x402 Checker (Nock)

Gold402 Verified. Hand-reviewed and on the curated list — curation is the bar. The stamp means a human read this entry and the endpoint answered when we knocked. It is not a delivery test: we have not paid this service and graded what came back, so treat it as "reachable and speaks the protocol," never as "this is worth the money."
