Incorrect return type

I am getting an error when trying to use the following method
```py
metalv1.UsagesApi(equinix_client).find_project_usage("")
```

```

I am using version 0.10.0
```
equinix==0.10.0
```

It would seem that a string is expected but a float is being returned, causing the validation to fail.

Inizia da services/metalv1/models/project_usage.py e usages_api.py, usando come punto di ingresso la risposta di find_project_usage mostrata nel traceback. Confronta i tipi dichiarati del modello con la risposta dell'API per price, quantity e total, quindi verifica che l'endpoint deserializzi quei valori numerici senza errori di validazione di Pydantic.

Scritto dal modello di indicizzazione a partire dal testo della issue.
