GitHub - zacdcook/openclaw-billing-proxy: Route OpenClaw API requests through Claude Code subscription billing instead of Extra Usage
An open-source Node.js proxy that sits between OpenClaw and the Anthropic API and makes OpenClaw's traffic look like a Claude Code session, so requests are billed to your Claude Max/Pro subscription instead of Extra Usage. It performs 7-layer bidirectional request/response rewriting (billing header injection, token swap, trigger-phrase sanitization, PascalCase tool-name renaming, system-template stripping, and reverse mapping) to defeat Anthropic's multi-layer detection introduced after April 4 & April 8, 2026.
