Tonwed/upi-qr-extractor-standalone — reverse-engineered prompt

Build me a very simple standalone web page for extracting UPI payment info from a ChatGPT session.

I want one clean page where I can paste either a session token, cookie, or full session JSON, submit it, and get back the ChatGPT payment link plus the UPI URI if one is available. Please keep it minimal and focused, no login, no admin panel, no database, no extra bot features, just the extractor itself.

It should send the request through a server side proxy when proxy settings are provided, and also work with direct connection if no proxy is configured. Make proxy setup easy through environment variables, including support for multiple proxies and retry attempts. The app should only use the credentials for the current request and never save them permanently.

Please make it ready to run locally and suitable for server deployment over HTTPS. A clean UI with clear input boxes, submit button, loading state, success and error messages is enough. If you need details, check current docs online.
