Automate Product Page Screenshots for E-commerce

Why E-commerce Companies Use Screenshot APIs

• Competitor price monitoring — Capture competitor product pages daily. Visual evidence of pricing changes that web scrapers might miss (dynamic pricing, images, layout changes).
• MAP compliance — Verify that resellers display the correct Minimum Advertised Price. Screenshot proof for enforcement.
• Marketplace listing audits — Ensure your Amazon, Shopify, or Etsy listings look correct across different regions and devices.
• Visual catalog management — Generate thumbnails of your entire product catalog for internal dashboards and reports.
• A/B test documentation — Capture both variants of product page tests for analysis and records.

Example: Daily Competitor Monitoring

// Monitor competitor product pages daily
const competitors = [
  'https://competitor-a.com/product/widget-pro',
  'https://competitor-b.com/products/widget-premium',
  'https://amazon.com/dp/B09XXXXXX'
];

for (const url of competitors) {
  const res = await fetch('https://grabshot.dev/api/screenshot', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'X-API-Key': process.env.GRABSHOT_KEY
    },
    body: JSON.stringify({
      url,
      width: 1440,
      fullPage: true,
      aiCleanup: true  // Remove cookie banners for clean captures
    })
  });
  
  // Store with timestamp for historical comparison
  const date = new Date().toISOString().split('T')[0];
  const filename = `${date}-${new URL(url).hostname}.png`;
  // Save to S3, local storage, or your monitoring dashboard
}
