## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saf-t-d406-validator-for-anaf-romania-c6002d3e -d '<json body>'
```

Example prompt: Can you validate my Romanian SAF-T D406 XML file before I submit it to ANAF? It's the monthly declaration — please check it with both the official ANAF rules and the extended consistency checks like balanced entries, VAT base-times-rate, and CUI/IBAN digit validation, and give me fixes in English for anything wrong.

## When to prefer this

Choose this endpoint when you need to pre-validate a Romanian SAF-T D406 XML (monthly, annual assets, or stock) before submitting to ANAF, especially when you want both the official DUKIntegrator checks AND deeper consistency checks (balanced entries, VAT arithmetic, roll-forwards, CUI/IBAN digits) that ANAF's own tool skips. Prefer it over manually running DUKIntegrator when you need bilingual fix guidance or automated pipeline integration.

## Known failure modes

- XML file exceeds 100 MB limit — request rejected
- Malformed or non-SAF-T XML body — parse error returned
- Network timeout for very large files near the size limit
- Invalid or missing required XML elements — error reported in findings
- Charge only applies if a D406 was actually validated; non-D406 XML may not be billed but returns an error

## How this service works

Check a Romanian SAF-T D406 file (monthly, annual assets, stock) before filing with ANAF: the official ANAF validator (DUKIntegrator) plus the consistency checks it skips - balanced entries, opening + movements = closing per account, partner balances, invoice totals, VAT = base x rate, VAT codes for the period, exchange rates, CUI/IBAN check digits, asset and stock roll-forwards. Each finding has a fix (RO/EN). XML as the request body, up to 100 MB. Charged only if a D406 was checked.

## Output

A structured report of all validation findings, each with a severity, description, and suggested fix in both Romanian and English. Covers ANAF DUKIntegrator rule violations plus extended checks: balanced accounting entries, opening + movements = closing per account, partner balances, invoice totals, VAT = base × rate, VAT code validity for the period, exchange rates, CUI/IBAN check digit errors, and asset and stock roll-forward discrepancies.
