A PTR is set by whoever controls the address block, so it names the host rather than necessarily the site running on it, and a missing PTR is common and not a fault. It is not the inverse of check_dns: a forward record and a PTR need not agree, and this call does not verify that they do. Anonymous and rate-limited per IP.
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 PTR is common and not a fault. Forward and reverse records need not agree, and this call does not check that they do. Anonymous, rate-limited per IP.
asn_lookupchangedtitle, description, annotationsResolve a public IP address, or a domain, to the autonomous system that announces it: AS number and name, the announced prefix, country code, registry and allocation date. Answers who operates the network an address sits on, which tells a hosting provider from a CDN from a corporate network. It does not identify the site owner, and private or reserved addresses have no announcing AS. ip_geolocation returns the same AS data plus country and PTR. Anonymous and rate-limited per IP.
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 not identify the site owner. Private and reserved addresses have no announcing AS. ip_geolocation returns the same AS data plus country and PTR. Anonymous, rate-limited per IP.
ip_geolocationchangedtitle, description, annotationsLocate a public IP address, or a domain resolved to one, at network level: country code, allocating registry, announced prefix, PTR hostname and the autonomous systems the address belongs to. It is registry-based, so it names the network operator's country, which for hosted or CDN-fronted addresses is not where the visitor or the business sits -- never read it as a street address. Private and reserved addresses have no answer. For the AS and its owner alone use asn_lookup, for the PTR alone reverse_dns. Anonymous and rate-limited per IP.
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 addresses differs from where a visitor or business is located; it is not a street address. Private and reserved addresses have no answer. Anonymous, rate-limited per IP.
response_timechangedtitle, description, annotationsMeasure how fast a URL answers by taking several samples and returning each one plus min, average and max milliseconds, the HTTP status and an up flag. partial=true means fewer samples came back than were requested, so the average rests on a smaller base. This measures the response, not the rendered page: no browser runs, so nothing here reflects JavaScript, assets or Core Web Vitals. One call is a snapshot, not a trend. Anonymous and rate-limited per IP; private and reserved address space is refused.
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 only: no browser runs, so JavaScript, assets and Core Web Vitals are not reflected. A snapshot, not a trend. Anonymous, rate-limited per IP; private and reserved addresses are refused.
website_statuschangedtitle, description, annotationsIs a website up right now? Start here for any is-the-site-down question: up/down verdict, HTTP status and status text, response time in milliseconds, the server header and the number of redirects followed, in one call. This is a single sample from one location taken now -- it is not uptime, and a site that fails here may be reachable from elsewhere. For the timing breakdown use response_time, for the headers themselves http_headers, for the redirect chain redirect_check. Anonymous and rate-limited per IP; private and reserved address space is refused.
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 uptime; response_time, http_headers and redirect_check go deeper. Anonymous, rate-limited per IP; private and reserved addresses are refused.
ping_testchangedtitle, description, annotationsMeasure reachability and round-trip time by opening repeated TCP connections to a host, reporting every attempt plus the count sent and received, packet loss percentage and min/avg/max milliseconds. This is a TCP handshake against a port (default 443), not an ICMP echo: a host that drops ICMP still answers here, and a host that answers ICMP with the port closed does not. For a one-shot verdict on a website rather than a latency series, use website_status. Anonymous and rate-limited per IP; private and reserved address space is refused.
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 that drop ICMP still answer. website_status gives a one-shot verdict for a website. Anonymous, rate-limited per IP; private and reserved addresses are refused.
port_checkchangedtitle, description, annotationsOpen a TCP connection to one or more ports on a host and report each as open, closed or filtered with the time the attempt took. Pass a single port or a list of up to 10; a single-port call also gets its answer flat, exactly as before the list form existed. partial=true means not every requested port was answered inside the time budget. TCP only -- there is no UDP check -- and filtered means no answer arrived, not that the port is certainly closed. Anonymous and rate-limited per IP; the host is resolved first and private or reserved addresses are refused, including a host whose DNS answer points into them.
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 arrived, not that the port is certainly closed. TCP only, no UDP. Anonymous, rate-limited per IP; hosts resolving to private or reserved addresses are refused.
redirect_checkchangedtitle, description, annotationsmeaning changedFollow a URL's HTTP redirect chain hop by hop and return every step with its status code, source and target, the final URL and status, the hop count, and warnings for chains that loop, drop from HTTPS to HTTP, or run longer than they should. Answers where a URL ends up and how many round trips that costs; it returns neither the body nor the headers of the destination (http_headers). Anonymous and rate-limited per IP; private and reserved address space is refused.
