How this service works
Validate EAN-8, EAN-13, UPC-A, GTIN-14, ISBN-10 and ISBN-13: check digit (and the expected one if wrong), code type, GS1 prefix and registering country, plus ISBN-10/13 conversion.
Output
Returns a JSON object with: the normalized barcode string, a boolean validity flag, the barcode type (e.g. EAN-13, ISBN-13), the GS1 prefix code, the GS1 record (country of registration), the control digit, and an explanatory note about GS1 prefix semantics.
Example use cases
Product listing barcode verification
“I'm about to list a product on our e-commerce platform with barcode 0614141999996 — can you check if it's a valid barcode and tell me its type and GS1 country registration?”
ISBN validation before book cataloguing
“Before I add this book to our library system, can you validate the ISBN 978-3-16-148410-0 and confirm it's a legitimate code?”
Suspicious barcode audit
“We received some products with barcode 5901234123457 and I'm not sure if it's genuine — can you validate it and tell me what country it's registered to and whether the check digit is correct?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/barcode-validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically validate barcodes or ISBNs, identify their format type, and look up the GS1 country of registration — especially useful in e-commerce, logistics, or library cataloguing workflows where barcode integrity must be confirmed before downstream processing.
Side effects
- Invalid or malformed barcode digits returns valid: false with no GS1 data
- Unsupported barcode format may return null type field
- Non-numeric input or input with invalid characters may fail schema validation
- Missing required 'code' field in request body causes a 400-level error
