How this service works
Validate UPC/EAN/GTIN checksum offline, then look up the barcode on Open Food Facts when it is a food/consumer item. Non-food codes often checksum-ok with no product match.
Output
Returns whether the barcode checksum is valid (offline check), and if the code matches a food/consumer item, returns product details from Open Food Facts such as product name, category, and other available metadata. Non-food barcodes may pass checksum validation but return no product match.
Example use cases
Grocery item identification from scan
“I scanned the barcode 0737628064502 from a item in my pantry — can you tell me what product this is and confirm the barcode is valid?”
E-commerce listing validation
“I have a list of UPC codes for products I'm listing online — can you check if 012000030888 is a valid barcode and what product it corresponds to?”
Food label verification
“Can you verify that the EAN code 4006381333931 has a valid checksum and look up whether there's a matching food product in the database?”

Endpoint
GEThttps://402.com.tr/api/x402/upc-lookupWhen to prefer
Use this endpoint when you need to identify a consumer product from its UPC, EAN, or GTIN barcode — especially for food items where Open Food Facts coverage is strong. It is a cost-effective single-call solution combining offline checksum validation with a live product lookup, making it ideal for lightweight product identification without needing a paid barcode database subscription.
Side effects
- Valid checksum but no product found (common for non-food/industrial barcodes)
- Invalid barcode digits fail checksum validation immediately
- Malformed or non-numeric input rejected
- Product exists but Open Food Facts has no data for it
- Network timeout on Open Food Facts lookup
