POST /v1/x402/merchant-score
unprobed
Probes a counterparty URL for HTTP 402 behavior, valid accepts metadata, and /.well-known/x402 presence. Returns a 0-1 score and label (good | partial | weak). Call before your agent pays an unfamiliar x402 endpoint.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
