Use formats filter to restrict results. |
| render_barcode | Render text as a barcode PNG. format: one of qr, aztec, datamatrix, code128, code39, code93, ean13, ean8, upca, itf, pdf417. Output: base64 PNG plus 'decoded' self-check flag (we decode our own render; upca intentionally verifies as zero-padded EAN-13). GTIN codes must have a valid mod-10 checksum. |
| validate_gtin | Check a product code against GTIN rules: length + mod-10 checksum. Returns {valid, type: ean13|ean8|upcA|null, normalized}. Rejects codes with a broken checksum (e.g. 8595234703191). |
