POST /v1/convert

Crée une facture ZUGFeRD/Factur-X validée (PDF/A-3, EN 16931) à partir des données de facturation (JSON ou XML CII) et d'un PDF visuel optionnel. multipart/form-data avec les champs suivants :

Champ	Type	Description
`invoice`	JSON	Données de facturation au schéma eunormia (champ ou fichier). Obligatoire sauf en passage direct XML.
`xml`	fichier/texte	XML CII prêt (passage direct) : intégré tel quel, vérifié par la barrière. Un `pdf` est alors obligatoire.
`pdf`	fichier	Votre PDF visuel (max. 10 Mo). Sans PDF, eunormia génère un modèle par défaut à partir des données.
`options`	JSON	Voir ci-dessous.

Options

Option	Description
`profile`	`EN16931` (défaut), `EXTENDED`, `XRECHNUNG`, `BASIC`, `BASICWL`, `MINIMUM`.
`includeUbl`	Renvoyer en plus le XML UBL 2.1 XRechnung (`ubl`), expérimental.
`kosit`	Valider en plus avec le validateur officiel KoSIT (XRechnung/DE). Résultat sous `report.kosit` — informatif, ne bloque pas la livraison.
`frCtc`	Vérifier en plus les règles CTC françaises (FNFE-MPE). Résultat sous `report.frCtc`.
`sandbox`	Créer volontairement un échantillon filigrané (ne consomme pas de quota).

Réponse

200 : {"pdf": "<base64>", "filename": "…", "report": {…}, "ubl": "…"?}. Le report contient verapdf et xml (toujours PASS — sinon rien n'est livré), watermark, sha256 et, sur demande, kosit/frCtc. Les erreurs métier renvoient 422 avec error, stage et des details compréhensibles — les écarts de totaux ne sont jamais corrigés silencieusement.
