# Search classifications

GET https://api.aventure.vc/v1/classifications/search

Returns a paginated list of editorial tags and standardized classifications. Filter by category using any bucket or standardized category spelling listed by the catalog. Results expose writable/creatable policy so callers know whether to join by id or create by type plus name. Sorting is not supported — sort returns 422.

Reference: https://docs.aventure.vc/api-reference/a-venture-api/classification-tags/search-classifications

## Authentication

- `X-Client-Secret` header (required) — Client secret for read-only service-to-service access (no writes)

## Request

### Query parameters

- `category` (string, optional) — Classification bucket or standardized category. Case- and punctuation-insensitive.
- `q` (string, optional) — Case-insensitive name substring filter (e.g. 'enterprise').
- `page` (integer, optional, default: 0) — Zero-based page index (0..N)
- `size` (integer, optional, default: 25) — The size of the page to be returned
- `sort` (list of string, optional) — Sorting criteria in the format: property,(asc|desc). Default sort order is ascending. Multiple sort criteria are supported.

## Response

### 200

OK

- `content` (list of object or object, optional)
  - 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.
- `empty` (boolean, optional)
- `first` (boolean, optional)
- `last` (boolean, optional)
- `number` (integer, optional)
- `numberOfElements` (integer, optional)
- `pageable` (object, optional)
  - `offset` (long, optional)
  - `pageNumber` (integer, optional)
  - `pageSize` (integer, optional)
  - `paged` (boolean, optional)
  - `sort` (object, optional)
    - `empty` (boolean, optional)
    - `sorted` (boolean, optional)
    - `unsorted` (boolean, optional)
  - `unpaged` (boolean, optional)
- `size` (integer, optional)
- `sort` (object, optional)
  - `empty` (boolean, optional)
  - `sorted` (boolean, optional)
  - `unsorted` (boolean, optional)
- `totalElements` (long, optional)
- `totalPages` (integer, optional)
