Product Data API
Structured JSON product intelligence — identifiers, catalog, Amazon ASIN mapping, and bulk batch lookup.
Free daily lookups · UPC, EAN, GTIN, ISBN & ASIN · 1.6B+ products
A **product data API** returns everything your app needs from a single barcode or ASIN: title, brand, category, images, dimensions, sales rank, and cross-marketplace identifiers. EcomSource is built for developers who outgrew scraping and need reliable **product data api** access at scale.
What you get from the product data API
Each response can include UPC, EAN, GTIN, ASIN, variation trees, hazmat flags, and pricing signals. One endpoint accepts mixed identifier types — ideal for catalog enrichment, arbitrage tools, and warehouse systems.
Product data API vs Amazon SP-API alone
SP-API is marketplace-specific and heavy to integrate. EcomSource product data API focuses on fast identifier resolution and normalized JSON — often used alongside SP-API for cross-reference and bulk preprocessing.
