+  ## Auto-Link Unlinked Books
+  
+    Automatically links unlinked books to media items based on title and author matching with a configurable confidence threshold.
+  
+    **Method:** POST
+  
+    **Endpoint:** /sync/auto-link-books
+  
+    **Authentication:** Bearer token
+  
+    **Request Body:**
+    - `confidence_threshold` (number, optional): Minimum confidence score for auto-linking (0-1, default: 0.8)
+    - `limit` (number, optional): Maximum number of books to auto-link (default: 50)
+  
+    **Response:**
+    - `results` (array): Results for each auto-link attempt
+    - `total` (number): Total number of books processed
+    - `success` (number): Number of successful links
+    - `failed` (number): Number of failed links
+  
+    **Status Codes:**
+    - 200: Success
+    - 400: Invalid request data

+  
+    **Note:** Higher confidence thresholds produce fewer but more accurate matches. Consider the tradeoff between automation and accuracy.
