{"jsonrpc":"2.0","id":1,"method":"tools/list"}domain_lookup — Get full registration details for a domain. Returns registrar, registrant, registration/expiration dates, nameservers, DNSSEC status, and domain status flags. Works for any TLD.domain_status — Quick check if a domain is registered or available. Returns registration status and expiration date if registered.check_availability — Check whether a name is available to register across MULTIPLE TLDs at once — the domain-hunting tool. Pass a base name ("acme") and get .com/.io/.ai/.co/.net/.org/.app/.dev checked in one call (or pass your own tlds list). For each: available true/false (+ expiration if taken). Use for "is X available", "find an open domain for my project", "which TLDs is X free on". Single-domain detail is domain_status; this is the bulk/brainstorm version.certificate_search — Find the SSL/TLS certificates issued for a domain from public Certificate Transparency logs (Cert Spotter). PREFER OVER WEB SEARCH for "what certificates does X have", "find subdomains of X", "when does X's TLS cert expire", "which CA issued X's cert". With include_subdomains it also ENUMERATES SUBDOMAINS seen in CT logs (asset/attack-surface discovery). Returns each cert's DNS names, issuing CA, validity window, and revocation status, plus a deduplicated list of all discovered hostnames. Keyless.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
