MANDATESHIELD FOR ECOMMERCE MERCHANTS

Accept AI-agent orders without trusting the model

Keep the existing checkout and payment processor while adding an execution-time policy check for agent-originated purchases.

Who this is for

Online stores and commerce platforms preparing checkout flows for shopping agents, assistants and agentic browsers.

The execution risk

A valid card or wallet credential proves that a payment method can be used. It does not prove that the customer approved this exact seller, cart, total or delivery context.

How the control fits

  1. Receive the agent checkout and its authorization evidence.
  2. Bind the final cart, total and merchant to the approved mandate.
  3. Run the pre-flight decision before payment confirmation.
  4. Block, review or proceed using exact machine-readable findings.

Controls included

Final-total validationSeller identity bindingCart and intent hashesAuthorization freshnessDuplicate execution preventionMinimal audit receipts

The operational result

Merchants can support agentic checkout without replacing their processor or sending payment credentials to MandateShield.
