An LLM router that signs transactions, not NDAs

What it does ClawRouter is a local TypeScript proxy that sits between your AI client and 55+ LLM providers. It scores each request across 15 dimensions, picks the cheapest capable model, and routes it in under 1ms. Payment happens per-request via USDC on Base or Solana using the x402 protocol — no accounts, no API keys, just wallet signatures. Ten NVIDIA models are free without any crypto setup.

The interesting bit The “agent-native” framing is the real angle. Every other router assumes a human with a credit card and a dashboard login. ClawRouter assumes the opposite: the caller is code that can sign a blockchain transaction but can’t click “I agree to terms.” The x402 micropayment protocol turns HTTP 402 Payment Required into a machine-payable endpoint.

Key highlights

• 100% local routing, zero external API calls for the routing decision itself
• Wallet signature replaces API key authentication
• Four routing profiles: free, auto (default), eco, premium
• Standalone proxy mode for any OpenAI-compatible client (continue.dev, Cursor, etc.)
• OpenClaw plugin with one-shot install script
• Also supports image generation via /cr-imagegen with multiple providers

Caveats

• The “10 free models” and “8 free models” claims differ between sections of the README; the exact free count is unclear
• Bare npm install -g leaves OpenClaw integration broken unless you run clawrouter setup afterward
• The comparison table claims “55+ models” but the routing examples show model names that don’t map cleanly to real-world versions (e.g., claude-opus-4.8, gpt-5.3-codex) — verify actual model availability against live endpoints

Verdict Worth a look if you’re building autonomous agents that need to pay their own way, or if you want smart routing without cloud dependencies. Skip it if you’re a human who already has API keys and a working credit card — OpenRouter or LiteLLM may be simpler.
