How to use Holy-Unblocker dynamically with just a URL?

[beyondyoda]

Hi, I’m self-hosting Holy-Unblocker and want to use it purely as a backend proxy — without the UI.

Can I directly access sites like this?
http://localhost:8080/service/

If yes:
What's the correct way to encode URLs externally (e.g., from a script)?

Thanks in advance!