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 destination are not returned (http_headers covers headers). Anonymous, rate-limited per IP; private and reserved addresses are refused.
hsts_checkchangedtitle, description, annotationsCheck a domain's HTTP Strict Transport Security configuration: whether the header is present, its raw value, max-age in seconds, the includeSubDomains and preload flags, whether plain HTTP redirects to HTTPS, whether the configuration would qualify for the browser preload list, and warnings for values that make the header ineffective. Reports the policy the site advertises, not the certificate behind it (check_ssl) and not the full redirect chain (redirect_check). Anonymous and rate-limited per IP; private and reserved address space is refused.
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. Reports the advertised policy only; the certificate is check_ssl and the redirect chain redirect_check. Anonymous, rate-limited per IP; private and reserved addresses are refused.
http_headerschangedtitle, description, annotationsFetch a URL and return its HTTP response headers verbatim as a name/value map, with the status line and every redirect hop taken to get there. Use it to inspect caching, security and server headers as they are actually sent; the response body is never returned, so this says nothing about page content. For a plain up/down verdict use website_status, for the redirect chain alone redirect_check. Anonymous and rate-limited per IP; hosts resolving to private or reserved address space are refused.

asn_lookupread-only | 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 not identify the site owner. Private and reserved addresses have no announcing AS. ip_geolocation returns the same AS data plus country and PTR. Anonymous, rate-limited per IP. |
check_dnsread-only | 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 several. Reads records only and never connects to the host. Anonymous, rate-limited per IP. |
check_sslread-only | 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 (not an IP address) and an optional port (default 443). A single sample taken now; HTTP behaviour is covered by website_status and the HSTS policy by hsts_check. Anonymous, rate-limited per IP; private and reserved addresses are refused. |
dkim_checkread-only | 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 message's DKIM-Signature header (common provider values: google, selector1, default, k1). An unused selector returns found=false. Anonymous, rate-limited per IP. |
dmarc_checkread-only | 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 published policy, not whether real mail passes it; spf_check and dkim_check cover the mechanisms it aligns against. Anonymous, rate-limited per IP. |
dnsbl_checkread-only | 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 resolve one). Slow lists are skipped rather than awaited, so partial=true marks a provisional verdict. One call reflects only the current moment. Anonymous, with the strictest per-IP rate limit of the anonymous tools. |
dns_propagationread-only | 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 differ. check_dns is the cheaper call for a single reading of all record types. Anonymous, rate-limited per IP. |
domain_expiryread-only | 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 (check_ssl). tldSupported=false means the TLD has no queryable WHOIS server, not that the domain is unregistered. Anonymous, rate-limited per IP. |
hsts_checkread-only | 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. Reports the advertised policy only; the certificate is check_ssl and the redirect chain redirect_check. Anonymous, rate-limited per IP; private and reserved addresses are refused. |
http_headersread-only | 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 redirect chain alone. Anonymous, rate-limited per IP; private and reserved addresses are refused. |
ip_geolocationread-only | 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 addresses differs from where a visitor or business is located; it is not a street address. Private and reserved addresses have no answer. Anonymous, rate-limited per IP. |
mx_lookupread-only | 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 or test SMTP, and sender authorisation is covered by spf_check, dkim_check and dmarc_check. Anonymous, rate-limited per IP. |
ping_testread-only | 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 that drop ICMP still answer. website_status gives a one-shot verdict for a website. Anonymous, rate-limited per IP; private and reserved addresses are refused. |
port_checkread-only | 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 arrived, not that the port is certainly closed. TCP only, no UDP. Anonymous, rate-limited per IP; hosts resolving to private or reserved addresses are refused. |
redirect_checkread-only | 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 destination are not returned (http_headers covers headers). Anonymous, rate-limited per IP; private and reserved addresses are refused. |
response_timeread-only | 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 only: no browser runs, so JavaScript, assets and Core Web Vitals are not reflected. A snapshot, not a trend. Anonymous, rate-limited per IP; private and reserved addresses are refused. |
reverse_dnsread-only | 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 PTR is common and not a fault. Forward and reverse records need not agree, and this call does not check that they do. Anonymous, rate-limited per IP. |
spf_checkread-only | 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 returns found=false. Alignment and reporting belong to dmarc_check, signing keys to dkim_check. Anonymous, rate-limited per IP. |
website_statusread-only | 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 uptime; response_time, http_headers and redirect_check go deeper. Anonymous, rate-limited per IP; private and reserved addresses are refused. |
whoisread-only | 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 the TLD has no queryable WHOIS server, which differs from an unregistered domain (found=false). domain_expiry returns the expiry with the remaining days computed. Anonymous, rate-limited per IP. |
