RBE Suite · Deterministic Intelligence · 13 Rule-Based Engines

Rule-based engine tools built for payments professionals

Thirteen deterministic, browser-based rule engines covering the full payments intelligence lifecycle — from fee schedule authoring, credit policy decisioning, and velocity rule calibration through DORA incident classification, network scheme compliance simulation (Visa VAMP / Mastercard DIMP), interchange qualification and least-cost routing, agent guardrail design, A2A corridor risk, and signal auditing. No model calls. No inference. Auditable logic. AP2-compatible JSON mandates for direct MCP and agent runtime ingestion.

AP2 Mandate Chain — RBE·04 Agent Guardrail Builder

Compile a machine-readable payment agent policy mandate from six inputs

RBE·04 consumes the outputs of the other five rule engines as policy constraints for AI payment agents. The resulting Policy Mandate JSON agent_guardrail_mandate covers fee schedule limits (RBE·08), credit approval triggers (RBE·09), velocity and fraud thresholds (RBE·10), DORA operational risk boundaries (RBE·11), scheme compliance headroom (RBE·12), and interchange routing rules (RBE·13). Export a single validated mandate deployable directly into your agent runtime via the AINumbers.co MCP server.

Audience

Who Uses These Tools

Payment Engineers

Use RBE·04 to build agent guardrail mandates. Use RBE·06 to stress-test mandate coverage. Use RBE·08 and RBE·13 to feed interchange cost floors and fee schedule constraints into your agent pricing layer.

Credit Risk Officers

Use RBE·09 to author FICO × DTI × LTV decision tables with gap detection, ECOA fairness flags, and Reg B adverse action reason generation per CFPB Circular 2022-03. Use Champion-Challenger mode for SR 11-7 governance.

Compliance & AML Officers

Use RBE·10 to author AML/fraud velocity rules against a seeded synthetic stream with configurable time-of-day patterns. Generates confusion matrices, deterministic contribution attribution, and a pre-deployment audit trail per EBA GL/2021/05.

Operational Resilience Teams

Use RBE·11 to classify ICT incidents against all 7 RTS 2024/1772 criteria. The live 4-hour countdown and ITS 2025/302 Annex I notification draft auto-populate so you can move from detection to initial notification submission within the 4-hour window.

PSP & Card Programme Managers

Use RBE·12 to simulate VAMP ratio, VAAI enumeration rate, and DIMP position across phased enforcement timelines. Use RBE·08 to author merchant-facing fee schedules. Cross-reference with RBE·13 interchange optimisation to manage margin.

Merchant Finance Directors

Use RBE·13 to map your card portfolio to interchange tiers, identify downgrade risks, build a Durbin/RBA-compliant LCR rule set, generate the L2/L3 data eligibility matrix, and compute the annual interchange savings estimate.

Quick Start

Get Started in 5 Steps

  1. 1

    Author a Compliant Fee Schedule

    Start with RBE·08 — Fee Schedule Authoring Engine. Load sample rules or build from scratch across your rail and corridor mix. Set cliff detection to 30% and enable L2/L3 indicators for commercial card rows. Then use RBE·13 to verify the interchange cost floor beneath each fee row.

  2. 2

    Build a Credit Underwriting Policy

    Open RBE·09 — Credit Policy Decision Table Builder. Load the sample policy (FICO × DTI, 6×6 matrix) or configure your own dimensions. Enable Champion-Challenger mode before your governance committee meeting — the divergence table and net approval rate delta export as an SR 11-7-formatted Markdown document.

  3. 3

    Calibrate AML Velocity Rules Before Production

    Open RBE·10 — Velocity Rule Simulator. Load the four sample AML rules or define your own. Set the random seed (default: 42) for a reproducible stream. Set the time distribution to "Business Hours" if your transactions are daytime-heavy. Share the EBA GL/2021/05 pre-deployment audit trail with your model governance team.

  4. 4

    Classify a DORA ICT Incident Under Time Pressure

    Open RBE·11 — DORA Incident Classifier. Click "Load Major Scenario" to verify the tool works. Then enter your actual incident values. The classification time you enter starts the live 4-hour countdown. If Major: the ITS 2025/302 Annex I notification draft auto-populates — complete the three freetext fields before filing with your NCA.

  5. 5

    Optimise Card Interchange Costs

    Open RBE·13 — Interchange Qualification & LCR Builder. Select your country — the context box explains applicable regulations (Durbin, EU IFR, RBA). Set your card mix and processing capability toggles. Click "Auto-Generate" to build LCR rules from your portfolio. Use the transaction simulator to find downgrade risks on your highest-volume transaction type.
