Agent payment infrastructure

Your agent can pay.You stay in control.

Aftercard connects AI agents to payment, identity, and approval workflows without exposing raw credentials to the model.

The controlled loop

From intent to receipt, without leaking authority.

Aftercard adds one governed layer between an agent’s task and the protected action required to finish it.

01
The agent reaches a protected step

The host browser handles the task normally until payment, identity, or another protected value is required.
02
Aftercard checks authority

The request is bound to the exact session, merchant, amount, policy, and approval state before anything sensitive is used.
03
The user stays in control

The user approves when required. Credentials remain outside the model and are applied only to the approved destination.
04
The result is reconciled

Aftercard returns a value-free receipt and a durable payment result that the agent can understand without seeing raw secrets.

One system, three payment modes

Use the right authority for each kind of spend.

A browser purchase, a subscription, and a machine payment should not share one permanent credential or one undifferentiated policy.

Checkout 01

Browser payments

Let an agent finish a real checkout without copying card details, passwords, identity fields, or one-time codes into chat.

Bound to one browser session

Recurring 02

Subscription control

Keep recurring payments separate from one-off spend with clear ownership, limits, approvals, and independent revocation.

Separate policy per subscription

Machine pay 03

API and x402 payments

Give software agents a governed path to pay services and APIs while economic facts stay inside the managed payment flow.

Exact request, exact result

Control before execution

Authority is a policy, not a shared password.

Agents get exactly the permission needed to complete the approved task — nothing broader and nothing permanent.

Scoped authority

Merchant, amount, currency, destination, and time limits travel with the request.

Human approval

Sensitive actions can pause for an explicit decision in the user’s chosen channel.

No raw secrets in the model

Protected values are materialized only at the trusted execution step.

Auditable outcomes

Requests, decisions, payment state, and receipts remain connected for reconciliation.
