payable

Uptime/health probe for any public URL: sends a HEAD request (auto GET fallback when the server refuses HEAD), follows redirects with per-hop safety checks, and returns up/down, HTTP status, latency in ms, redirect chain, final URL, and key response headers. Deterministic, no page download — a monitoring probe agents can call on a schedule.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
