Use dataclasses for response

[baffelli]

Instead of directly accessing json, you could define a few helper dataclasses or pydantic models:

You're suggesting something like the following?

from pydantic import BaseModel

class KeyResponse(BaseModel):
    public: str
    private: str

response_model = KeyResponse.model_validate(response.content.decode())
pub_key = response_model.public
priv_key = response_model.private

[baffelli]

Yes, correct. I think it's a bit safer and slightly more ergonomic
