+Sure, here's an example of a FastAPI endpoint that saves cities in France to the database using SQLAlchemy and Pydantic:
+
+```python
+from typing import List
+from fastapi import FastAPI, Depends
+from sqlalchemy import Column, Integer, String
+from sqlalchemy.orm import Session
+from sqlalchemy.ext.declarative import declarative_base
+from pydantic import BaseModel
+
+from app.api.models.cities_model import *
+from app.api.schemas.cities_schema import *
+from app.api.dependencies.cities_deps import *
+# SQLAlchemy setup
+Base = declarative_base()
+engine = create_engine('sqlite:///cities.db')
+SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=engine)
+
+# SQLAlchemy model
+
+# FastAPI app
+app = FastAPI()
+
+# Endpoint for saving cities in France
+@app.post('/cities', response_model=List[CityCreate])
+def create_cities(cities: List[CityCreate], db: Session = Depends(get_db)):
+    db_cities = [City(name=city.name, department=city.department) for city in cities]
+    db.add_all(db_cities)
+    db.commit()
+    return cities
+```
+
+Here's a breakdown of the code:
+
+1. We define SQLAlchemy models and Pydantic schemas for representing cities.
+2. We set up a SQLite database using SQLAlchemy's `create_engine` function.
+3. We create a dependency function `get_db` that provides a database session for each request.
+4. We define a FastAPI app instance.
+5. We create a POST endpoint `/cities` that accepts a list of `CityCreate` objects in the request body.
+6. Inside the endpoint function, we create SQLAlchemy `City` objects from the `CityCreate` objects.
+7. We add the `City` objects to the database session and commit the changes.
+8. Finally, we return the list of `CityCreate` objects as the response.
+
+To use this endpoint, you can send a POST request to `/cities` with a JSON payload containing a list of cities, like this:
+
+```json
+[
+  {
+    "name": "Paris",
+    "department": "Paris"
+  },
+  {
+    "name": "Marseille",
+    "department": "Bouches-du-Rhône"
+  },
+  {
+    "name": "Lyon",
+    "department": "Rhône"
+  }
+]
+```
+
+This will create new rows in the `cities` table of the SQLite database for each city in the request payload.
