+Sure, here's an example of a FastAPI endpoint that adds countries to the database using SQLAlchemy models and Pydantic schemas:
+
+```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.countries_model import *
+from app.api.schemas.countries_schema import *
+from app.api.dependencies.countries_deps import *
+# SQLAlchemy setup
+Base = declarative_base()
+engine = create_engine('sqlite:///countries.db')
+SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=engine)
+
+# Database model
+
+app = FastAPI()
+
+@app.post('/countries', response_model=List[CountryCreate])
+def create_countries(countries: List[CountryCreate], db: Session = Depends(get_db)):
+    db_countries = []
+    for country_data in countries:
+        country = Country(name=country_data.name, capital=country_data.capital)
+        db.add(country)
+        db_countries.append(country_data)
+    db.commit()
+    return db_countries
+```
+
+Here's a breakdown of the code:
+
+1. We define a SQLAlchemy database model `Country` with fields `id`, `name`, and `capital`.
+2. We create a Pydantic schema `CountryCreate` to validate the incoming data for creating new countries.
+3. We define a dependency function `get_db` to provide a database session for each request.
+4. We create a FastAPI app instance.
+5. We define the `/countries` endpoint with the `POST` method and `response_model` set to a list of `CountryCreate` objects.
+6. In the endpoint function `create_countries`, we iterate over the list of `CountryCreate` objects received in the request body.
+7. For each `CountryCreate` object, we create a new `Country` instance and add it to the database session.
+8. We commit the changes to the database and return the list of `CountryCreate` objects.
+
+To use this endpoint, you can send a `POST` request to `/countries` with a JSON payload containing a list of country objects, like this:
+
+```json
+[
+  {
+    "name": "United States",
+    "capital": "Washington, D.C."
+  },
+  {
+    "name": "Canada",
+    "capital": "Ottawa"
+  }
+]
+```
+
+This will create new entries in the `countries` table of the database with the provided names and capitals.
