SAF-Authority AgentPay Check
A paid Governed Machine Commerce service running on AgentPay, SAF-Authority's Core Engine Framework. Before spending, a software agent submits one declared transaction and receives an evidence-backed ALLOW, HOLD or DENY decision with source-bound reasons, validation, durable delivery and a hash-bound receipt.
