 ## 🙏 Acknowledgments
 
-Special thanks to **CLIProxyAPI** - the original Go implementation that inspired this JavaScript port.

+- **CLIProxyAPI** — original Go implementation that inspired this JavaScript port.
+- **[RTK](https://github.com/rtk-ai/rtk)** ![Stars](https://img.shields.io/github/stars/rtk-ai/rtk?style=flat&color=yellow) — Rust token-saver. 9Router ports its compression pipeline to JS → **−20-40% input tokens** on every request.

+Huge thanks to these authors — without their work, 9Router's token-saving features wouldn't exist. ⭐ them on GitHub!
