How Price Tracking Works
From real-time API polling to coupon matching, discover how our automated price engine operates.
1. Live API Data Collection
Our distributed crawlers query authorized merchant developer APIs (Amazon Product Advertising API 5.0, Walmart Developer API v2, Best Buy Products API, and Target Partner Feeds) continuously. This ensures prices reflect real-time Buy Box numbers, not cached stale figures.
2. Algorithmic Price Normalization
Every product listing across different merchants has unique identifiers (ASIN, TCIN, SKU). Our normalization engine maps these items into unified product models, comparing identical technical specs, memory, storage, and models.
3. Mathematical Savings Benchmark
We calculate true savings by comparing the current lowest in-stock offer against legitimate retailer regular prices. Fake markup discounts are automatically filtered out.
4. Direct Affiliate Go Routing
When you choose a retailer, our secure routing system sends you directly to the merchant's checkout page with applicable coupons and verified availability.
