Use cases

Approve once. Let the agent finish.

Attesso authorizes a delayed action against the exact boundary a user signed, and returns signed evidence. You keep your own execution rail.

Design-partner focus

Travel platforms

Book or rebook after the traveler leaves, within the exact route, cabin, date, and amount they approved.

  • Rebook within the approved route, cabin, date, and total-price limits as inventory changes
  • Hold hotel reservations to the property, stay dates, room, and nightly or total limits
  • Return signed evidence of exactly which booking the traveler authorized

Discovery

Procurement platforms

Release a supplier award or purchase order only against supplier and amount limits the approver already signed.

  • One supplier award or purchase-order release, checked against signed limits
  • Explicit supplier, item, quantity, currency, amount, and expiry constraints
  • Fail closed whenever a boundary cannot be established

Partnership

Payment and execution partners

Attach mandate enforcement and signed evidence to the credential, payment, or execution rail you already run.

  • Bind a provider credential to the authorization lease, action digest, and fencing epoch
  • Serialize provider acceptance against terminal invalidation
  • Return signed, ordered finality evidence without moving money

Personal use

Use Attesso with your own card.

You are the only party. Your payment rail is a personal card or a virtual credit card, and you want an agent to spend within bounds you approve, with proof.

A single workspace is all you need: create one, grab a free test key, and follow the guide — no merchant account or full PSP integration required.

Read the guide
  • Personal use: an agent spends your own money within bounds you approve, with signed evidence.
  • Solo developers: exercise a real card charge end-to-end without a merchant account or full PSP integration.
