check_endpoint
Check whether a URL answers a well-formed x402 (HTTP 402) payment challenge — the question an agent host asks before routing a paid call. Free. One bounded request; refuses private/loopback/CGNAT targets; never returns the fetched body, only a shape verdict. This is a free shape check, NOT a conformance report.
