I want to use SecretStr for api_key

[ofk]

When using pydantic_settings, I often read the API key as a SecretStr, so I want to pass it without converting it.

from litellm import completion
from pydantic import SecretStr
from pydantic_settings import BaseSettings, SettingsConfigDict

class Settings(BaseSettings):
    model_config = SettingsConfigDict(env_file=".env")
    api_key: SecretStr

settings = Settings()

response = completion(
  model="gpt-3.5-turbo",
  messages=[{ "content": "Hello, how are you?","role": "user"}],
  api_key=settings.api_key
)
