Issuer-side AI agent authorization
Issuers need a way to authorize agent-originated payments that is transaction-scoped, consent-aware, and auditable. The control plane is simple: verify permission at the moment of authorization, return YES/NO, log proof.
See the decision model.
Run the demo, then map it into issuer authorization stacks.
Why issuer authorization breaks for agents
- Delegation ambiguity: “user allowed it” isn’t bound to constraints and can’t be evaluated transaction-by-transaction.
- Session misuse: long-lived tokens don’t prove permission is still valid now.
- Replay risk: a captured authorization artifact can be reused unless you enforce nonce semantics.
- Audit gaps: logs without cryptographic binding are weak in disputes.
Issuer control model (recommended)
Transaction-scoped consent proof
Use a permission object like a consent receipt that encodes scope and constraints.
Stateless YES/NO decisioning
Evaluate each authorization independently and log a proof record for disputes and audits.
Authorization-time verification flow
- Receive agent-originated context: agent_id + consent_ref + nonce + transaction fields.
- Verify permission: scope/constraints/expiry/revocation + replay safety.
- Evaluate standing & risk: account standing, velocity per agent, category policies.
- Return YES/NO: eligible true/false + proof record.
- Authorize/decline: map decision to scheme response codes; log proof alongside auth event.

FAQ
Where does this sit in an issuer stack?
Inside authorization decisioning, before you respond to the network. Think of it as a permission/consent gate that produces an auditable YES/NO signal.
What’s the minimal integration?
Include agent_id + consent_ref + nonce in the auth context and call verification before final decisioning. Log proof with the auth event.
