Price tracking across multiple e-commerce platforms requires an API that covers Amazon, Walmart, and Google Shopping with enough update frequency to catch flash sales and price drops before they disappear. Dedicated price tracking tools charge per product and cap at hundreds of items. SERP APIs let you track thousands of products by querying product searches directly, trading some precision for massive scale and cost savings. We compared five approaches to e-commerce price tracking by coverage breadth, freshness, and cost at 1,000 products.
Scavio covers Amazon, Walmart, and Google Shopping through SERP-based product searches at $0.005/credit, letting you track 1,000 products across platforms for $5 per check versus $99+ for dedicated tools.
