# Validate project DSD structure and data

`GET /indicator_dsd/validate/{sid}`

Validates bound global DSD structure first. Data checks (column presence, codelist allow-lists, observation-key uniqueness) run only when structure is valid and published timeseries data exists in DuckDB. Always returns HTTP 200 with a report when the project exists (use `valid` and nested blocks, not only HTTP status).

## Path parameters

- `sid` string, required

## Response `200`

  - `data_validation` IndicatorDsdDataValidationBlock
    - `skipped` boolean — When true, data checks were not run (see reason)
    - `has_data` boolean
    - `source` string, nullable — e.g. published timeseries when data was checked
    - `valid` boolean, nullable — Null when data validation was skipped
    - `errors` string[]
    - `warnings` string[]
