Risksir regression-tests payment policies for safer autonomous x402 agent payments.

About
Risksir is a response-learning layer for autonomous x402 payments. Intercepta provides live risk intelligence before an agent signs a payment, while Risk Sir determines how that specific organisation should respond based on its payment policy and context. When an incident or false positive reveals a poor decision, Risk Sir turns it into a regression case, tests alternative policies against past good and bad payments, and stores validated responses in a company-specific Policy Knowledge Base. This allows payment policies to improve over time without blindly tightening rules and blocking legitimate agent activity.
How it's made
Risksir is built around a real x402 payment flow with Intercepta in the pre-sign decision path. Before a payment is authorised, the selected destination is screened through the live Intercepta API and combined with the organisation’s active payment policy to produce a PAY, CAP, HOLD, REVIEW or DENY decision. Held or denied payments never reach the signer. Every decision stores its payment context, Intercepta evidence, policy version and outcome as a case. A regression engine can then replay proposed policy changes across previous good and bad cases, comparing metrics such as risky value prevented, legitimate payments affected and additional human reviews. Approved policies are versioned and stored in the Policy Knowledge Base, where they can govern future x402 payments while every new payment still receives a fresh Intercepta risk check.
