Get recommended Lightning Network peers for a given node. Returns nodes that are NOT currently peered with the specified node but would improve its centrality score if connected.

search_lightning_nodes_by_alias

Search for Lightning Network nodes by partial alias match. Returns nodes whose aliases contain the search term (case-insensitive).

domain_rdap

Queries the authoritative RDAP registry for a domain. Returns availability status (HTTP 404 = available), and for registered domains: registrar name, registration/expiration dates, nameservers, DNSSEC status, and domain status flags. Uses IANA bootstrap to find the correct RDAP server per TLD. Covers 590+ TLDs.

parse_hostname

Parse a hostname into its constituent parts using the Mozilla Public Suffix List (9700+ entries). Returns eTLD (effective TLD), registered domain, subdomain, labels, and depth. Handles multi-level eTLDs (co.uk, co.jp, com.au) and platform suffixes (github.io, herokuapp.com).

is_subdomain

Check whether a hostname is a subdomain (has labels beyond the registered domain). Uses the Mozilla Public Suffix List for accurate eTLD detection.

registered_domain

Extract the registered domain (eTLD+1) from a hostname. For example, www.mail.example.co.uk returns example.co.uk.

tld_info

Get information about a top-level domain or effective TLD. Returns whether it is in the Public Suffix List, how many sub-suffixes exist, and classification (ccTLD, gTLD, or infrastructure).

reverse_lookup_cname

Find hostnames that have a CNAME record pointing to the specified target. Useful for CDN and load balancer investigations.

historic_reverse_lookup_cname

Find hostnames that previously had a CNAME record pointing to the specified target but no longer do. Tracks CDN and infrastructure migrations.

ip_geolocation

Get geographic location data for an IP address: country, city, region, latitude, longitude, timezone.

ip_network

Get the containing network (BGP route), AS number, AS name, and route description for an IP address.

ip_to_asn

Lightweight lookup: get just the AS number and netblock for an IP address. Fastest way to map IP to ASN.

ip_blocklist_check

Check an IP address against IPsum, FireHOL, Tor exit node lists, C2 indicators, Roskomnadzor (Russia), and other threat intelligence feeds. Returns which lists the IP appears on and threat scores.

ip_threat_intel

Combined threat intelligence: DNSBL listings, IPsum score, FireHOL lists, bad ASN flag, Tor exit status. Comprehensive threat assessment for an IP address.

as_info

Get the name, organization, country, and description for an Autonomous System number. Lightweight version of as_whois.

as_prefixes

Get all IPv4 and IPv6 network prefixes (netblocks) announced by an Autonomous System. Returns BGP-visible routes.

domain_reputation

Get comprehensive domain reputation: Majestic rank, Tranco rank, HaGeZi blocklist status, Blackbook malware status, phishing database status, HSTS preload status, and disposable email detection.

domain_ranking

Get domain popularity rankings from five independent sources: Majestic Million (backlinks), Tranco top 1M (aggregated traffic), Cloudflare Radar (1.1.1.1 DNS query popularity), Cisco Umbrella (OpenDNS query popularity), and Chrome UX Report (real Chrome user traffic).

domain_blocklist_check

Check a domain against HaGeZi DNS blocklists, Steven Black unified hosts, Blackbook malware list, phishing databases, Roskomnadzor (Russia), and Citizen Lab censorship lists. Returns which lists the domain appears on.

domain_shared_ip

Find other domains hosted on the same IP address(es) as the target domain. Resolves the domain's A records, then performs reverse IP lookups for each.

domain_shared_ns

Find other domains using the same nameserver(s) as the target domain. Resolves the domain's NS records, then performs reverse NS lookups for each.

domain_shared_mx

Find other domains using the same mail server(s) as the target domain. Resolves the domain's MX records, then performs reverse MX lookups for each.

check_email

Verify an email address by connecting to its mail server via SMTP. Checks MX records, tests if the address is accepted (RCPT TO), detects catch-all domains, and reports TLS support. Results are RAM-cached for 1 hour.

ping

Check if the API is responding. Returns status and server timestamp.

No parameters.

lookup_bitcoin_transaction

Returns full transaction details: inputs with addresses and values, outputs with spent status, fee, size/weight, SegWit flag, and Lightning Network channel correlation. Supports both confirmed and mempool transactions.
