The open-data ports reference (NGA World Port Index) — ~3,800 ports with coordinates, UN/LOCODE, harbor size/type/use, max vessel draft, channel depth, and container / oil / LNG terminal facilities. Filter by country, harbor size, terminal type, name, or proximity to a point / GEM energy asset. This is reference data (no date window). Requires a plan with Maritime intelligence access (can_use_maritime) — the Corporate & Supply Chain plan and above.
When a proximity center is set (near, near_gem_id), each row carries distance_km and results sort nearest-first. Standard envelope: { success, data, pagination, applied_filters }.
Query parameters
Case-insensitive match on port name, alternate name, or UN/LOCODE.
Country filter on ports. Accepts a country name, ISO-2, or ISO-3 (e.g. Netherlands, NL, NLD) via the shared resolveCountryInput layer; an unresolvable value returns 400 INVALID_COUNTRY.
Minimum harbor size (inclusive of larger sizes).
true → only ports with an LNG terminal.
true → only ports with an oil terminal.
Point 'lat,lon' for a radius search; combine with radius_km (default 100). Results carry distance_km, sorted nearest-first.
GEM energy-asset gem_id — returns ports within radius_km of that LNG terminal / platform / port (cross-source join).
Radius in km for near / near_gem_id. Default 100; clamped 1–2000.
Bounding box filter: minLon,minLat,maxLon,maxLat (lon-first, e.g. -6,35,5,44).
Rows per page (1–500).
Pagination cursor (offset) from a prior response's next_cursor.
Response
A page of ports. Each row: port_id, name, alt_name, unlocode, country (ISO-3), country_name, region, water_body, lat, lon, harbor_size, harbor_type, harbor_use, max_vessel_draft_m, channel_depth_m, lng_terminal / oil_terminal / container booleans, and distance_km (only when a proximity center is set).
