  description: >-
    Versioned climate data with preserved meaning. Discover → inspect → resolve
    → query. Small published-data queries return values directly, with explicit
    units, spatial support, missingness and provenance. Public demo endpoints
    require no credentials. Paid acquisition is not enabled; consult
    capabilities before planning a workflow.
