AFFIXIO
Payment permission
AI agents need verifiable payment permission
If an agent can spend, you need a cryptographic record of permission. AffixIO provides signed allow or deny for payment policy at the boundary, with Merkle audit references for later review.
Definition
Agent payment permission is a signed allow or deny that policy authorised an agent to initiate a specific class of spend.
Field note. Agents that reach the PSP without upstream verify create chargebacks your team cannot defend with logs alone.
Start here, then go deeper
This page is the short path. For full treatment of payment permission, consent, and merchant gates, read the longer trends article and the agentic payments sector guide.
In practice: issue permission, verify at pay, retain Merkle refs. Card data stays with your PSP.
Sandbox first
Prove a payment-policy circuit in the sandbox before wiring production checkout. Map deny handling early so support is not surprised.
Compare agent auth versus API keys when stakeholders ask why shared secrets are not enough.
Integration notes for agent payment permission
Wire AffixIO verify immediately before the boundary where agent payment permission applies: checkout authorisation, MCP tool invocation, age gate, or offline scan. Issue proofs when policy is satisfied. Present at the edge. Gate on signed allow or deny.
Train support on deny retrieval: Merkle ref lookup should not require engineering access. Document which circuit version was active when the proof was issued.
Merchant pain
Spend without a permission artefact
API access is not payment authorisation. Agents that can call a pay endpoint need a scoped, auditable permission outcome.
Keys mistaken for consent
Holding a secret is not proof of user or treasury approval for this payment.
Missing audit binding
Transaction logs without signed permission leave dispute teams guessing.
No quick path for teams
Engineers need a short guide before the longer sector deep dive.
Audit posture
Wire verify before your agent touches the wallet
Production agent checkout depends on binary gates: allow or deny, verifiable without raw identity files. AffixIO issues payment permission proofs at policy satisfaction and checks them one hop before capture.
