name: Copernicus Marine
description: 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.

apis:
- name: Copernicus Marine Toolbox API
  description: The Copernicus Marine Toolbox provides the officially supported programmatic interface to the Copernicus Marine
    Data Store, available as both a Python library and CLI. Core operations include describe (browse the full product catalogue
    and retrieve dataset metadata), subset (extract data by variable, geographic bounding box, time range, and depth range
    in NetCDF, Zarr, CSV, or Parquet formats), get (download original production files with wildcard and regex filtering),
    open_dataset (lazy-load datasets remotely via xarray), and read_dataframe (load data directly into pandas). The service
    offers no quota on data volume or bandwidth. Authentication uses username and password stored in a credentials file or
    environment variables COPERNICUSMARINE_SERVICE_USERNAME and COPERNICUSMARINE_SERVICE_PASSWORD. A free Copernicus Marine
    account is required.

- name: Copernicus Marine WMTS API
  description: The Copernicus Marine Web Map Tile Service (WMTS) is an OGC-compliant REST API for visualizing ocean data as
    raster map tiles. It supports GetCapabilities to discover available datasets and layers, GetTile to retrieve cached image
    tiles in JPEG or PNG format, GetLegend to obtain dynamic map legends in SVG or JSON, and GetFeatureInfo to query pixel-level
    data values at specific geographic locations. Tiles are served in Web Mercator (EPSG:3857), WGS 84 (EPSG:4326), and polar
    projections. Temporal and depth dimensions are supported via TIME and ELEVATION parameters. The service is fully OGC WMTS
    1.0.0 compliant and INSPIRE conformant. No authentication is required for tile access.

- name: Copernicus Marine CSW Catalogue API
  description: The Copernicus Marine Catalogue Service for the Web (CSW) provides OGC-compliant metadata discovery over the
    full product catalogue. It supports GetCapabilities, DescribeRecord, GetRecords (search and filter catalogue entries),
    and GetRecordById (retrieve a specific product record by identifier). The service is based on CSW 2.0.2 and uses ISO 19115
    metadata records. No authentication or Copernicus Marine account is required, and there are no documented rate limits
    or quotas for the catalogue service.
