Validate UPC-A, EAN-13, EAN-8, or GTIN-14 check digit

Validates any GS1 retail barcode: UPC-A (12), EAN-13 (13), EAN-8 (8), or GTIN-14 (14). Uses the shared alternating-weight mod-10 algorithm. Returns the form label, length, check digit, and the code left-padded to GTIN-14 for uniform storage.

Query parameters

include_receiptboolean

Set true to attach an execution receipt at meta.receipt — caller-verifiable sha256 hashes over the RFC 8785 (JCS) canonicalization of this call's as-received JSON body and its result (free, like include_trace). Reproduce with any JCS library: input_hash = sha256(jcs({"tool": <request path>, "args": <your body minus include_trace/include_receipt>})); result_hash = sha256(jcs(result)). For deterministic tools, same input on the same build reproduces result_hash.
