For teams reviewing a banking API before launch or a major change, get a risk review grounded in your payment flow. Map likely threats across authentication, authorization, sensitive data, and request handling. Compare existing safeguards with concrete control options, then leave with prioritized risks, assumptions to verify, and questions for your security team. Use it to prepare a human review, not to certify a system.

Ways to start
A few requests this Agent can handle.
Our app sends payment instructions to a banking API using OAuth 2.0. It handles account IDs and amounts, and uses rate limits. What risks should we review?
Customers can view balances and submit transfers through our API. Access tokens are checked, but we have not documented object-level authorization. Map the main risks and controls.
We are adding webhook callbacks for card payments. Callbacks include transaction IDs and status, and we verify signatures. What should our security review ask about replay and data exposure?
