# Get the bounded Wikidata company metadata projection

`GET /api/v1/company/{slug}/wikidata`

Read only the CC0 structured subset in company_integrations_public_v1 after company_public_v2 admission: Q-id, entity URL, ticker and inception. Labels, logos, websites, CEO text, LEI and Wikipedia content are excluded. Empty coverage is not proof that the company is absent upstream.

## Path parameters

- `slug` string, required

## Headers

- `If-None-Match` string

## Response `200`

Wikidata metadata projection or its documented empty shape

- CompanyWikidataResponse — Generation-bound minimized Wikidata company view. Empty describes the bounded projection only.
  - `projection_status` 'available', required
  - `projection` CompanyIntegrationProjection, required
    - `name` 'company_integrations_public_v1', required
    - `schema_version` '1.3', required
    - `builder_version` '1.4.0', required
    - `generation` string, required
  - `slug` string, required
  - `cif` string, required
  - `complete_bounded_projection` true, required
  - `coverage_status` 'available' | 'empty', required
  - `source_metadata` CompanyIntegrationSourceMetadata, required — Projection-bound legal metadata plus the exact governed acquisition boundary for a company integration source.
    - `slug` 'bdns' | 'cnmv' | 'ted_eu' | 'wikidata', required

    - `acquisition_coverage` CompanyIntegrationAcquisitionCoverage, required — Attested acquisition boundary for one governed source package. Completeness applies only to this exact bounded scope; complete_history_claimed and source_snapshot_claimed are always false, so this metadata never asserts complete historical or upstream snapshot coverage.

      - `declared_scope_complete` true, required — All partitions declared by this bounded acquisition scope were captured; this is not a complete-history claim.

      - `source_fragment_sha256` string, required
      - `source_authority_binding_sha256` string, required
      - `coverage_sha256` string, required — Digest of the producer-declared bounded coverage object; it is integrity evidence, not proof of complete history.
