• check_invoice_partiesCheck seller and buyer togetherread-only

  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 country_code=FR require SIREN/SIRET; a French lookup can derive omitted vat. Address fields activate address checks. requester_vat applies to both lookups but cannot replace either party's vat. Roles follow seller/buyer argument names; no invoice lines or full invoice body is needed. Makes at m…

• check_partyCheck one invoice partyread-only

  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 siren. A SIREN/SIRET, country_code=FR or FR VAT triggers French checks requiring a SIREN/SIRET. Omitted vat can be derived from a successful French lookup; foreign parties normally need explicit VAT. Send address fields with a coherent country_code; requester_vat cannot substitute for the checked p…

• draft_credit_noteDraft a full or partial credit noteread-only

  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 output. number and issue_date belong to the new credit note; the original number/date are copied into preceding_invoices. Give number a distinct value and use YYYY-MM-DD dates. due_date replaces the original deadline; omitting it removes that deadline rather than inheriting it. Omit credit_lin…

• embed_xmlEmbed CII XML into a PDFread-only

  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 disagreement with the visible PDF. The embedded profile comes from xml; neither check nor language changes it. language does not translate the PDF. Invalid input or failed rules return a tool error with no file; rule errors include ids. For a findings report use validate_invoice. Success returns a …

• explain_findingExplain a validation findingread-only

  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 finding: nonempty values override its generic context, but never change the selected fix or example. Omit them to use guide defaults for known rules. Returns rule, known, message, json_pointer, fix and example; known rules also include problem. Selected BR-FR rules and BR-CO-17/BR-CO-26 have gu…

• extract_invoiceExtract e-invoice dataread-only

  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 attachment. include_xml returns that selected source for archiving or validation, not XML reconstructed from fields. Extracted fields need mapping before use as generate_invoice input. Returns fields and format/profile metadata, plus PDF metadata for PDF input. Missing business values remain nu…

• generate_invoiceGenerate an EN 16931 invoiceread-only

  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 use when you already have a visual PDF and CII XML: call embed_xml. To check a document you did not create here, call validate_invoice; to read one, call extract_invoice. Start invoice from get_invoice_example, replacing sample parties and dates. Leave totals and line net_amount omitted to com…

• get_invoice_exampleGet an invoice or credit-note exampleread-only

  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 lines before you generate. For credit_note, also replace preceding_invoices with the original invoice reference. To credit a real invoice already in hand, use draft_credit_note instead of this synthetic example. Amounts are positive decimal strings. Nothing is stored, and no file is created. R…

• validate_invoiceValidate your invoice documentread-only

  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 instead. Supply one source: nonblank xml overrides document_base64 without inspecting it. To check a PDF's attachment, omit xml. check adds rules to the detected profile; it cannot change that profile. Use base for non-French invoices to avoid French-field findings. Returns validity and finding…

• view_invoice_demoTry fixed invoice samples (no document input)read-only

  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-buyer-name finding. Both use the production XSD and EN 16931 engine; results may be cached for 24 hours for the same engine version and input. Inspect validated_at and cached; a cache hit is not a fresh run. Call with {} to validate the passing sample, or sample=downloads for PDF/CII/UBL files and the …
