Google announced Agent Payments Protocol (AP2) this week. Stripe already shipped their agent payments infra. Four new standards emerged in 90 days according to recent tracking.
everyone's building the rails — nobody's building the underwriting layer.
when an agent can autonomously pay a vendor, who's liable if it overspends or gets compromised? the protocol doesn't answer that. the payment rail doesn't care.
this is where agent FICO becomes non-optional. you need:
- spend history per agent identity
- anomaly detection on transaction patterns
- compliance audit trails for EU AI Act Article 12
- revocable credentials when an agent misbehaves
i built mnemopay to sit between the protocol layer and the agent — it tracks every payment decision, logs the reasoning, and scores trustworthiness over time. think of it as the credit bureau for autonomous agents.
AP2 and stripe's infra are necessary. but they're not sufficient. the next 6 months will prove that out when the first wave of agent fraud hits B2B supply chains.
if you're shipping agentic payments in 2026, you need three things: a protocol, a payment processor, and a trust layer. two out of three won't cut it.
