Using the Post Info API

const response = await fetch(
  'https://api.sociavault.com/v1/scrape/instagram/post-info?url=https://www.instagram.com/p/DMA4eb1RC0D/',
  {
    method: 'GET',
    headers: {
      'x-api-key': 'YOUR_API_KEY'
    }
  }
);

const result = await response.json();
const post = result.data.data.xdt_shortcode_media;

You can also pass trim=true to get a smaller response.

Use Cases

Engagement Analysis

Calculate engagement rate for specific posts:

async function getPostInfo(url) {
  const res = await fetch(
    `https://api.sociavault.com/v1/scrape/instagram/post-info?url=${encodeURIComponent(url)}`,
    { headers: { 'x-api-key': 'YOUR_API_KEY' } }
  );
  return res.json();
}

const result = await getPostInfo('https://www.instagram.com/p/DMA4eb1RC0D/');
const post = result.data.data.xdt_shortcode_media;

const likes = post.edge_media_preview_like.count;
const comments = post.edge_media_to_parent_comment.count;
const followers = post.owner.edge_followed_by.count;

const engagementRate = ((likes + comments) / followers) * 100;
console.log(`Engagement rate: ${engagementRate.toFixed(2)}%`);

Track Viral Content

Monitor post performance over time:

async function trackPost(url) {
  const result = await getPostInfo(url);
  const post = result.data.data.xdt_shortcode_media;
  
  await saveSnapshot({
    postId: post.id,
    likes: post.edge_media_preview_like.count,
    comments: post.edge_media_to_parent_comment.count,
    views: post.video_play_count || 0,
    timestamp: new Date()
  });
}

// Track every hour
setInterval(() => trackPost(targetUrl), 60 * 60 * 1000);

Extract Media URLs

Download post images/videos:

const result = await getPostInfo(url);
const post = result.data.data.xdt_shortcode_media;

if (post.is_video) {
  console.log('Video URL:', post.video_url);
  console.log('Duration:', post.video_duration, 'seconds');
  console.log('Plays:', post.video_play_count);
} else {
  console.log('Image URL:', post.display_url);
  console.log('Dimensions:', post.dimensions);
}

Reel Audio Analysis

Check audio details for reels:

const result = await getPostInfo(reelUrl);
const post = result.data.data.xdt_shortcode_media;

if (post.clips_music_attribution_info) {
  const audio = post.clips_music_attribution_info;
  console.log(`Audio: "${audio.song_name}" by ${audio.artist_name}`);
  console.log(`Original audio: ${audio.uses_original_audio}`);
}

Frequently Asked Questions

Can I use the post shortcode instead of URL?

What's the difference between views and plays for Reels?

Views typically count unique viewers, while plays count total playbacks (including repeats).

Can I get data from private account posts?

No, only publicly accessible posts can be scraped. Private accounts restrict access.

Are Instagram Stories supported?

No, Stories are temporary and handled differently. Use the Highlights endpoint for saved story content.

How do I get carousel images in order?

The media array is returned in the order displayed in the carousel, from first to last slide.
