Product data APIs fall into a few kinds: barcode databases that return product details, marketplace APIs that go deep on one store, multi-retailer price APIs, dataset vendors, and search-results scrapers. Which one fits depends on what you send (a barcode, an ASIN, a URL, a keyword) and what you need back (details, today's prices, or history). This page lays the main options side by side with what each vendor publishes, checked on the date shown.

A barcode API turns a code into product details (name, brand, images, attributes). A price API returns current offers (retailer, price, availability) for a product, and the better ones keep history. Some barcode APIs add a snapshot of store prices; ShopSavvy returns the product record plus timestamped offers and history.
UPCitemdb has a free tier (100 requests a day, no signup). The ShopSavvy Data API has no free tier but a 14-day Starter trial, and the ShopSavvy MCP server is free without a key for AI assistants.
For Amazon alone, Keepa. Across retailers, ShopSavvy keeps hundreds of millions of price observations with price history back to 2011, dense from 2019. Barcode databases generally do not offer dated history.
Each vendor's facts come from its public pages, read on the dates below; where its own page could not be read we cite a third-party listing. The list covers options we have checked and is not exhaustive. We make ShopSavvy, so weigh our entry accordingly. Corrections: business@shopsavvy.com.
