Romanian e-Factura & Peppol Invoice XML Validator

API ↗

Romanian e-Factura & Peppol Invoice XML Validator is a paid API for AI agents from einvoice.alexhub.uk, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Validates a UBL 2.1 XML invoice against Romanian CIUS-RO, Peppol BIS Billing 3.0, or EN 16931 rules and returns detailed, actionable error explanations with correct field paths and computed fix values.

How this service works

Check a Romanian e-Factura (UBL 2.1, CIUS-RO 1.0.9) before uploading it to ANAF SPV, and get the exact fix for every error: plain-English explanation, the official Romanian rule text, the UBL path of the field and, for amount errors, the correct value computed from the invoice (chained, so following the report gives a consistent invoice). Also validates Peppol BIS Billing 3.0 and EN 16931. No account: $0.01 per invoice via x402, plus a small free tier.

Output

A structured report listing every validation error found in the invoice XML, each with a plain-English explanation, the official Romanian or Peppol rule text, the UBL XPath of the offending field, and for amount/calculation errors, the correctly computed value derived from the invoice data — errors are chained so fixing them in order produces a consistent invoice. A passing invoice returns a clean compliance confirmation.
