POST /feedback
method-gated
Otto X402 Router — Feedback & Refunds. Rate a paid Router call by its payment tx_hash. An approved refund returns this $0.001 fee PLUS the refundable amount, only to the original payer, never above what you paid Otto.
Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.
