Stripe Radar

Stripe Radar is Stripe's fraud-detection service. Stub page — the 2026-03-12 source touches Radar at the agentic-commerce framing altitude only.

Agentic-commerce adaptation

Per the 2026-03-12 Stripe retrospective, traditional fraud detection relies on human-behavioural signals — browser fingerprinting, mouse movements, device battery level, window size — that vanish in agentic channels where no human is on the frontend.

Radar's substitute for agentic traffic is Stripe network density: even if an agentic purchase is new to the merchant, the end customer and their payment method are usually already known to Stripe across other merchants, which "gives an immediate source of history and risk context."

Integration path with SPTs: authorisation for agentic transactions can happen off-Stripe (at the payment-network level), but Radar can still apply scrutiny because SPTs carry enough metadata for Radar to score the transaction "even when authorization happens off-Stripe."

Claimed outcome on Coach / Kate Spade / Ashley Furniture deployments: "fraud rates have been near zero." (No baseline disclosed; unqualified claim.)
