check_url — Is a page up right now: HTTP status, response time, server, redirect chain and the first text on the page.
check_endpoints — Up/down sweep of up to 10 URLs in one call, with status code and response time for each.
port_monitor — Check whether TCP ports on a host accept connections, with the service usually found on each port.
ssl_expiry — Days left on a site's TLS certificate, who issued it and whether the chain is trusted.
dns_health — A, AAAA, NS, MX, TXT and CAA records for a domain, plus whether SPF is published.
monitor_report — One call that runs the whole monitor sweep on a URL: reachability, TLS certificate and DNS, with a verdict.

Setup

No setup. Every check runs live from the server itself, so there is no key or account.

Licence — no paywall

Every tool in this package is free: no licence key, no premium tier, no hosted licence gateway. The paywall machinery this repo once carried (per-tool licence checks and paid hosted endpoints) was removed repo-wide on 2026-10-17. Nothing that this package installs or calls asks you to pay.
