+Sure, here's an example of a FastAPI endpoint that returns a list of books from a database using SQLAlchemy and Pydantic:
+
+```python
+from typing import List
+from fastapi import APIRouter, Depends
+from sqlalchemy.orm import Session
+from database import get_db
+from models import Book
+from schemas import BookSchema
+
+router = APIRouter()
+
+# SQLAlchemy model
+
+    class Config:
+        orm_mode = True
+
+@router.get("/books", response_model=List[BookSchema])
+
+Here's a breakdown of the code:
+
+1. We import the necessary modules and classes from FastAPI, SQLAlchemy, and Pydantic.
+2. We define the `Book` SQLAlchemy model with columns for `id`, `title`, `author`, `description`, and `rating`.
+3. We define the `BookSchema` Pydantic model, which will be used for data validation and serialization/deserialization.
+4. We create a `router` instance from `APIRouter`.
+5. We define the `/books` endpoint using the `@router.get` decorator, and specify the `response_model` as a list of `BookSchema` objects.
+6. Inside the `get_books` function, we use the `db` dependency (provided by `get_db`) to query the database and retrieve all books using `db.query(Book).all()`.
+7. The retrieved books are returned as the response.
+
+To use this endpoint, you would need to include the `router` in your FastAPI application, like this:
+
+```python
+from fastapi import FastAPI
+from routers import books
+
+from app.api.models.books_model import *
+from app.api.schemas.books_schema import *
+from app.api.dependencies.books_deps import *
+app = FastAPI()
+app.include_router(books.router)
+```
+
+Then, you can access the `/books` endpoint using a GET request, and it will return a JSON response containing a list of books from the database.
+
+Note that you'll also need to set up a database connection and define the `get_db` dependency function, which is not shown in this example code.
