OSCAR/Surface REST API

The OSCAR/Surface REST API provides programmatic access to the WMO Observing Systems Capability Analysis and Review tool for surface-based stations. The public GET endpoints enable search and retrieval of station metadata records in JSON format covering WIGOS station identifiers, station locations, observation variables, and operational status. The search station endpoint supports pagination with up to 50,000 station records per query. Authentication tokens are required for write (POST/XML upload) operations but not for read access.
