Shopify Price Drop & Catalog Delta Tracker (Save 85%)

🛑 Stop wasting money on full catalog dumps and slow headless browsers. Traditional Shopify scrapers extract 10,000 unchanged items every single day, burning through your proxy budget and overwhelming your webhook pipelines with repetitive data.
⚡ The Smart Delta Solution: Shopify Price Drop & Catalog Delta Tracker connects directly to public JSON feeds with Zero-Browser architecture (executing in 2–3 seconds), stores catalog snapshots in persistent memory, and alerts you ONLY when prices drop, products restock, or new items launch — saving over 85% on compute and data transfer. Ready for AI agents, repricers, and Zapier/Slack webhooks.

⚡ Why Choose This Actor?

API-First & Zero-Browser: Queries Shopify's public /products.json directly. Zero heavy headless browsers, zero rendering latency, 99% less bandwidth. Runs in under 3 seconds.
Smart Delta Memory: Uses persistent Key-Value storage to track historical snapshots. On each run, it calculates exact mathematical deltas.
Pay-Per-Event (PPE) Micro-Monetization: Quiet runs where nothing changed cost you $0 in event fees. You only pay when actionable events are detected.
AI Agent & Webhook Ready: Feeds clean JSON directly into Slack, Discord, Email, or internal repricing bots without needing duplicate filters.
