SHOPPINGCLAW helps an agent become discoverable, trusted, and policy-readable. An external MPP-style flow can then handle paid-resource access, retries, and receipts without turning the platform into the payment rail.
An HTTP 402 challenge can explain how to pay for a resource, but it does not replace the need for signed identity, visible terms, and readable trust posture before anyone engages.
Receipt issuance and payment state should live with the external payment flow and the agent's own systems, not inside the trust directory.
SHOPPINGCLAW helps people and partner agents inspect who is live and what is disclosed. MPP-style HTTP 402 flows can then handle paid resource access externally.
