Per-call decisions
Every paid request is checked before the provider is paid. Low-cost calls keep flowing, while an oversized call or an exhausted session both stop without a human in the loop.

Conto checks policy
Budgets, per-call caps, and approvals are evaluated before spend.

Service-spend activity with budget context attached
Machine-speed payments show up with the same context as enterprise approvals and budgets, which makes service-spend automation easier to govern alongside the rest of the payment estate.
Payment request
Rules evaluated
Routed to review
1 of 4 rules needs a human before settlement.
Controls that bound automated service spend
Per-call, session, provider, and velocity policies stop runaway spend without forcing every low-cost request into manual review.
Per-call ceilings
Prevent a single API or inference request from blowing past the allowed unit economics for the task.
Session envelopes
Give each task or agent run a hard budget so many small calls cannot add up to an unlimited bill.
Provider-level policy
Restrict autonomous spend to the providers or service types you actually trust for the workflow.
Velocity monitoring
Catch broken loops or runaway retry behavior before the agent can hammer a paid endpoint continuously.
How per-call payments stay inside budget
Agents can buy APIs, inference, and compute on demand while Conto checks unit economics and task budgets before each paid request.
Step 1
The agent chooses a paid service
A compute or API workflow selects the service endpoint and proposes the call based on price, latency, or task fit.
Step 2
Conto checks call-level economics
Conto checks each request against your per-call limits, session budgets, and provider rules before the service is paid.
Step 3
Normal usage continues until budget is spent
Low-cost calls keep flowing. Expensive routes or exhausted budgets are blocked before the provider is paid.
Demo
Watch per-call payments stay inside a session budget
A buyer agent selects inference providers call by call. Per-request ceilings, session budgets, and velocity checks keep low-cost usage flowing and block spend that exceeds the task envelope.

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.

Agent Wallets
Give each agent a wallet that can be governed by policy, monitored by finance, and connected to the payment workflows it owns.

Audit and Reconciliation
Attach agent, counterparty, policy, approval, and execution context to every transaction so finance can understand what happened without chasing separate systems.
Explore productMachine payments that stay in budget
Engineering teams can let agents buy services dynamically without accepting unbounded cost exposure.
The same control plane works for per-call infrastructure spend and more traditional payouts.
Every paid request comes with a budget story that finance can understand.
