# Recipes

We've written some recipes that demonstrate how to solve common problems with OkHttp. Read through them to learn about how everything works together. Cut-and-paste these examples freely; that's what they're for.

### Synchronous Get ([.kt][SynchronousGetKotlin], [.java][SynchronousGetJava])

class Item(BaseModel):
    name: str
    description: str | None = None


class ItemV2(BaseModelV2):
    title: str
    summary: str | None = None


app = FastAPI()


@app.post("/items/", response_model=ItemV2)
def create_item(item: Item):
    return {"title": item.name, "summary": item.description}
```
