ClawRouter is an LLM router built for autonomous agents that performs smart model selection and routing entirely locally.
The tool solves the fundamental problem that autonomous agents cannot create accounts, enter credit cards, or manage API keys—they can only sign transactions. ClawRouter enables agents to operate independently by using wallet signatures for authentication instead of API keys and USDC micropayments via the x402 protocol instead of credit cards. It analyzes each request across multiple dimensions and routes to the cheapest capable model in under one millisecond, running entirely locally with zero external dependencies. The routing logic is open source and available separately, allowing developers to understand and customize how model selection works.
Developers should choose ClawRouter if they are building autonomous agents that need to call language models without human intervention or account management. It suits projects where cost optimization matters—the tool can reduce API costs significantly by automatically selecting the most economical model that meets the request's requirements. The project includes free open-weight models with no signup required, making it possible to start development at zero cost. Compared to alternatives like OpenRouter, LiteLLM, Martian, and Portkey, ClawRouter uniquely combines smart open-source routing, local execution, wallet-based authentication, per-request USDC payments, and agent-ready design without requiring accounts or credit cards.
The project maintains active development with regular updates to its routing logic and model support. The codebase is written in TypeScript and published as an npm package, indicating ongoing maintenance and accessibility for JavaScript-based agent frameworks. The tool is distributed under an MIT license, allowing broad adoption and modification by developers building agent infrastructure.
