## 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`):

```

Example prompt: Generate an ANAF-compliant e-Factura UBL 2.1 XML for invoice number INV-2024-0042, issued in RON, from supplier Acme SRL to customer Beta SA, with two line items: consulting services 1000 RON and software license 500 RON.

## When to prefer this

Choose this endpoint when you need to generate Romanian ANAF-compliant e-Factura XML documents from structured JSON invoice data, specifically conforming to EN 16931 and CIUS-RO UBL 2.1 standards. It is ideal for automating Romanian electronic invoicing workflows where you already have invoice data in JSON format and need a ready-to-submit XML. Prefer this over generic XML converters because it applies Romania-specific CIUS-RO business rules and ANAF schema requirements automatically.

## Known failure modes

- Missing required fields (lines, currency, customer, supplier, invoiceNumber) returns a validation error
- Invalid currency value outside RON/EUR/USD enum returns a schema error
- Malformed customer or supplier objects cause a 400 bad request
- Empty invoice lines array may result in a rejected or invalid XML
- Network timeout or service unavailability returns a 5xx error

Enterprise microservice and autonomous AI agent hub: ISO 13616 IBAN (#6), Romanian CUI Modulo-11 & EU VIES (#7), UBL 2.1 e-Factura XML (#4), and RFC 9562 UUIDv7 Idempotency (#18).

## Output
