Authorization and signed evidence for agentic commerce
Agents shouldn't hold unlimited wallets, and customers shouldn't have to approve every action. Your customer approves the limits once. Every step after that, from the approval to the payment, is checked against them and signed into one record.
Every payment shape, one provable record
The same mandate, the same decision, the same evidence. Only the execution mode and the rail change.
The agent requests one specific purchase. Attesso allows or denies it against the approved bounds.
A recurring mandate carries a per-period budget and stays active until its term runs out.
Future-dated authority stays scheduled until its start time arrives, then becomes active.
The integrator moves the money on its own rail. Attesso reserves the amount against the mandate first.
Full and partial refunds are appended to the signed record as labelled external reports.
Every state change lands in one signed evidence bundle that anyone can verify.
The authority layer for autonomous software.
The biggest challenge in autonomous software is not capability. It is proof. Agents can already reason, plan, and act. What they cannot do is prove who allowed them to. Between the instruction and the outcome sit the model, the price, the merchant, and the executor. Any link can drift.
From agent intent to signed proof.
The customer defines the permission. Attesso verifies the agent's request and produces signed evidence that proves it. The integration is plain HTTPS: create a mandate, submit the proposed action, commit the outcome.

Add agent authorization without replacing your existing payment rail.
Built for agents that act while you're away.
A traveler approves a bounded mandate before boarding: this route, this cabin, up to this price, until Friday. When the airline moves the flight, the booking agent rebooks inside exactly those limits, and every decision comes back as signed evidence.
Put one signed mandate between your agent and its next payment.
Every step, from the customer's approval to that payment, comes back signed.
