Current tools (5)

validate_xmlValidate an XML document with xmlvalid: well-formedness, an XSD, DTD or RelaxNG schema, and for e-invoices the Schematron business rules of EN 16931, Peppol BIS, XRechnung, Factur-X and national formats. Pass the document as `xml` (its text) or `url` (a public http(s) address), and a `schema`: a catalog slug from search_schemas, a saved schema ("@orders-v3"), or "auto" to use the e-invoice profile
params: xml, url, schema, name, rules_version, wait
get_validationThe status and result of a validation started with validate_xml that was still running when it returned (status "queued" or "running"). Results are kept for 24 hours.
params: id*
search_schemasSearch xmlvalid's catalog of official XML schemas (UBL, CII, Peppol, XRechnung, Factur-X, ISO 20022, HL7, sitemaps…) by name, namespace, root element or area. Returns each schema's slug to pass to validate_xml, its version and the business rules it checks. No API key needed.
params: query
explain_errorExplain an XML parsing or schema validation error message: what it means, why it happens and how to fix it, with an example. Understands libxml2 (xmllint, PHP, Python lxml, xmlvalid), Java (Xerces cvc-* codes, SAXParseException) and .NET (System.Xml) wording; paste the message as reported, stack trace prefix included. No API key needed.
params: message*
explain_ruleExplain an e-invoicing business rule by its id, such as BR-CO-15, BR-DE-1, PEPPOL-EN16931-R001 or a national CIUS rule: its message, level, the rule sets it belongs to, why invoices fail it and how to fix them. No API key needed.
params: id*
