Finding Audio IDs

To use this endpoint, you need an audio ID. Here's how to get it:

From a Reel URL

Extract the audio ID from any Reel using a specific sound:

// Get Reel info first
const reelInfo = await fetch('https://api.sociavault.com/instagram/post-info', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    url: 'https://www.instagram.com/reel/ABC123xyz/'
  })
});

const { audio } = await reelInfo.json();
const audioId = audio.id; // Use this for reels-by-song

Use Cases

Brand UGC Discovery

Find content using your brand's audio:

const brandAudioId = 'your-brand-audio-id';

async function findBrandUGC() {
  const { reels } = await getReelsByAudio(brandAudioId);
  
  // Filter by quality
  const qualityUGC = reels.filter(r => 
    r.views > 10000 && 
    r.author.followers > 1000
  );
  
  return qualityUGC;
}

Track Sound Virality

Monitor how fast a sound is spreading:

async function trackSoundGrowth(audioId) {
  const data = await getReelsByAudio(audioId);
  
  await saveMetric({
    audioId,
    totalUsage: data.usageCount,
    timestamp: new Date()
  });
  
  // Calculate daily growth
  const yesterday = await getYesterdayMetric(audioId);
  const growth = data.usageCount - yesterday.totalUsage;
  
  console.log(`Sound grew by ${growth.toLocaleString()} uses in 24h`);
}

Find Influencers Using Sounds

Discover creators engaging with specific audio:

async function findCreatorsUsingSound(audioId) {
  const { reels } = await getReelsByAudio(audioId);
  
  // Get unique creators with high engagement
  const creators = [...new Map(
    reels.map(r => [r.author.username, r.author])
  ).values()];
  
  // Filter for influencers
  const influencers = creators.filter(c => c.followers >= 10000);
  
  return influencers;
}

Compare Sound Performance

Analyze which sounds drive better engagement:

async function compareSounds(audioIds) {
  const results = await Promise.all(
    audioIds.map(async id => {
      const { reels, usageCount, audioTitle } = await getReelsByAudio(id);
      
      const avgViews = reels.reduce((s, r) => s + r.views, 0) / reels.length;
      const avgLikes = reels.reduce((s, r) => s + r.likes, 0) / reels.length;
      
      return {
        audioId: id,
        title: audioTitle,
        totalUses: usageCount,
        avgViews,
        avgLikes,
        engagementRate: avgLikes / avgViews
      };
    })
  );
  
  return results.sort((a, b) => b.engagementRate - a.engagementRate);
}
