smithery/normapi/e-invoice

Validate and generate German e-invoices (XRechnung, ZUGFeRD) against the official KoSIT rules. Every business-rule finding comes with a plain-language explanation: what the rule requires, why it fires, how to fix it. - validate_invoice: XRechnung XML (UBL or CII) or a ZUGFeRD/Factur-X PDF. No account needed. - generate_invoice: XRechnung UBL/CII or a ZUGFeRD PDF from invoice data, validated before it is returned. Uses your NormAPI account (sign in via OAuth); 25 invoices a month free. - explain_rule: explains a rule code such as BR-DE-15. Invoices are processed in memory and never stored.
