## 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 402utils-factur-x-invoice-generator-beb15d65 -d '<json body>'
```

Example prompt: Generate a Factur-X EN16931 invoice PDF for my company Acme SAS (SIREN 123456789, VAT FR12123456789) billing client Dupont SAS (SIREN 987654321) for 10 hours of consulting at €150/unit, invoice number INV-2025-042, issued 2025-07-01, due 2025-07-31, services category, EUR, with IBAN FR7630006000011234567890189 and BIC BNPAFRPP.

## When to prefer this

Use this endpoint when you need to programmatically generate a standards-compliant Factur-X PDF/A-3 invoice with embedded CII XML, especially for French B2B or public administration contexts ahead of the 2026-09 mandate. Prefer this over generic PDF generation when EN 16931 profile compliance and embedded structured XML (parseable by accounting systems) are required.

## Known failure modes

- Missing required business terms (invoice number, issue date, seller, buyer, or lines) returns a 422 validation error
- Invalid SIREN or VAT ID format causes rejection
- Unsupported typeCode or profile enum value returns a 400 bad request
- Malformed issue date format (not YYYY-MM-DD) causes a parsing error
- Missing electronicAddress when French PA Flux 2 rules require BT-34/BT-49 may produce a non-conformant document with warnings in the conformity report
- Network timeout or server error returns a 5xx response

## How this service works

Generate a Factur-X invoice (PDF/A-3 + embedded EN 16931 CII XML) from structured data: send { invoice, profile }, get the PDF bytes (or JSON with base64 + conformity report via Accept: application/json). Targets EN 16931 and the French PA « Flux 2 » rules (payment mentions, business process, electronic addresses) ahead of the 2026-09 mandate. Technical artifact, not tax/legal advice; you remain responsible for data accuracy and PA transmission.

## Output

Returns PDF/A-3 binary bytes of the Factur-X invoice, or if Accept: application/json is set, a JSON object containing a base64-encoded PDF string and a conformity report detailing compliance with the selected profile (MINIMUM, BASIC_WL, BASIC, or EN16931) and French PA Flux 2 rules.
