# Suggest entity classifications

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

Default classification discovery path for enrichment agents. Returns ranked embedding-derived tag and standardized-code suggestions; empty array means no embedding neighbors. Create joins with the entity classifications create endpoint.

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

- `limit` (integer, optional) — Maximum suggestions to return; capped by the service.

## Response

### 200

OK

- `list of object`
  - `alreadyJoined` (boolean, required) — True when the entity already has a current or historical matching join.
  - `classification` (object or object, required) — Suggested writable editorial tag or standardized classification code candidate.
    - EntityTag
      - `creatable` (boolean, required)
      - `name` (string, required) — Display name. Capped to the standardized taxonomy storage limit because this shared read contract covers NAICS/SIC/ISIC-style classification labels as well as editorial tags.
      - `writable` (boolean, required)
      - `creatable` (boolean, required) — Whether this bucket permits creating missing values by type plus name.
      - `id` (integer, required) — Classification tag registry id from res_type_ref; use as EntityClassificationMutation.tagId.
      - `name` (string, required) — Name
      - `type` (string, required) — Canonical tag classification type
      - `writable` (boolean, required) — Whether this existing tag can be joined through tagId.
      - `isCurrent` (boolean, optional, nullable)
      - `isPrimary` (boolean, optional, nullable)
      - `bucket` (string, optional, nullable) — Canonical entity-classification bucket key. Use this as EntityClassificationMutation.type when creating by type plus name; `type` remains the registry wire value for tag search and catalog round-trips.
      - `classificationId` (integer, optional, nullable) — Entity classification join row id for update/delete; present on entity classification responses and null on discovery responses.
      - `createdAt` (datetime, optional, nullable) — Registry tag creation timestamp, not the entity join timestamp.
      - `isCurrent` (boolean, optional, nullable) — Current-state flag for this context: registry active flag in discovery, entity join current flag in entity-classification responses.
      - `isPrimary` (boolean, optional, nullable) — Entity join primary flag within its bucket; null on catalog/tag discovery.
      - `slug` (string, optional, nullable) — Slug
      - `updatedAt` (datetime, optional, nullable) — Registry tag update timestamp; join updates return isCurrent/isPrimary but no join updatedAt.
    - StandardizedClassification
      - `creatable` (boolean, required)
      - `name` (string, required) — Display name. Capped to the standardized taxonomy storage limit because this shared read contract covers NAICS/SIC/ISIC-style classification labels as well as editorial tags.
      - `writable` (boolean, required)
      - `category` (string, required) — Standardized category token.
      - `creatable` (boolean, required) — Standardized taxonomy rows are join-existing-only.
      - `id` (integer, required) — Standardized classification registry id from res_classification_ref; use as EntityClassificationMutation.classificationId.
      - `name` (string, required) — Name
      - `writable` (boolean, required) — Existing standardized rows can be joined through classificationId.
      - `isCurrent` (boolean, optional, nullable)
      - `isPrimary` (boolean, optional, nullable)
      - `code` (integer, optional, nullable) — Standardized classification code when present.
      - `createdAt` (datetime, optional, nullable) — Registry row creation timestamp.
      - `entityClassificationId` (integer, optional, nullable) — Entity classification join row id for update/delete; present on entity classification responses and null on discovery responses.
      - `isCurrent` (boolean, optional, nullable) — Standardized reference rows are current by definition.
      - `isPrimary` (boolean, optional, nullable) — Entity join primary flag within this standardized category.
      - `level` (integer, optional, nullable) — Hierarchy level when present.
      - `updatedAt` (datetime, optional, nullable) — Registry row update timestamp.
  - `creatable` (boolean, required) — Whether a missing editorial tag value may be created with type plus name instead of tagId.
  - `rank` (integer, required) — One-based rank within this suggestion response.
  - `score` (double, required) — Composite embedding similarity score; larger values rank higher.
  - `writable` (boolean, required) — Whether this suggestion can be joined through the classification mutation endpoint.
