Agent Gateway
The secure connection between AI agents and financial systems.
Route agent requests to approved financial APIs while enforcing identity, permissions, policy and transaction controls.
- AI Agent
- Authenticate Agent
- Verify Permission
- Evaluate Policy
- Execute Action
- Record Audit Event
Core Problem
Agents should never connect directly to unrestricted financial APIs.
Agent systems require an intermediary layer capable of validating identity, checking permissions, evaluating policy and controlling financial tool access before execution.
- Raw API keys grant far more authority than a workflow needs
- Permissions cannot be evaluated inside the model runtime
- Policy must be enforced at execution, not suggested in a prompt
- Every action needs an audit record tied to a principal
Gateway Architecture
Ten checkpoints between intent and execution.
- AI Agent
- Agent Gateway
- Authenticate Agent
- Resolve Principal
- Verify Permission
- Evaluate Policy
- Select Tool / Rail
- Execute Action
- Record Audit Event
Financial Infrastructure
- Payments
- Wallets
- Cards
- Payouts
Core Capabilities
A control plane for every agent request.
