This project is a heavily simplified and refocused derivative of
CLIProxyAPI (https://github.com/router-for-me/CLIProxyAPI), which is also
distributed under the MIT License. The original project supports many AI
providers (Gemini, Codex/OpenAI, Qwen, Kimi, iFlow, Antigravity, Vertex,
Claude, ...) and includes a large management UI, TUI, translator layer, and
multi-protocol entry points. CPA-Claude keeps only the Claude passthrough,
adds slot-based concurrency, per-credential SOCKS/HTTP proxies, and
persistent usage tracking, and removes everything else.

The OAuth refresh flow against Anthropic's token endpoint, the uTLS Chrome
fingerprint transport, and several architectural decisions were taken from
or inspired by the original project. Full credit and thanks to its authors.
