🔧 Available Tools (45)

• 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 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.
• 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.
• lookup_bitcoin_address: Returns address balance, total received/sent, transaction counts, address type (P2PKH, P2SH, P2WPKH, P2TR), first/last seen block, and ransomware/abuse flags. Supports all Bitcoin address formats.
• lookup_bitcoin_block: Returns block header (hash, timestamp, version, merkle root, difficulty, nonce), transaction count, and list of transaction IDs. Supports lookup by block height.
• bitcoin_address_transactions: Returns a paginated list of transactions involving a Bitcoin address. Filter by direction: received (incoming funds), sent (outgoing funds), or all. Returns up to 100 transactions per call, sorted by block height descending (most recent first).
• bitcoin_transaction_spends: For a given transaction, returns which subsequent transactions consumed its outputs. Useful for UTXO tracking and chain analysis. Shows the spending txid for each output.
• bitcoin_blockchain_stats: Returns cumulative blockchain metrics over a configurable block range. Available metrics include: txs, fees, segwittx, inputs, outputs, insats, outsats, btcusd, volusd, unspentoutputs, fullyspent, unspentsats, addresses, satoshiblocks, clnopen, clnclose, satlnopen, satlnclose, basereward, blockreward, batched, rbf, version2tx, lowestfee, and more.
