FastRisk-Jev is a demo of a real-time fraud check for payments. You enter a user, an amount, a location, a device type and a note about what the user did just before, then press run.
Jev answers three typed questions about that one payment: is it likely fraudulent, which kind of fraud attempt it resembles, and what action it needs, from direct approval to a one-time code check to blocking it at once. The page shows the decision with a plot.
You bring your own OpenRouter key, which the page says is passed straight to OpenRouter and never stored. Two example payments are built in, a routine coffee order and a risky wire from a hidden connection.
