What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

• view_invoice_demo

  Demonstrate the engine on bundled synthetic samples only; never checks a user's invoice. Use for product evaluation without a key. To check a supplied document, choose validate_invoice. Choose sample=valid to inspect a passing CII invoice or sample=invalid to see the missing-buye

• generate_invoice

  Create an EN 16931 e-invoice from structured data: Factur-X PDF/A-3, CII XML, or UBL 2.1 XML. Use when you have the parties, lines and dates and need the document. To revise one, correct the input and regenerate; save and deliver the returned file through your own system. Do not

• embed_xml

  Combine a visual PDF you already have with CII XML into one Factur-X PDF/A-3. Use for an existing visual invoice; use generate_invoice to render invoice data or produce UBL. Match the PDF's parties, lines and totals to xml yourself: check examines only XML and cannot detect disag

• validate_invoice

  Check a Factur-X PDF, CII XML or UBL XML against EN 16931, and report the fields to fix. Use when the caller supplies a document, including after corrections; use extract_invoice for business data. With no document and only a request to try the product, choose view_invoice_demo i

• extract_invoice

  Extract invoice parties, dates, lines, totals and VAT as JSON for bookkeeping or matching. Use validate_invoice for compliance; this performs no OCR or recalculation. Supply one source: nonblank xml overrides document_base64 without inspecting it, so omit xml to extract a PDF's a

• check_party

  Check exactly one seller or buyer's registry identifiers and readiness through EU Verify. Use to correct one party's identifiers; use check_invoice_parties to check seller and buyer together, or validate_invoice for document rules. Supply siren, siret or vat; siret wins over sire

• check_invoice_parties

  Check a supplied seller AND buyer together, returning combined readiness and separate evidence. Use before generate_invoice; use check_party for one party and validate_invoice for document rules. Each party needs siren, siret or vat; siret wins over siren. French identifiers or c

• explain_finding

  Turn a validation rule id into the invoice field to change and an example value. Use after validate_invoice or a generate_invoice rule error, not to validate an invoice itself. rule is trimmed and uppercased to select a guide entry. message/json_pointer must come from that same f

• get_invoice_example

  Return a complete invoice or credit-note example to edit and pass to generate_invoice. Use this first, instead of inventing fields. No API key is required, and the call does not count as a document. The seller and buyer are sample data: replace them, the number, the dates and the

• draft_credit_note

  Draft a type-381 credit note from an existing invoice, for all lines or selected quantities. Use to reverse an existing invoice's charges; use get_invoice_example for a synthetic credit-note example. invoice must be the original generate_invoice input object, not extract_invoice
