Your AI Agent Says the Payment Failed. Did the Money Move? An AI agent reports “payment failed.” Does that mean the money stayed put? A lost response can conceal an executed transfer. A pending operation can reserve funds without paying the recipient. A refund can return principal while leaving fees behind. DN’s new Transaction Outcome Test walks through eight deliberately constructed mock-payment cases—including same-key retries, duplicate payments, partial workflows and separate refunds. The article includes: • Full synthetic results and a downloadable reproducibility package. • Current Stripe and Ethereum documentation explaining the relevant boundaries. • A Transaction Evidence Guide for deciding which records to collect next. These are controlled teaching cases, not a failure-rate ranking of real AI agents or payment providers. Before retrying an uncertain payment, establish what the authoritative records actually show.
