🚀 Quick Start

1. Try with the prefill data

The input already has 3 Amazon ASINs pre-filled. Click "Run" and get back price snapshots in seconds.

2. Add your own products

Replace the prefill with your ASINs or product URLs. Auto-detection handles any platform.

3. Enable scheduling

Set a daily schedule in Apify Console. Each run appends to the price history automatically.

4. Get alerts

Check the alerts array in each output record. Price drops, stock changes, and competitor alerts are computed every run.

5. Integrate via API

curl -X POST "https://api.apify.com/v2/acts/luckborn~multi-platform-price-intelligence/runs" \
  -H "Content-Type: application/json" \
  -d '{
    "asins": ["B08N5WRWNW", "B0B7X9X1Y2"],
    "priceDropThresholdPercent": 10
  }'

🧠 Tips

1. Run daily, not hourly — prices change daily. Hourly runs waste money and increase blocking risk.
2. Start small — test with 10 ASINs first. Validate output format, then scale to hundreds.
3. Set a realistic alert threshold — 5% is good for electronics, 10%+ for consumables. Too low = noise.
4. Use the competitorPrices input — provide known competitor prices manually for cross-platform alerts.
5. Check priceStats.trend — "down" means this product is in a price war. "up" means supply constraints.

🔒 Privacy & Compliance

• No login required — all scraping is from public product pages
• No customer data — only product pricing data is extracted
• Compliant with standard web scraping practices for publicly listed prices
• Rate-limited by design — we don't hammer any single domain

---

🐛 Known Limitations

• Walmart uses JS-rendered prices — Playwright is slower and may fail with aggressive anti-bot on high-volume runs
• Shopify stores vary in template structure — standard Liquid stores work reliably; custom templates may return partial data
• Price history is only as good as your run frequency — daily runs give 90-day windows
• Competitor prices require manual input in MVP — full auto-discovery coming in v1.1

---
