#ports

See what any host exposes to the internet — as an API over Shodan's free InternetDB. Give it an IPv4/IPv6 address (or a hostname, which is resolved to its IP) and get that host's attack surface: the open ports (annotated with common service names), the products and technologies detected on it (CPEs), its reverse hostnames, Shodan's classification tags, and the known vulnerabilities (CVE identifiers) observed on its services. A dedicated vulnerabilities view returns just the CVEs and whether the host appears vulnerable. It is fast, requires no key, and is built for security, asset-discovery, external attack-surface monitoring and reconnaissance workflows. A network-exposure / attack-surface resource — distinct from IP geolocation (where an address is), the IANA port registry (what a port number means) and CVE databases (what a vulnerability is). Data from Shodan InternetDB (free / non-commercial use).

The UN/LOCODE registry (United Nations Code for Trade and Transport Locations) as an API — 116,000+ ports, airports, rail and road terminals and trade points across 249 countries. Resolve any 5-character code (e.g. USNYC → New York; DEHAM → Hamburg; NLRTM → Rotterdam) to its name, country, subdivision, transport functions (port, rail, road, airport, postal, …), IATA code and coordinates; search locations by name with country and function filters; or list every location in a country. UN/LOCODE is the standard used in shipping, logistics, customs and EDI. Ideal for supply-chain, freight, trade-compliance and logistics software.

The NGA World Port Index (WPI / Pub 150) as an API — 3,800+ maritime ports across 195 countries. Look up any port by its WPI number (e.g. 31140 → Rotterdam) or UN/LOCODE (e.g. NLRTM); search by name, country, harbor size or water body; or find every port within a radius of any coordinate (great-circle distance). Each record carries the UN/LOCODE, country, coordinates, harbor size and type, channel/anchorage/pier depths, maximum vessel length and draft, plus facility flags (container, oil/LNG terminal, ro-ro, dry dock, …). Ideal for shipping, logistics, maritime and supply-chain tools.

Search a database of 17,000+ seaports worldwide from UN/LOCODE. Find ports by name and country, look one up by its UN/LOCODE, or find all ports near a coordinate (radius search). Each record includes the UN/LOCODE, coordinates, country and connected transport modes (rail, road, airport) — ideal for shipping, freight, supply-chain and logistics applications.
