Website health probe: checks whether any URL is currently reachable and returns its response time, content type, and caching behavior. Runs safely against arbitrary user-supplied addresses thanks to built-in request guarding. A lightweight heartbeat for monitoring dashboards, CI pipelines, and pre-fetch validation before a larger crawl.

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