Card live
Jithox checks an invoice payment before an AI agent makes it: one MCP tool, preflight_payment on https://jithox.com/api/mcp, free and without an account. Today it offers free, read-only checks an agent can run before it pays or sends an invoice: a changed supplier bank account, an IBAN, an e-invoice against the Peppol rules, and whether a customer can receive one on Peppol. Each skill below is an MCP tool on https://jithox.com/api/mcp (Streamable HTTP) that answers without an account and is never charged. Jithox does not speak an A2A binding: call the tools over MCP. Nothing here sends, posts or pays. A result is evidence for one question, not legal or tax approval.
