+# Rotate PDF Endpoint
+
+This API endpoint allows you to rotate a specific page of a PDF file. It uses the PyPDF2 library to perform the rotation.
+
+## API Endpoint
+
+### Endpoint URL
+
+```
+POST /rotate_pdf
+```
+
+### Request Parameters
+
+- `details`: An object containing the rotation details.
+  - `page` (integer): The page number to rotate.
+  - `degree` (integer): The rotation angle in degrees.
+
+- `file`: The PDF file to rotate.
+
+### Response
+
+The API response will include the following:
+
+- `response` (string): A message indicating whether the PDF rotation was successful.
+
+- `path` (string): The path of the rotated PDF file.
+
+### Implementation Steps
+
+1. Read the input rotation details and the PDF file.
+
+2. Use the PyPDF2 library to open the PDF file.
+
+3. Create a new PDF writer object.
+
+4. Get the specified page from the PDF.
+
+5. Rotate the page using the `rotateClockwise` method and the specified rotation degree.
+
+6. Add the rotated page to the PDF writer.
+
+7. Write the output PDF file using the PDF writer.
+
+8. Close the output file.
+
+9. Return the API response with the message indicating the success of the rotation and the path of the rotated PDF file.
+
+That's it! With these implementation steps, you can rotate a specific page of a PDF file using this API endpoint.
