```Python
response = requests.get("http://example.com/some/url")
```

Die entsprechende *Pfadoperation* der FastAPI-API könnte wie folgt aussehen:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Sehen Sie sich die Ähnlichkeiten in `requests.get(...)` und `@app.get(...)` an.
