Example response

A real response from this endpoint. Rows are returned under "data", and provenance is carried in the shape shown below — it is not identical across datasets, so read this page's rather than assuming another's.

Notes & limitations

  • The backend metadata exposes no grain or field list, so no field table is shown here and neither row counts nor a coverage window are guessed.
