## Sneak peek

```python title="quickstart_httpx.py"

from httpx import Client

from pydantic import BaseModel, Field

from typing_extensions import Annotated, Protocol

from combadge.support.http.markers import QueryParam, http_method, path

from combadge.support.httpx.backends.sync import HttpxBackend

# 1️⃣ Declare the response models:

class CurrentCondition(BaseModel):

    humidity: int

    temperature: Annotated[float, Field(alias="temp_C")]

class Weather(BaseModel):

    current: Annotated[list[CurrentCondition], Field(alias="current_condition")]

# 2️⃣ Declare the protocol:

class SupportsWttrIn(Protocol):

    @http_method("GET")

    @path("/{in_}")

    def get_weather(

        self,

        *,

        in_: str,

        format_: Annotated[str, QueryParam("format")] = "j1",

    ) -> Weather:

        raise NotImplementedError

# 3️⃣ Bind the service:

with HttpxBackend(Client(base_url="https://wttr.in"))[SupportsWttrIn] as service:

    # 🚀 Call the service:

    response = service.get_weather(in_="amsterdam")

assert response.current[0].humidity == 71

assert response.current[0].temperature == 8.0

```
