Production readiness

API 클라이언트를 프로덕션 준비 상태로 만들기

Production reliability comes from treating status codes differently, keeping retries bounded, reusing ETags, and choosing scheduled REST, SSE, or webhooks for the job.

import os
import requests
from urllib3.util.retry import Retry

session = requests.Session()
retry = Retry(total=3, backoff_factor=0.5, status_forcelist=(429, 502, 503, 504))
session.mount("https://", requests.adapters.HTTPAdapter(max_retries=retry))

response = session.get(
    "https://api.fxmacrodata.com/v1/announcements/eur/inflation",
    params={"api_key": os.environ["FXMD_API_KEY"], "limit": 5},
    headers={"Accept-Encoding": "gzip"},
    timeout=(3.05, 20),
)
response.raise_for_status()

예상 결과: A bounded client that handles transient failures without retry storms and is ready to add ETag-based conditional refreshes.
