Two files, one container, one simple solution\!”* We’ve adapted this elegant idea for **2025-era browsers** that now enforce the stricter Private Network Access (PNA) checks.

The [**xlwings Lite documentation**](https://lite.xlwings.org/web_requests?utm_source=chatgpt.com "Web API Requests - xlwings Lite documentation") explicitly suggests using a **CORS proxy** if you don’t control the API, and recommends **hosting your own** for privacy reasons—which is exactly what this solution accomplishes.
