Server instructions

InvoiceIn reads the e-invoices a business receives. Five read-only tools, each taking one invoice file (XML in UBL, CII, XRechnung, Peppol BIS 3, FatturaPA or KSeF syntax, or a ZUGFeRD/Factur-X hybrid PDF) base64-encoded in `file_base64`, up to 25 MB: read_invoice (data + validation), validate_invoice (verdict only), invoice_to_html (printable view), invoice_to_csv (flat table), invoice_to_datev (German bookkeeping import). Every tool call costs one invoice credit; without an API key the anonymous quota is 20 invoices per day per IP. Files are processed in memory and never stored.

Known tools 5

read_invoice

Parse one European e-invoice into canonical EN 16931 JSON and validate it against the official rule sets in the same call.

Potential side effects

validate_invoice

Validate one European e-invoice against the official rule sets (XSD, EN 16931, XRechnung, Peppol BIS, FatturaPA, KSeF, arithmetic) and return the verdict without the invoice body.

Potential side effects

invoice_to_html

Render one European e-invoice as a self-contained, printable HTML page: header, seller and buyer, line items, VAT breakdown, totals and payment details in one layout regardless of the source syntax, labels in `lang`.

Potential side effects

invoice_to_csv

Export one European e-invoice as a flat CSV table for a spreadsheet or a database import.

Potential side effects

invoice_to_datev

Convert one received (purchase) e-invoice into a DATEV Buchungsstapel import file (EXTF format 700) for German bookkeeping in DATEV Kanzlei-Rechnungswesen or Unternehmen online.
