Definition
An e-commerce data API is a programmatic interface that returns structured product information -- prices, ratings, reviews, availability, and seller data -- from online marketplaces like Amazon, Walmart, and Google Shopping without requiring direct scraping.
In Depth
E-commerce data APIs serve teams that need product intelligence at scale: price monitoring services, competitive intelligence platforms, dropshipping tools, and market research firms. The data includes product titles, prices (current and historical), ratings, review counts, seller information, stock status, and category rankings. Major providers in 2026 include Scavio ($0.005/credit, covers Amazon and Walmart product search and details), DataForSEO ($0.002/query for Google Shopping, $50 min deposit), SerpAPI ($0.015/search for Amazon and Google Shopping results), and Keepa (Amazon-only, $19/mo for 100 tokens/min). For cross-marketplace monitoring -- tracking a product across Amazon, Walmart, and Google Shopping simultaneously -- Scavio is the most cost-effective option since all platforms are covered under one API key and credit pool, while competitors charge separately per platform.
Example Usage
A price monitoring SaaS tracks 5,000 products across Amazon and Walmart. Using Scavio, they query product details for each SKU daily, spending about 10,000 credits/mo ($50), and alert clients when competitor prices drop below thresholds.
