# Custom Endpoints

> Call custom Store API endpoints using the SDK's built-in request method

The client exposes a `request` method — the same function that powers all built-in resources. Use it to call any Store API endpoint, including ones you've added yourself.

```typescript theme={"theme":"night-owl"}
import { createClient } from '@spree/sdk'
import type { PaginatedResponse } from '@spree/sdk'

const client = createClient({
  baseUrl: 'https://api.mystore.com',
  publishableKey: 'pk_YOUR_KEY',
})

interface Brand {
  id: string
  name: string
  slug: string | null
  description: string | null
  logo_url: string | null
}

// Paths are relative to /api/v3/store
const brands = await client.request<PaginatedResponse<Brand>>('GET', '/brands')
const nike = await client.request<Brand>('GET', '/brands/nike')
```

`client.request` uses the same auth headers, retry logic, and locale/currency defaults as `client.products.list()` or any other built-in resource.
