GS1 Element String Parser & Validator

Choose this endpoint when you need to rigorously parse and validate GS1 element strings — especially when century disambiguation for date AIs (e.g. expiry, production date) is critical, check digit correctness must be confirmed, or decimal AI values need exact extraction. Prefer this over generic barcode decoders when GS1 AI semantics and standards-compliance validation matter, such as in pharmaceutical traceability, retail receiving, or supply chain automation workflows.

• Element string malformed or unparseable — returns validation error
• Unsupported or unknown application identifier — semantic_valid set to false
• Check digit mismatch — check_digit_valid returns false
• Year century enum value not one of 1900, 2000, or 2100 — schema validation error
• Element string exceeds 2048 character limit — rejected at input validation
• Empty element string — rejected with minLength constraint error
• Claim object provided but contradicts parsed data — mismatch flagged in response
