AI工具专用代理：让API调用持续畅通，不再被限流或封禁

"""Rotating-proxy client for OpenAI-compatible chat APIs (Advanced.name proxies).

Sends each prompt from a file to a chat API through a different proxy, with
retries, and writes the answers to a CSV. Use it only with an API key and a
service you are authorised for. Standard library only. Run: python3 ai_calls.py
