B2A Agentic Commerce Implementation Record

A dated technical record of a working business-to-agent (B2A) commerceimplementation. A third-party software agent, acting on behalf of a buyer,can read a priced catalogue, place an order, accept an offer pinned to acontent hash, and settle payment using a delegated one-time paymentcredential, without a human at a checkout screen.The record documents the architecture, the four client classes and theirseparated authority, the offer-integrity mechanism, both settlement paths,and a dated verification log with redacted evidence for each capability. Italso records a defect found during verification, in which a test-mode paymentconsumed a real invoice number, and the safeguard introduced in response.The record states explicitly what was verified in production and what wasverified in a test environment. Version 1.1 corrects a conclusion drawn inversion 1.0: shared payment tokens are issued by the agent, from a paymentmethod the buyer supplied, and are supported for agents, customers andsellers in Bulgaria and across most of Europe. Only the processor's ownconsumer wallet limits agent connections to accounts in the United States.
