**APIs profiled:** 3

The EU Copernicus Marine Environment Monitoring Service (CMEMS), operated by Mercator Ocean International, provides free and open access to authoritative information on the state of the global ocean and European regional seas. The service delivers ocean physical and biogeochemical data through multiple APIs covering temperature, salinity, sea level, currents, sea ice, and marine ecosystem variables from satellite observations, in situ measurements, and numerical model reanalysis and forecast products. Data can be accessed programmatically via the Copernicus Marine Toolbox (Python API and CLI), the OGC-compliant Web Map Tile Service (WMTS) for visualization, and the Catalogue Service for the Web (CSW) for product discovery. All services require a free Copernicus Marine account, except the CSW which is fully open, and there are no data volume quotas or download limits.
