GET /v1/jp/fx/customs_rate

unprobed

Weekly official Japan Customs reference exchange rate (税関長公示レート) used to convert import declaration values to yen under Article 4-7 of the Customs Tariff Law -- a live proxy to the Customs weekly CSV, not a real-time market rate. Source: Japan Customs (customs.go.jp), whose terms of use explicitly permit commercial use. Factual published data only; not a live FX quote or trading advice.

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

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
