Runtime controls
Policy Engine
Define the rules for how agents spend, then evaluate every payment request before funds move. Conto keeps limits, categories, trust requirements, and approval rules in the transaction path.
Decision point
Before settlement
Rule types
Limits, trust, categories, velocity
Outcome
Approve, deny, or route
Capabilities
Policy controls built for the payment decision
Use policy primitives that evaluate spend at the moment an agent asks to move money.
Spend limits
Set per-transaction, daily, weekly, monthly, and scoped limits by agent, wallet, merchant, category, or project.
Counterparty rules
Require trusted recipients, block risky addresses, and route unknown counterparties to review.
Velocity controls
Catch broken loops, retry storms, and unexpected payment bursts before a wallet is drained.
Approval thresholds
Let routine payments clear while higher-risk requests pause for human review with full policy context.
Workflow
How policy decisions shape each payment
The engine sits between agent intent and settlement, turning configured rules into approve, deny, or route decisions.
Step 1
Configure rules
Create policies for the agent, wallet, payment rail, category, counterparty, or approval path.
Step 2
Evaluate every request
Conto checks the payment request against active policies when the agent tries to pay.
Step 3
Return a clear decision
Approved payments continue, denied requests stop, and exceptions route into approval workflows.
Visibility
Policy outcomes your teams can inspect
Finance, operations, and security can see which rule fired, why it fired, and what happened to the payment next.

Outcomes
What changes when policy runs at transaction time
Agents can transact autonomously without bypassing financial controls.
Finance and security see the exact policy decision behind each payment.
Control changes happen in one platform instead of scattered runtime code.

Escalation paths
Approval routing for high-value or ambiguous payment decisions
Some payment decisions need a pause, not a hard stop. Agents can keep moving on the standard path while the payment layer pauses only the transactions that need human approval.

Vendor and counterparty controls for autonomous payments
Trusted vendors should clear quickly, and new counterparties should not slip through unnoticed. Conto keeps vendor, merchant, and service-provider policy attached to the payment path so recipient drift is caught immediately.

x402/MPP and service-spend budgets for machine payments
When agents are paying for APIs, inference, or compute by the call, Conto applies per-request caps and session budgets so service spend stays bounded even when the agent is making many decisions per minute.
