"""Utilities for handling API response values and base HTTP API client.
This module provides two categories of utilities:
1. **Response helpers** — :func:`is_truthy` and :func:`is_falsy` handle
APIs that return boolean values as strings (``"true"``, ``"false"``)
rather than native JSON booleans.
2. **Base API client** — :class:`APIClient` provides a reusable base
class for HTTP API clients with consistent timeout handling, header
propagation, and automatic raising on 4xx/5xx responses.
Usage::
from devx.utils.api import APIClient, is_truthy
class MyClient(APIClient):
def __init__(self):
super().__init__(
base_url="https://api.example.com",
headers={"Authorization": "Bearer token"},
)
if not is_truthy(config.get("EnableOpenServer")):
raise ValueError("EnableOpenServer not enabled")
"""

import requests
class APIClient:
"""Base class for HTTP API clients.
Subclasses set ``base_url``, ``headers``, and optionally ``auth`` in
their constructor, then use :meth:`_request` or the convenience
methods (:meth:`get`, :meth:`post`, etc.) to make requests.
All requests raise :class:`requests.HTTPError` on 4xx/5xx responses
via :meth:`requests.Response.raise_for_status`.
