GET /hello

unprobed

Hallo Welt der Nexari GmbH: kleinster bezahlter Test-Endpunkt, gibt Gruß, Zeit und gezahlten Betrag zurück. Hello world from Germany: smallest paid x402 smoke test, returns greeting, timestamp and paid amount.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
