  title: OECD SDMX REST Data Structure API
  description: 'The OECD provides programmatic access to its statistical data through a

    public SDMX REST API. Both SDMX REST v1.5.0 and v2.0.0 paths are exposed.

    Endpoints return data and structural metadata (dataflows, code lists,

    concept schemes, agencies) about OECD datasets. The API is free of charge

    and offered under the OECD Terms and Conditions; no authentication is

    required for public data.
