+    # Specific Price API
+
+    Endpoints for managing specific price rules (price reductions).
+
+    ## Scopes
+
+    Specific prices can be **global** or **scoped**:
+
+    - **Global**: If all scope arrays (`product_ids`, `category_ids`, `product_attribute_ids`, `country_ids`, `customer_ids`) are empty, the price reduction applies to everything.
+
+    - **Scoped**: If ANY scope array has values, the price reduction applies only when ANY condition matches (UNION logic).
+
+    ### Scope Fields
+
+    | Field | Type | Description |
+    |-------|------|-------------|
+    | `product_ids` | uint[] | Specific products |
+    | `category_ids` | uint[] | Products in categories |
+    | `product_attribute_ids` | uint[] | Product variants (e.g., size, color) |
+    | `country_ids` | uint[] | Customers in countries |
+    | `customer_ids` | uint[] | Specific customers |
+
+    ### Examples
+
+    **Global** (applies to all products):
+    ```json
+    {
+      "name": "Global Sale",
+      "reduction_type": "percentage",
+      "percentage_reduction": 10,
+      "from_quantity": 1
+    }
+    ```
+
+    **Scoped to specific products**:
+    ```json
+    {
+      "name": "Product Sale",
+      "reduction_type": "percentage",
+      "percentage_reduction": 20,
+      "product_ids": [1, 2, 3]
+    }
+    ```
+
+    **Scoped to category + country**:
+    ```json
+    {
+      "name": "Category Country Sale",
+      "reduction_type": "amount",
+      "price": 9.99,
+      "category_ids": [5],
+      "country_ids": [1]
+    }
+    ```
+
+    ## Reduction Types
+
+    - `percentage`: Requires `percentage_reduction` (e.g., 10.5 = 10.5% off)
+    - `amount`: Requires `price` (fixed price after reduction)
+
+    ## Validation
+
+    - `reduction_type` is required and must be "percentage" or "amount"
+    - If `reduction_type` is "percentage", then `percentage_reduction` is required
+    - If `reduction_type` is "amount", then `price` is required
