E-Commerce APIs

APIs for retail and marketplace data. Track products, pricing, offers, and reviews across major online stores to power price comparison, monitoring, and market research.

What is E-Commerce API?

An ecommerce API returns product data from online stores as structured JSON: prices, offers, reviews, ratings, sellers, and best sellers. OpenWeb Ninja's e-commerce APIs cover Amazon, Walmart, eBay, Costco, Wayfair, Google Shopping, and aggregated products from any public source on the web, so you can pull live listings without scraping each site yourself. Use them for price comparison and monitoring, competitor research, and catalog enrichment, with a free tier and simple REST endpoints.
