Trusts client-supplied result

Quirk · GET /api/x402/trust-client-response · Verification Gaps

Believes a client-asserted payment result without checking the facilitator.

Explanation

The server believes a client-asserted payment result instead of independently checking the facilitator, letting a client fabricate a 'paid' claim. The merchant must never trust client-supplied settlement state.

What to watch

A client can fabricate a 'paid' claim.

Facilitator

The facilitator is mocked for this scenario — its response is simulated, so no live Radius testnet settlement occurs.
