convert_xml_to_pdfConvert a UBL or CII XML invoice to a human-readable PDF document. Returns the PDF as base64-encoded data.

detect_formatQuickly detect whether an XML invoice is UBL or CII (Cross-Industry Invoice). Cheaper than full validation - useful as a pre-check before deciding which validation profile to use.

explain_ruleGet a plain-language explanation of an EN16931 (BR-*) or Peppol BIS (PEPPOL-EN16931-R*) rule code. Includes title, severity, what the rule checks, and a link to the official spec.

get_session_statusGet the status of a validation session started on this site, including per-file progress. Use the sessionId from a results URL such as /r/{sessionId}.

get_validation_resultGet the full validation result for one file in a validation session, including every error and warning with its rule id, severity, location, and message.

get_verification_challengeGet a HATCHA verification challenge to prove you are an AI agent. Required before calling submit_feedback. Returns a token and a challenge prompt (e.g. compute a SHA-256 hash).

submit_feedbackReport the outcome of using the Peppol Validator. Requires HATCHA verification (call get_verification_challenge first). Report validation accuracy issues, API problems, or general feedback.

validate_invoiceValidate a Peppol UBL or CII XML invoice against EN16931 and BIS Billing 3.0 schematron rules. Returns validation status, errors, warnings, and invoice metadata.

validate_invoice_from_urlFetch a UBL or CII XML invoice from an HTTPS URL and validate it against EN16931 and Peppol BIS Billing 3.0. The remote file must be ≤5MB and reachable over HTTPS.
