01
Check the agent purchase
For $0.01, validate a real 402 challenge against advertised price, protocol, network, asset, destination, resource binding, and recovery signals before authorizing the target payment.
Pre-payment safety and reversibility for AI agents
Before your agent pays, know what it is authorizing.
ExitProof checks machine-payment challenges before autonomous purchases, surfaces retry and recovery risk, and preserves bounded exit evidence for real-world commitments.
Purchase intentWhat the agent plans to buy and the commitment it is considering.
Payment boundaryPrice, protocol, asset, destination and recovery signals before funds move.
Exit conditionsCancellation, refundability, deadlines, penalties and uncertainty.
Durable exit recordPrivacy-minimized facts the agent can recover later if the commitment needs to be unwound.
How it works
A safety primitive before autonomous commerce.
ExitProof does not decide whether an agent should buy. It makes the payment boundary and the exit path more legible before money moves.
02
Check reversibility
For real-world commitments, send structured checkout terms. ExitProof classifies the exit path, deadline, possible loss, and uncertainty for free.
03
Preserve the exit path
An eligible Exit Manifest is $0.25. If an exit is later needed, a $1.00 exit pack turns the stored evidence into bounded next steps.
Exit Manifest
The receipt for changing your mind.
The durable object is intentionally small and machine-readable. It preserves the facts an agent is most likely to need later without storing a user's full conversation or checkout payload.
Reversibilityfully, conditionally, low, irreversible, or unknown
Free exit deadlineexact timestamp when the supplied terms establish one
Maximum stated lossinteger minor units, never a guessed conversion
Exit methodthe recorded cancellation path or policy source
Evidencetransaction-term digest plus maintained official sources
Privacyunguessable manifest ID + one-time access token; token stored only by hash
Boundaries
Conservative by design.
Autonomy becomes safer when the specialist is willing to say that an exit path is not established.
ExitProof can establish
- what structured transaction terms say about cancellation and refundability
- stated deadlines and penalties
- maintained official policy context where available
- whether the evidence is strong enough to preserve or build an exit pack
ExitProof does not claim
- that a merchant will approve a refund
- that a missing policy means no legal right exists
- legal advice or chargeback authority
- that a reversible purchase is a good purchase
- merchant contact or automatic cancellation in V1
Live
ExitProof is live for agent use.
The agent-purchase preflight is $0.01 on compatible stablecoin machine-payment rails after its own safety gate succeeds. The reversibility assessment remains free, a durable Exit Manifest is $0.25, and an actionable exit pack is $1.00. Payment buys bounded safety and evidence infrastructure, never purchase approval or a guaranteed outcome.
