# Get entity classification joins

GET https://api.aventure.vc/v1/entities/{entityId}/classifications

Returns joins grouped by bucket. The default view includes current rows; includeInactive=true adds historical rows and requires read auth.

Reference: https://docs.aventure.vc/api-reference/a-venture-api/entity-classifications-canonical/get-entity-classifications

## Authentication

- `Authorization` header (bearer token, required) — User bearer token: Supabase or Clerk session JWT, Clerk OAuth access token, or Clerk personal API key
- `X-API-Key` header (required) — Admin API key for system-to-system write operations
- `X-Client-Secret` header (required) — Client secret for read-only service-to-service access (no writes)

## Request

### Path parameters

- `entityId` (string, required) — Canonical entity UUID

### Query parameters

- `includeInactive` (boolean, optional, default: false) — Include inactive/historical entity classification join rows; default false returns only current joins.

## Response

### 200

OK

- `geoLocationExposure` (list of object, optional, default: []) — Geographic markets where the entity earns revenue and serves customers (e.g. North America, EMEA, APAC).
