validate_targetFree. Check that a domain or URL is well-formed and get the normalized hostname, before calling a paid check. Offline: no network request, no payment. Rejects IP addresses, single-label names and URLs with credentials.
pricingFree. Return the price of every paid tool, the payment network (Base) and the receiving address, so you can budget before calling. No input, no network request, no payment.
check_certCheck the TLS certificate of one hostname: issuer, validity dates, days left, % of lifetime used, renewal cadence and a renewal-stall flag, plus a live HTTPS pass/fail probe. Use it when you only need certificate health; use site_health for cert + DNS + expiry together, or domai…
check_dnsLook up the live DNS of a domain: NS, A/AAAA/CNAME, MX, SPF, DMARC, CAA (climbing to the parent zone) and DNSSEC status, with plain-English findings. Use it for a DNS inventory or to debug resolution; use check_email_auth for a deeper SPF/DMARC/DKIM/MTA-STS review. Queries Cloud…
check_domain_expiryCheck when a domain registration expires: registrar, registered and expiry dates, days left, EPP status codes and nameservers, from the registry's RDAP server. Use it for renewal risk on the registered domain (not the certificate; use check_cert for that). Some TLDs publish no R…
site_healthRun check_cert, check_dns and check_domain_expiry together and return their raw results plus a short summary, the renewal-stall flag and the Let's Encrypt 64-day certificate note (from 2027-02-10). Use it for a full data dump in one call; use domain_grade if you want a single sc…
check_email_authReview the email authentication setup of a domain: SPF validity and DNS-lookup count (limit 10), DMARC policy, pct and reporting, DKIM on common selector names, MTA-STS mode, TLS-RPT and BIMI, with a rough 0-100 score and plain-English fixes. Use it before sending mail from a do…
check_security_headersCheck the HTTP security headers of a website with one live HTTPS GET: redirect chain (up to 5 hops), final status, HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and COOP, with a simple A-F header grade and findings. Use it for web-harden…
domain_gradeGrade a domain's security posture A-F in one call, for vendor-risk or due-diligence checks. Runs the TLS, DNS (DNSSEC, CAA), registration-expiry, email-auth and HTTP-header checks and returns one letter, a 0-100 score, points per category (TLS 25, email 25, headers 20, DNS 15, r…
full_site_auditFull site audit report for one domain, for client reports, vendor reviews or a pre-launch check. Runs every check (TLS from CT logs + live probe, DNS/DNSSEC/CAA, registration expiry and transfer lock, SPF/DMARC/DKIM/MTA-STS, security headers) plus HTTP->HTTPS redirect, www/apex…
threat_checkIs this domain known-bad? Resolves the hostname (A/AAAA), matches the name, its parent domains and resolved IPv4 against ThreatCluster's high-confidence 30-day IOC feed (cached, refreshed about hourly), and looks up ransomware leak-site claims naming the domain (commercially reu…
bulk_threat_checkCheck up to 100 domains or IPv4 addresses at once against ThreatCluster's high-confidence 30-day IOC feed; each domain is resolved and its IPv4 matched too. IOC only (no ransomware-claim lookups; use threat_check for one domain). Stale feed returns an error and is not charged. C…
expiry_batchCertificate and domain-registration expiry for 2 to 5 domains in one call: days left, expiry dates and an ok/warn/expired status per domain, plus the soonest date overall. Certificate dates come from CT logs, registration dates from RDAP. Partial results if some lookups fail; if…
watch_statusFree. Status of a paid domain watch (created with HTTP POST /v1/watch): items, expiry, last check, current DNS/IOC/claim state, last webhook delivery. Needs the webhook_secret from creation.
