About ProductGuru

ProductGuru is a free, open barcode and product database built for developers, businesses, price-comparison engines, e-commerce platforms, and curious consumers. We aggregate product data from dozens of public sources and give every product in our database a CertaScore — a data confidence rating that tells you how reliable each record is.

What We Do

• Barcode lookup: Scan or type any EAN-8 or EAN-13 barcode to get the product name, brand, manufacturer, category, country of origin, and more — instantly, for free.
• Product search: Find products by name or keyword across 46 million records.
• Free API: Our REST API requires no API key and no registration. Developers can query the /lookup/{ean}.json and /search?q= endpoints directly.
• Brand Portal: Brands and manufacturers can claim their products and correct their factual attributes to improve data quality.

CertaScore — Data Confidence Rating

Every product record in ProductGuru carries a CertaScore (0–100%), our proprietary measure of how confident we are in the accuracy of the product data.

• 70–100% — High confidence. Data corroborated across multiple authoritative sources. Still verify anything you act on against the manufacturer or the relevant register.
• 40–69% — Medium confidence. Data exists but may have gaps or minor inconsistencies.
• 0–39% — Low confidence. Limited data available; the EAN is valid but product details may be incomplete or unverified.

CertaScore is recalculated automatically as new data is ingested. Brands can improve their product's score by submitting verified data through the Brand Portal.

Data Sources & Methodology

Our database is aggregated from public, authoritative sources. Every record undergoes EAN checksum validation and cross-source deduplication before it enters the database. Full data sources breakdown →

• USDA Branded Foods — 1.3M+ U.S. food products, official government data
• Open Food Facts / Open Beauty Facts / Open Pet Food Facts — global community-curated database (ODbL licence)
• GLEIF / EU Manufacturers — legal entity and manufacturer registry
• MusicBrainz — 1.5M+ music product barcodes (CC0)
• GS1 / Web Data Commons — structured product data extracted from the public web

AI-generated product descriptions and attributes are labelled "AI-estimated" on /p/<ean> product pages. Each page carries a visible provenance chip linking to how we use AI: "Generated automatically from a template" where a program assembled the page from stored data, "AI-generated" where AI drafted it (individual pages are not reviewed before publication), and "Compiled from an official source" on recall and register pages, which contain no AI-generated text. All AI output is synthesised from public product information and does not reproduce copyrighted content.

Free API for Developers

The ProductGuru API is free, requires no authentication, and returns JSON:

• GET /lookup/{ean}.json — Look up a single product by EAN barcode
• GET /search?q={query} — Search by product name or EAN
• GET /catalog/stats — Database statistics
