+
+This code defines a `Book` model using Pydantic's `BaseModel`, and an in-memory `books` list to store the book data. The `@router.post("/books")` endpoint accepts a `Book` object in the request body, assigns it a new `id`, appends it to the `books` list, and returns a success response with the created book object and metadata about the HTTP method used.
+
+The code also includes a check for the HTTP method, raising a `405 Method Not Allowed` exception if the request method is not `POST`. The response includes the `"method": "POST"` and `"_verb": "post"` fields as required.
+
+Note that this is a basic example, and in a real-world application, you would likely use a database instead of an in-memory list, and implement additional features such as data validation, error handling, and authentication/authorization.
