> Understand the hierarchy of verticales and categories in Lokki

The Lokki API organizes rental items into a two-level hierarchy: **Verticales** and **Categories**. This structure helps users find products and services efficiently across different rental sectors.

## Core Concepts

### Verticales

Verticales represent the top-level sectors in the Lokki ecosystem. Each verticale defines a broad domain of rental activity.

**Examples of Verticales:**

* `BIKE`: All types of bicycles.
* `CAR`: Cars, vans, and other road vehicles.
* `SKI`: Winter sports equipment.
* `BOAT`: Marine and watercraft.

### Categories

Categories provide a more granular classification within each Verticale.

**Examples of Categories:**

* Under `BIKE`: `Mountain Bike`, `Road Bike`, `City Bike`, `Electric Bike`.
* Under `CAR`: `Convertible`, `SUV`, `Compact`, `Utility`.

## Data Structure

### Verticale (`VerticaleExternalDto`)

A Verticale object contains its unique identifier and localized descriptive information.

* `id`: The machine-readable identifier (e.g., `BIKE`, `CAR`).
* `infos`: Contains the `name` and `description` of the verticale, localized based on the `lang` parameter.

### Category (`CategoryExternalDto`)

A Category object provides details about a specific sub-sector.

* `id`: Unique identifier for the category.
* `name`: Localized name of the category.
* `verticale`: The Verticale ID this category belongs to.

Once you have identified the appropriate Verticale or Category IDs, you can use them to filter stores and store items.
