MANDATESHIELD FOR PAYMENT PROVIDERS
Pre-authorization control for agentic payments
Separate the question 'is this payment credential valid?' from 'did the user authorize this autonomous purchase?'
Current support boundary
This page describes an architecture pattern, not evidence of a customer deployment or provider adoption. Terminal outcome checking currently covers configured Stripe PaymentIntents and the supported x402 EIP-3009 profile only. Production requires provider credentials to be absent from the agent and alternate provider egress to be blocked. If native controls already satisfy the complete requirement, an additional MandateShield boundary may be unnecessary.
Who this is for
Payment processors, orchestration platforms, wallets and fintech infrastructure serving autonomous commerce.
The execution risk
Fraud scoring, card authorization and sanctions checks answer different questions from agent authority. Agent payments require an explicit policy decision tied to the user's mandate.
How the control fits
- Register immutable mandate policy and trusted issuer keys in the account control plane.
- Issue a one-time challenge and accept signed final-checkout facts from the merchant.
- Return a fail-closed ALLOW, REVIEW or BLOCK and atomically reserve cumulative headroom for qualifying ALLOW.
- Use an audience-bound PROCESSOR credential to issue and redeem one provider-bound permit, then record the submission hint for supported-provider reconciliation that does not trust the caller assertion.

The operational result
An integrator can add a normalized agent-authority boundary without claiming complete conformance with every labeled protocol.
