Know Your Agent
AI agents are making purchases for your customers. Sentinel tells you who, how much, and flags problems before they become disputes.
Stripe App for monitoring Agentic Commerce Protocol (ACP) transactions.
What Sentinel Monitors
Agent Visibility
See which AI platforms (ChatGPT, Copilot, Perplexity) are making purchases. Track payment volumes and revenue by agent.
Anomaly Detection
Get alerts when agent dispute rates spike, high-value purchases exceed thresholds, or unusual patterns emerge.
Dispute Defense
Agent payment data auto-enriches Reflex dispute evidence. SPT authorization is strong proof of cardholder consent.
Pricing
Sentinel is currently available as a free preview for Stripe merchants. Advanced monitoring, alerts, and compliance reporting are coming soon.
