Shodan tools 11
ip_lookupRetrieve comprehensive information about an IP address, including geolocation, operating system, open ports, running services (product, version, CPE), known vulnerabilities (CVEs), SSL certificates, hostnames, and cloud provider details if available. Returns service banners and HTTP server information when present. Optional history returns historical banners; minify omits banners.shodan_searchSearch Shodan's database of internet-connected devices. Returns detailed information about matching devices including services, vulnerabilities, and geographic distribution. Supports advanced search filters and returns facet statistics (default: by country). Costs 1 query credit when the query uses filters, plus 1 per page beyond the first. Use shodan_count (free) to get totals and facets without results.cve_lookupQuery detailed vulnerability information from Shodan's CVEDB. Returns comprehensive CVE details including CVSS scores (v4/v3/v2), EPSS probability and ranking, KEV status, proposed mitigations, ransomware associations, and affected products (CPEs).dns_lookupResolve domain names to IP addresses using Shodan's DNS service. Supports batch resolution of multiple hostnames in a single query. Returns IP addresses mapped to their corresponding hostnames.reverse_dns_lookupPerform reverse DNS lookups to find hostnames associated with IP addresses. Supports batch lookups of multiple IP addresses in a single query. Returns all known hostnames for each IP address, with clear indication when no hostnames are found.cpe_lookupSearch for Common Platform Enumeration (CPE) entries by product name in Shodan's CVEDB. Supports pagination and can return either full CPE details or just the total count. Useful for identifying specific versions and configurations of software and hardware.cves_by_productSearch for vulnerabilities affecting specific products or CPEs. Supports filtering by KEV status, sorting by EPSS score, date ranges, and pagination. Can search by product name or CPE 2.3 identifier. Returns detailed vulnerability information including severity scores and impact assessments.shodan_countGet the total number of Shodan results for a query, with optional facet breakdowns (e.g. by country, org, port). Free: does not consume query credits. Use search_filters to list valid filters and facets.domain_infoGet subdomains and DNS records for a domain from Shodan. Costs 1 query credit per lookup.api_infoShow the Shodan API plan, remaining query and scan credits, monitored IPs, and usage limits for the configured API key. Free: does not consume credits.search_filtersList the search filters and facets Shodan supports. Use this to build valid shodan_search and shodan_count queries and facets. Free: does not consume credits.
