46 tools

• latest_lightning_channels

  Returns the most recently opened Lightning Network channels, sorted by open time descending.

• ip_reputation

  Check an IP address reputation against 100+ real-time blocklists (DNSBLs). Returns listing status, threat categories, AS info, and blocklist details.

• lookup_dns

  Lookup DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA) for a given hostname. Also returns domain reputation info (Majestic, Tranco rankings, blocklist status).

• reverse_lookup_dns_records

  Find hostnames that use a specific DNS record value. Query which hostnames point to an IP address, use a particular nameserver, or reference any DNS value. For example: 'which hostnames point to 1.2.3.4?' or 'which hostnames use chris.ns.cloudflare.com as their nameserver?'

• reverse_lookup_mx

  Find hostnames that use a specific mail server. For example: which hostnames use aspmx.l.google.com as their mail server?

• reverse_lookup_ns

  Find hostnames that use a specific nameserver. For example: which hostnames use chris.ns.cloudflare.com as their nameserver?

• reverse_lookup_ip

  Find hostnames that point to a specific IP address (IPv4 or IPv6). Searches both A and AAAA records. For example: which hostnames point to 1.2.3.4?

• historic_reverse_lookup_ns

  Find hostnames that *previously* used a specific nameserver but no longer do. Tracks infrastructure migrations and past delegation relationships.

• historic_reverse_lookup_mx

  Find hostnames that *previously* used a specific mail server but no longer do. Tracks email provider migrations and past MX relationships.

• historic_reverse_lookup_ip

  Find hostnames that *previously* pointed to a specific IP address but no longer do. Tracks hosting migrations and past IP relationships. Searches both A and AAAA records.

• lookup_mac

  Look up the manufacturer/vendor of a network device by its MAC address. Uses the official IEEE OUI (Organizationally Unique Identifier) database with ~30K entries.

• lookup_as_whois

  Lookup WHOIS information for an Autonomous System (AS) number from the RADB routing database. Returns routing policy, network information, and administrative contacts.

• lookup_lightning_node

  Lookup a Lightning Network node by public key. Returns node alias, peer count, channel count, and centrality ranking.

• lookup_lightning_channel

  Lookup a Lightning channel by channel ID. Supports numeric, block x txn x vout, or block:txn:vout formats.

• lookup_lightning_channels_per_node

  Lookup all Lightning Network channels for a given node by public key.

• get_recommended_lightning_peers

  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 s

• 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.

• dns_differential

  Resolve a domain through filtered public DNS resolvers and their unfiltered controls to detect provider threat-feed blocks.

• 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.

Security scan

• No findings. We scan names, descriptions and tool definitions for hidden instructions and other prompt-injection patterns.
