edi.edifact-generate

Generate an outbound UN/EDIFACT document from JSON — the international counterpart to edi.generate (X12). POST type ('ORDERS' = purchase order or 'INVOIC' = invoice) + senderId, recipientId (with optional qualifiers), documentNumber, optional date (CCYYMMDD), parties (NAD role+name, e.g. BY buyer / SU supplier / IV invoicee), items (quantity, productId, price), and for INVOIC an optional total. Returns the full EDIFACT interchange in meta.edi — a correct UNA/UNB/UNH…UNT/UNZ envelope with BGM, DTM, NAD, LIN/QTY/PRI, MOA/CNT — with proper delimiters and release-character escaping. Deterministic, no external calls. Round-trips through edi.edifact.

# 1. Probe the endpoint with no auth — receive 402 with PaymentRequirements
curl -sS -X POST 'https://2s.io/api/edi/edifact-generate' \

# 2. Sign the EIP-3009 transferWithAuthorization for the advertised price +
#    payTo from the 402 envelope, then retry with PAYMENT-SIGNATURE:
curl -sS -X POST 'https://2s.io/api/edi/edifact-generate' \
