# Seaports API
> 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.

## Authentication
