How do you handle request bodies in FastAPI?

Re-explain

Request bodies are handled using Pydantic models:

from pydantic import BaseModel
from fastapi import FastAPI

app = FastAPI()

class Item(BaseModel):
    name: str
    price: float
    is_offer: bool = False

@app.post("/items/")
def create_item(item: Item):
    return {"item_name": item.name, "item_price": item.price}

FastAPI automatically validates the request body against the Pydantic model and provides detailed error messages for invalid data.
