-This code defines a `Book` model using Pydantic's `BaseModel`, and a `BookSchema` schema for the request body. It creates an in-memory list `books` to store the book data.
-
-The `@router.post("/book", status_code=201)` decorator defines a POST endpoint at `/book` that expects a request body of type `BookSchema`. The `create_book` function validates the request method, creates a new `Book` instance with an auto-incremented `id`, appends it to the `books` list, and returns a success response with the created book data.
-
-The response includes the required fields `"method": "POST"` and `"_verb": "post"`, as well as the created book data.
-
-Note: This is a simple example using an in-memory list for data storage. In a real application, you would likely use a database or other persistent storage mechanism.

+This code defines a `BookModel` using Pydantic, which includes validation rules for each field. The `create_book` endpoint accepts a `BookModel` instance in the request body, assigns a new `id`, appends it to the `books` list, and returns the created book object along with the HTTP method metadata.
