ean_gtin
shallowcom.temsor/api · Verify this server
Validates GTIN-8, UPC-A (12), EAN-13 and GTIN-14 check digits for retail barcodes. Retail GTINs share one GS1 check-digit algorithm with length-dependent packing (8 / 12 / 13 / 14). This endpoint stays on that retail identity: it does not guess shipping carriers. For 13-digit codes the leading three digits are returned as a GS1 company-prefix hint; 868/869 mark Türkiye. A matching check digit is arithmetic consistency, not proof the SKU is listed in a brand catalogue.
