How this service works
Call when an agent has an 8 or 13 digit barcode and needs the checksum result and the GS1 prefix country. Does not confirm the product or a price.
Output
Returns whether the EAN-8 or EAN-13 checksum is valid and identifies the GS1 country associated with the barcode's prefix. Does not look up or confirm any specific product or price.
Example use cases
Barcode integrity check before catalog import
“I'm about to import a product catalog and one of the barcodes is 73513537. Can you check if the checksum on that EAN-8 is valid and what GS1 country it belongs to?”
E-commerce listing country origin check
“We scanned a product barcode of 4006381333931 — can you verify the EAN-13 checksum is correct and tell me what country the GS1 prefix points to?”
Inventory data quality audit
“Our warehouse system flagged barcode 0012345678905 as potentially invalid — can you check the checksum and let me know if it passes and what the GS1 country prefix is?”
Technical details
Endpoint
GEThttps://agentshield.live/ean?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a raw EAN-8 or EAN-13 barcode string and need to verify its check digit mathematically and identify the GS1 issuing country. It is not a product database lookup — prefer it for data validation, catalog hygiene, and supply chain integrity checks rather than price or product detail retrieval.
Side effects
- Missing or empty 'code' query parameter returns an error
- Non-numeric characters in barcode cause validation failure
- Barcode length other than 8 or 13 digits returns an error
- Invalid or unrecognized GS1 prefix may return unknown country
