Tools (4)

decode_barcodeDetect and decode all barcodes in an image. Input: base64-encoded image bytes (PNG/JPEG/WebP/anything sharp reads). Output: JSON array of {format, text}. Supports QR, Aztec, DataMatrix, Code128/39/93, EAN-13/8, UPC-A/E, ITF, PDF417, Codabar. Use formats filter to restrict results.
render_barcodeRender 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_gtinCheck 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).
list_formatsStatic table of supported barcode formats with render/decode support and notes.
