• POST /v1/validate — 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. (0.01 USDC on Base)

• POST /v1/fix — Automatically repair a Romanian e-Factura / UBL 2.1 invoice and return the corrected XML: county and Bucharest sector codes, country, currency and unit codes, date formats, VAT-id prefixes, decimals, and all totals and VAT amounts recomputed from the lines in dependency order. Every change is listed (field, old, new) and the result is re-validated against the official rules. Charged only when something was fixed. (0.05 USDC on Base)
• POST /v1/saft/validate — Check a Romanian SAF-T file (D406, monthly/quarterly) before filing it with ANAF: the official ANAF validator (DUKIntegrator, run for the reporting period) plus the consistency checks it does not do – balanced journal entries, GL totals, opening + movements = closing for every account, trial balance, partner balances, invoice totals, VAT = base × rate, VAT codes valid for the period (21%/11% from August 2025), RON amount = currency × exchange rate, months 1-12, return type (L/T) matching the period, CUI and IBAN check digits, accounts in the ANAF chart. Every finding has a plain-language fix (RO/EN) and the correct value where it can be computed. Send the XML as the request body (up to 100 MB). Charged only if a D406 was checked. (0.5 USDC on Base)
• POST /v1/generate — Create a complete Romanian e-Factura (UBL 2.1, CIUS-RO) from simple JSON: give the seller's and buyer's CUI and the lines (name, quantity, unit, price, VAT rate); company name, address, county code, Bucharest sector and VAT status are filled from ANAF, totals and VAT are computed, and the XML is validated before it is returned. Charged only when a valid invoice is returned. (0.05 USDC on Base)
