How this service works
Barcode validator: EAN-8, UPC-A, EAN-13 and GTIN-14 check digits. Input: barcode digits.
Output
A JSON object containing the submitted barcode code, its detected type (EAN-8, UPC-A, EAN-13, or GTIN-14), a boolean validity flag, the GS1 prefix, the actual check digit from the input, and the expected check digit — so you can immediately see whether the barcode is correct and why.
Example use cases
E-commerce product listing validation
“Before I add this product to my store, can you validate the barcode 012345678905 to make sure the UPC-A check digit is correct?”
Retail inventory data cleanup
“I have a batch of EAN-13 codes from my supplier — can you start by checking whether 5901234123457 is a valid barcode?”
Label printing preflight check
“I'm about to print product labels with GTIN-14 code 10012345678902 — can you verify it's a valid barcode before I send it to the printer?”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/barcode-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call barcode check digit validator without integrating a full GS1 or product database. Ideal for agents doing data quality checks on product codes before listing, printing, or ingesting into a catalog, especially when you only need format/check-digit validity rather than product lookup.
Side effects
- Non-numeric input returns an error
- Barcode length not matching any supported format (not 8, 12, 13, or 14 digits) returns an error
- Missing input field causes a validation error
- Transient server unavailability on Render.com free tier may cause cold-start delays or 502 errors
