Stripe Radar Alternative — For Agent Spend
Stripe Radar is the right tool for stolen cards and chargebacks. It's the wrong tool for 'your agent bought from an unknown vendor 40 times.' Here's the alternative layer.
What Stripe Radar does well
Fraud detection on card payments: stolen cards, chargebacks, identity signals.
Automatic blocking of suspicious human purchases.
Where it can't help
Radar flags fraud, not policy violations. To Stripe, a runaway agent's purchases look like legitimate API usage.
No merchant allowlist, category budgets, or approval queue for agent transactions.
The alternative
sipi.bot: a pre-spend firewall that evaluates every agent transaction against your rules before settlement.
