 ## Authentication
 
-All API endpoints require **either**:
+All **protected** endpoints require an API key as a path parameter `:key`.
 
-### 1. Bearer Token (JWT)
+Rules for `:key`:
 
-Send an `Authorization` header:
-
-```http
-Authorization: Bearer <JWT_TOKEN>
-```
-
-- Used for user-based access.
-- Token must be valid and not expired.
-
-### 2. API Key (for devices / machine-to-machine)
-
-Include an API key in the route as `:key` parameter:
-
-```text
-/api/.../:key/...
-```
+- Exactly 8 characters
+- Digits only (`^[0-9]{8}$`)

-### 2. Toggle Item Safe State
-
-Toggles `in_safe` between `0` and `1` for a given item.
-
-**Keep in mind that when you return a loan by code, the item states are automatically updated.**
+### 2.2 Toggle item safe state
 
 **POST** `/api/change-state/:key/:itemId`
 
-#### Path Parameters
+> You do not need this endpoint to set the states of the items when the items are taken out or returned. When you take or return a loan, the item states are set automatically by the loan endpoints. This endpoint is only for manually toggling the `inSafe` state of an item.

-#### Authentication
+- `:key` – API key (8 digits)
+- `:itemId` – numeric `id` of the item
 
-- Either Bearer token or `:key` API key.
+Handler in `api.route.js` calls `changeInSafeStateV2(itemId)`, which executes:
 
-#### Request Example
+```sql
+UPDATE items SET in_safe = NOT in_safe WHERE id = ?
+```

-## Notes
-
-- All responses are JSON.
-- Time fields like `take_date` and `returned_date` are in the format returned by MySQL (usually ISO-like strings).
-- `loaned_items_id` in the database is stored as a JSON array string (e.g. `"[1,2,3]"`) and is parsed internally; clients do not interact with this field directly via current endpoints.
+- `200 OK` – operation succeeded
+- `400 Bad Request` – invalid `state` parameter
+- `401 Unauthorized` – invalid/missing API key
+- `404 Not Found` – loan not found
+- `500 Internal Server Error` – database / server failure or `success: false` from DB layer
