• check_ssl

  Fetches and evaluates a host's TLS certificate over a live handshake: subject, issuer, validity window, days until expiry, hostname match, chain trust, self-signed and expired flags, SANs, serial and SHA-256 fingerprint. Takes a hostname…

• check_dns

  Resolves a domain's DNS records in one call (A, AAAA, CNAME, MX, TXT, NS, SOA and more) and returns each record type with its values, or a per-type error where a lookup failed. Answers come from a single resolver; dns_propagation compares…

• dns_propagation

  Queries one domain against several public resolvers and compares the answers, which tells a recent record change apart from a stale cache. Returns each resolver with its values and a `consistent` flag that stays false while the answers…

• mx_lookup

  Looks up a domain's MX records and resolves each mail exchanger to its IPv4 and IPv6 addresses, ordered by priority, flagging hosts that resolve into private address space. Shows where mail is delivered; it does not connect to the servers…

• spf_check

  Fetches a domain's SPF record and evaluates it: raw record, parsed terms with qualifiers, DNS lookups counted against the RFC 7208 limit of ten, the final `all` qualifier, and warnings for common silent failures. A domain without a record…

• dkim_check

  Fetches and validates the DKIM public key at <selector>._domainkey.<domain>: parsed tags, key type, key size and warnings such as a revoked or malformed key. The selector is required and cannot be derived from the domain; it appears in a…

• dmarc_check

  Fetches a domain's DMARC record from _dmarc.<domain> and evaluates it: raw record, parsed tags, policy and subdomain policy, percentage, and warnings for records that parse but offer no protection (p=none, missing rua). Reports the…

• dnsbl_check

  Checks a public IP address against common DNS blocklists and returns, per list, whether it is listed, the list's reason code and delisting URL, plus totals and a `clean` flag. Takes an IP address, not a domain (mx_lookup or check_dns…

• whois

  Retrieves WHOIS registration data for a domain: registrar, creation, update and expiry dates, EPP status codes, nameservers and the contact roles the registry still publishes (personal data is usually redacted). tldSupported=false means…

• domain_expiry

  Reports a domain's registration expiry from WHOIS with the remaining days, plus registrar, creation and update dates and the EPP status codes that reveal redemption or pending delete. Covers the registration, not the TLS certificate…

• http_headers

  Fetches a URL and returns its HTTP response headers verbatim as a name/value map, with the status line and every redirect hop. The response body is never returned. website_status gives a plain up/down verdict and redirect_check the…

• hsts_check

  Checks a domain's HTTP Strict Transport Security setup: header presence and raw value, max-age, includeSubDomains and preload flags, whether plain HTTP redirects to HTTPS, preload-list eligibility, and warnings for ineffective values…

• redirect_check

  Follows a URL's redirect chain hop by hop and returns each step's status, source and target, the final URL and status, the hop count, and warnings for loops, HTTPS-to-HTTP downgrades and overly long chains. Body and headers of the…

• port_check

  Opens TCP connections to one port or a list of up to 10 ports on a host and reports each as open, closed or filtered, with the time taken. partial=true means not every port answered within the time budget; filtered means no answer…

• ping_test

  Measures reachability and round-trip time with repeated TCP connections to a host port (default 443), returning every attempt, sent and received counts, packet loss and min/avg/max milliseconds. A TCP handshake, not an ICMP echo, so hosts…

• website_status

  Checks whether a website is up right now: up/down verdict, HTTP status and text, response time, server header and number of redirects followed. The usual first call for any is-the-site-down question. A single sample from one location, not…

• response_time

  Measures how fast a URL answers over several samples, returning each sample plus min, average and max milliseconds, the HTTP status and an `up` flag. partial=true means fewer samples returned than requested. Measures the HTTP response…

• ip_geolocation

  Locates a public IP address, or a domain resolved to one, at network level: country code, registry, announced prefix, PTR hostname and autonomous systems. Registry-based, so it names the network operator's country, which for hosted or CDN…

• asn_lookup

  Resolves a public IP address, or a domain, to the autonomous system that announces it: AS number and name, announced prefix, country code, registry and allocation date. Distinguishes hosting providers, CDNs and corporate networks; it does…

• reverse_dns

  Resolves a public IP address to the PTR hostnames published for it, or returns the resolver's error where there is none. A PTR is set by whoever controls the address block, so it names the host rather than necessarily the site; a missing…
