Generate A Guaranteed En 16931 Conformant E Invoice API

Generate a guaranteed EN 16931-conformant e-invoice: post simple business JSON (parties, lines, VAT) and get XML that has already passed the full official rule set - totals computed for you, inconsistent inputs rejected with actionable field-level errors. Default output is CII (Factur-X EN 16931 profile URN); set syntax=ubl for a UBL 2.1 invoice, and add ruleset=peppol for a guaranteed-conformant Peppol BIS Billing 3.0 document (Belgium mandate, live since 2026-04). Ready for the French 2026-2027 reform. No account, no key.
