GET /mcp
method-gated
The Federal Acquisition Regulation, current to eCFR, searchable by meaning. FAR Desk's search tool, one call. A pass (POST https://far-desk.quickbeam.workers.dev/pass) covers every call.
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.

curl -si -X GET 'https://far-desk.quickbeam.workers.dev/mcp' -H 'accept: application/json'
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.
