', error: error.message });
      console.error(`Failed: ${url} - ${error.message}`);
    }
  }

  return results;
}

// Usage
const videos = [
  'https://www.youtube.com/watch?v=VIDEO_1',
  'https://www.youtube.com/watch?v=VIDEO_2',
  'https://www.youtube.com/watch?v=VIDEO_3'
];

batchDownload(videos, 'your-access-key', 'mp4', '720p');

3. Content Repurposing Pipeline

Combine the Download API with other SocialKit APIs for a full repurposing workflow:

async function repurposeVideo(videoUrl, accessKey) {
  // Step 1: Download the video
  const download = await downloadYouTubeVideo(videoUrl, accessKey, 'mp4', '720p');

  // Step 2: Get the transcript
  const transcriptRes = await axios.get('https://api.socialkit.dev/youtube/transcript', {
    params: { access_key: accessKey, url: videoUrl }
  });

  // Step 3: Get an AI summary
  const summaryRes = await axios.get('https://api.socialkit.dev/youtube/summarize', {
    params: { access_key: accessKey, url: videoUrl }
  });

  return {
    videoFile: download.data.downloadUrl,
    transcript: transcriptRes.data.data,
    summary: summaryRes.data.data,
    metadata: {
      title: download.data.title,
      duration: download.data.duration
    }
  };
}

4. Video to Podcast Converter

Convert YouTube videos to audio files for podcast feeds:

async function videoToPodcast(videoUrl, accessKey) {
  const data = await downloadYouTubeVideo(videoUrl, accessKey, 'mp3');

  return {
    title: data.data.title,
    audioUrl: data.data.downloadUrl,
    duration: data.data.durationSeconds,
    format: 'mp3',
    fileSize: data.data.fileSize
  };
}

// Convert multiple videos to podcast episodes
async function createPodcastFeed(videoUrls, accessKey) {
  const episodes = [];

  for (const url of videoUrls) {
    const episode = await videoToPodcast(url, accessKey);
    episodes.push(episode);
    console.log(`Converted: ${episode.title} (${data.data.fileSizeMB})`);
  }

  return episodes;
}

Advanced Features

Download with Automatic Format Selection

Choose the best format based on your use case:

function getOptimalSettings(useCase) {
  switch (useCase) {
    case 'archive':
      return { format: 'mp4', quality: '1080p' };
    case 'mobile':
      return { format: 'mp4', quality: '360p' };
    case 'audio-only':
      return { format: 'mp3', quality: '360p' };
    case 'web-embed':
      return { format: 'webm', quality: '480p' };
    case 'high-quality-audio':
      return { format: 'wav', quality: '360p' };
    default:
      return { format: 'mp4', quality: '720p' };
  }
}

async function smartDownload(videoUrl, accessKey, useCase) {
  const { format, quality } = getOptimalSettings(useCase);
  return downloadYouTubeVideo(videoUrl, accessKey, format, quality);
}

// Usage
smartDownload('https://www.youtube.com/watch?v=VIDEO_ID', 'your-access-key', 'audio-only');

Download and Upload to Your Own Storage

Pipe the download directly to your own S3 bucket or cloud storage:

const { S3Client, PutObjectCommand } = require('@aws-sdk/client-s3');
const axios = require('axios');

async function downloadToS3(videoUrl, accessKey, bucket, s3Key) {
  // Get download URL from SocialKit
  const result = await downloadYouTubeVideo(videoUrl, accessKey, 'mp4', '720p');
  const downloadUrl = result.data.downloadUrl;

  // Download the file
  const fileResponse = await axios.get(downloadUrl, { responseType: 'arraybuffer' });

  // Upload to your S3
  const s3 = new S3Client({ region: 'us-east-1' });
  await s3.send(new PutObjectCommand({
    Bucket: bucket,
    Key: s3Key,
    Body: fileResponse.data,
    ContentType: 'video/mp4'
  }));

  console.log(`Uploaded to s3://${bucket}/${s3Key}`);
}

Export Download Results to CSV

const fs = require('fs');

async function exportDownloadsToCSV(videoUrls, accessKey, filename) {
  const results = await batchDownload(videoUrls, accessKey);

  const csv = [
    ['Title', 'URL', 'Format', 'Size', 'Download URL', 'Status'].join(','),
    ...results.map(r => [
      `"${r.title || ''}"`,
      r.url,
      r.format || 'mp4',
      r.size || '',
      r.downloadUrl || '',
      r.status
    ].join(','))
  ].join('\n');

  fs.writeFileSync(filename, csv);
  console.log(`Exported ${results.length} downloads to ${filename}`);
}

Frequently Asked Questions

What's the maximum file size?

Downloads are limited to 10MB per file. For longer or higher-quality videos, try a lower quality setting (240p or 360p) or use an audio-only format (MP3, M4A) which produces much smaller files.

How long do download URLs last?

Download URLs are valid for 1 hour. After that, you'll need to make a new API request to get a fresh URL.

What YouTube URL formats are supported?

The API accepts various YouTube URL formats:

• https://www.youtube.com/watch?v=VIDEO_ID
• https://youtu.be/VIDEO_ID
• https://www.youtube.com/embed/VIDEO_ID
• https://www.youtube.com/shorts/VIDEO_ID

Can I download private or age-restricted videos?

No, the API only works with publicly available YouTube videos. Private, unlisted, or age-restricted videos cannot be downloaded.

Which format should I choose?

• MP4 - Best all-around choice for video. Works on every device and platform.
• MP3 - Best for audio extraction. Smallest audio file size.
• M4A - Better audio quality than MP3 at the same bitrate.
• WebM - Best for web embedding with HTML5 video players.
• WAV - Best for audio processing and editing (uncompressed).

Are there rate limits?

Yes, rate limits depend on your subscription plan. Implement appropriate delays between requests for batch downloads.

Why Use an API Instead of Self-Hosting yt-dlp?

Running your own yt-dlp server is possible, but comes with real challenges:

Challenges of Self-Hosting:

❌ Binary Updates - yt-dlp breaks regularly when YouTube changes their systems ❌ FFmpeg Required - Format conversion needs FFmpeg installed and configured ❌ Storage Management - You need S3 or similar storage for serving files ❌ Bandwidth Costs - Downloading and re-uploading videos uses significant bandwidth ❌ Server Resources - Video processing is CPU and memory intensive ❌ Maintenance Burden - Monitoring, updating, and fixing breakage is ongoing work

Benefits of the API:

✅ Zero Maintenance - We handle yt-dlp updates and YouTube changes ✅ No Infrastructure - No servers, storage, or FFmpeg to manage ✅ Built-in Conversion - 7 formats supported without any setup ✅ Pre-signed URLs - Files served directly from S3, no bandwidth on your end ✅ Simple Integration - One POST request replaces hundreds of lines of code ✅ Cost Effective - Pay per download, no fixed infrastructure costs

Pricing
