Is this agent allowed and ready to pay?

A payment protocol is only the transport. Check user identity, out-of-band funding and delegation, a trusted merchant, infrastructure spend limits, idempotent recovery, authoritative logs, Region, live price, and downstream accounting.

Payment gates

Planning result

Complete the checks

Select only controls backed by the real application, AWS account, wallet provider, merchant, and accounting system.

  • Policy decides which tool call is allowed.
  • PaymentSession bounds one payment context.
  • The user funds and delegates outside the agent.
  • Your application validates the recipient and end user.
  • A durable ledger owns cross-session exposure.

Interpret the result

A blocker means the design could expose credentials, pay an untrusted recipient, bypass independent spend control, or duplicate a payment. Do not proceed until ownership and enforcement are redesigned.

A candidate result means the planning gates are present. It does not prove the wallet is funded, delegation is current, the merchant is trustworthy, the Region is supported, or legal and financial review has passed.

Exercise expired sessions, revoked delegation, budget exhaustion, merchant mismatch, signed-proof retry, unknown settlement, provider outage, and reconciliation drift before production.

Keep payment logs outside the model's self-report. AWS vended logs and X-Ray spans, wallet-provider records, merchant receipts, and the business ledger should reconcile by immutable identifiers.

AgentCore payments readiness questions

It checks whether identity, explicit consent, merchant validation, session spend, IAM separation, idempotency, observability, Region, price, and recovery have accountable evidence. It does not inspect AWS or wallet accounts.
No. AWS documents maxSpendAmount as a PaymentSession control for one payment context. Cross-session user, tenant, account, and accounting exposure needs a durable external ledger.
No. AWS says the application must validate payTo because the service does not restrict recipients server-side. Use a trusted request or verified registry and enforce an allowlist; never accept a model-generated address.
