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.
/api/edi/edifact-generatePAYMENT-SIGNATURE.The edifact generate API is a pay-per-call edi endpoint built for AI agents and autonomous software. Generate an outbound UN/EDIFACT document from JSON — the international counterpart to edi.generate (X12).
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in edifact generate data source for an agent tool-use loop, an MCP host, or a backend that needs edi data on demand without onboarding to yet another vendor portal.
