# Payment Fraud Prevention — buyer checklist (RFP) Derived from ProductArena's evidence-graded user-story taxonomy for Payment Fraud Prevention: 54 judged requirements. Priorities mirror story weights (3 = must-have, 2 = should-have, 1 = nice-to-have). ## Agentic commerce - [ ] **[should-have]** The product distinguishes malicious bots from legitimate AI buying agents, so agent-driven purchases aren't blanket-blocked as fraud - [ ] **[should-have]** Pass verified agent identity — agentic-payment protocols, signed agent tokens, delegated spending scopes — into the risk decision as a first-class signal ## Agenticness - [ ] **[must-have]** Plug MCP servers into this product so it can use their tools - [ ] **[must-have]** Connect an agent via an official MCP server - [ ] **[must-have]** Drive the product through a documented public API - [ ] **[must-have]** Delegate tasks to a built-in AI assistant inside the product - [ ] **[should-have]** Point an agent at llms.txt or agent-oriented docs - [ ] **[should-have]** Run the product headlessly / in CI for automation - [ ] **[should-have]** Use an official CLI - [ ] **[should-have]** Issue scoped/least-privilege API credentials for an agent - [ ] **[should-have]** Build against official SDKs - [ ] **[should-have]** Subscribe to events via webhooks - [ ] **[should-have]** Get AI-generated insights and suggestions from my data inside the product - [ ] **[should-have]** Set up automations that run autonomously in the background - [ ] **[should-have]** Operate the product with natural-language commands - [ ] **[should-have]** Explore an interactive API reference with runnable examples - [ ] **[should-have]** Download a machine-readable API spec (OpenAPI or equivalent) - [ ] **[should-have]** Rely on versioned APIs with a documented deprecation policy - [ ] **[nice-to-have]** Test against a sandbox environment without touching production data ## Automation depth - [ ] **[must-have]** Define rules that trigger actions automatically on events - [ ] **[should-have]** Perform bulk operations across many items at once - [ ] **[should-have]** Schedule recurring jobs or workflows - [ ] **[nice-to-have]** Version, review, and roll back my automations ## Chargeback disputes - [ ] **[must-have]** Chargeback responses are automated — evidence compiled from order, delivery, and session data and submitted to the issuer without manual copy-paste - [ ] **[should-have]** Shift fraud liability to the vendor — a chargeback guarantee that reimburses approved-then-disputed orders, with clear coverage terms - [ ] **[should-have]** See the numbers that matter — dispute rate, false-positive rate, approval-rate lift, review workload — and export them for the board ## Fraud agent access - [ ] **[must-have]** An agent can read my fraud posture and manage rules and lists programmatically — propose a velocity rule, update a blocklist — with human approval gates - [ ] **[should-have]** An agent can work the review queue — pull flagged cases with their context, summarize the evidence, and recommend a decision for a human to confirm - [ ] **[should-have]** The product ships its own AI assistant — natural-language queries over my fraud data, drafted rules, investigation summaries — built into the console ## Fraud surfaces - [ ] **[must-have]** Use the product across whatever payment stack I run — multiple PSPs, gateways, and platforms — rather than being locked to one processor's rails - [ ] **[should-have]** Protection extends beyond checkout — account takeover, fake account creation, promo and policy abuse are scored and managed in the same system - [ ] **[should-have]** There are maintained integrations for my commerce stack — Shopify, Salesforce Commerce, BigCommerce, and the major PSPs — not just a raw API ## Model transparency - [ ] **[must-have]** Every score comes with its top risk factors — why this transaction looks risky — not just an opaque number - [ ] **[should-have]** Measure the model itself — precision and recall on my traffic, shadow-mode trials of new models or rules before they take over decisions ## Openness - [ ] **[must-have]** Export all of my data in open formats and leave - [ ] **[must-have]** Self-host the core product - [ ] **[should-have]** Do everything through the API that I can do in the UI - [ ] **[should-have]** Read the product's source under an open license ## Privacy posture - [ ] **[must-have]** Prevent my data from being used to train AI models - [ ] **[should-have]** Choose where my data is stored (region/residency) - [ ] **[should-have]** Control data retention and deletion - [ ] **[should-have]** Opt out of telemetry and usage tracking ## Residency compliance - [ ] **[should-have]** Control where fraud data lives and how long it's kept — regional residency options and retention controls that survive a privacy review - [ ] **[should-have]** European traffic is routed intelligently through SCA — 3DS triggered when required or risky, exemptions requested when safe — to protect both compliance and conversion ## Review queues - [ ] **[must-have]** Flagged transactions land in a review queue that shows the full context — customer history, signals, similar cases — so I can decide quickly and consistently - [ ] **[should-have]** My review decisions and confirmed fraud outcomes feed back into the model and rules, so the system learns from every case we work - [ ] **[should-have]** Review work is a team workflow — assignment, escalation, SLAs, and a decision audit trail that shows who approved what and why ## Risk scoring - [ ] **[must-have]** Get a machine-learning risk score for a transaction in real time — synchronously, before authorization completes — through a documented API - [ ] **[should-have]** Feed the model my own signals — device fingerprints, behavioral data, custom metadata — so scoring reflects my business, not just network defaults - [ ] **[should-have]** Scoring benefits from a cross-merchant network — a card or identity seen across thousands of other businesses informs the risk decision on mine - [ ] **[should-have]** Map score ranges to actions — allow, review, block, step-up 3DS — and tune thresholds to my own risk appetite instead of a fixed cutoff ## Rules engine - [ ] **[must-have]** Author custom rules that combine model scores, velocity counters, list matches, and transaction attributes into allow, block, or review decisions - [ ] **[should-have]** Backtest a rule against my historical traffic before deploying it, seeing exactly what it would have blocked, flagged, and cost - [ ] **[should-have]** Maintain allow and block lists — emails, cards, devices, IPs — and velocity limits, managed through the dashboard and programmatically --- Source: https://ultrametric.ai/productarena/arena/fraud-prevention (evidence-graded verdicts for 5 products) · methodology: https://ultrametric.ai/productarena/methodology
