Hosted-gateway LLM router that saves 67% on inference costs by forwarding each request to the blockrun.ai gateway, which picks the cheapest model capable of handling it across 55+ models from 9 providers (8 free NVIDIA models). All billing flows through one USDC wallet; you do not hold provider API keys.

This is not a local-inference tool. ClawRouter is a thin local proxy. Your prompts are sent over HTTPS to the blockrun.ai gateway for model execution. If your workload requires inference that never leaves your machine, use a local runtime like Ollama — ClawRouter is not the right tool for that use case.

Data Flow

Your app → localhost proxy (ClawRouter) → https://blockrun.ai/api  (or sol.blockrun.ai/api)
                                              ↓
                                        OpenAI / Anthropic / Google / etc.
                                              ↓
                                        Response → back through proxy → your app

Sent to blockrun.ai on every request: the model name, the full prompt/messages body, sampling params (temperature, max_tokens, tools, etc.), and an X-PAYMENT header containing a signed x402 USDC micropayment.

Not sent: your wallet private key (only the detached payment signature is sent), any other local files, environment variables, or OpenClaw config beyond what's needed for this request.

Blockrun's privacy stance: https://blockrun.ai/privacy. Treat prompts the same way you'd treat prompts sent to any hosted LLM API (OpenAI, Anthropic, etc.) — do not send data you would not share with a third-party API provider.

Credentials & Local Key Storage

ClawRouter does not collect or forward third-party provider API keys. You do not supply OpenAI, Anthropic, Google, DeepSeek, xAI, or NVIDIA credentials — the blockrun.ai gateway owns those relationships.

What models.providers.blockrun stores (fully enumerated):

Field	Sensitive	Purpose
walletKey	Yes	EVM private key used to sign USDC micropayments via x402. Auto-generated locally on first run — no user input required. Never transmitted over the network; only detached payment signatures are sent.
solanaKey	Yes	Solana keypair (BIP-44 m/44'/501'/0'/0'). Auto-derived from the same local mnemonic via @scure/bip32 + @scure/bip39.
gateway	No	Gateway URL. Defaults: https://blockrun.ai/api (Base) · https://sol.blockrun.ai/api (Solana).
routing	No	Optional override of the default four-tier router.

How and where keys are stored:

• Keys live in the OpenClaw user config file — typically ~/.config/openclaw/config.json on Linux, ~/Library/Application Support/openclaw/config.json on macOS, %APPDATA%\openclaw\config.json on Windows — under the models.providers.blockrun path.
• Written by OpenClaw's standard config writer with 0600 permissions on POSIX systems (owner read/write only).
• Stored in plaintext, the same way every OpenClaw provider's API key is stored. ClawRouter does not add an extra encryption layer; your filesystem permissions are the security boundary. If you require an encrypted keystore, run OpenClaw on an encrypted volume (FileVault, LUKS, BitLocker) or use a dedicated burner wallet funded only with what you intend to spend.
• Auto-generation uses @scure/bip39 to produce a 24-word mnemonic, then BIP-44 derivation for both chains. Source: src/wallet.ts.

Operational guidance: treat the wallet as a spending account with a small top-up, not a long-term store of value. Fund it with what you expect to spend on LLM calls. If the host machine is compromised, the wallet key is compromised — rotate and refund.

Supply-Chain Integrity

• Every release is tagged on GitHub: https://github.com/BlockRunAI/ClawRouter/releases
• Every release publishes to npm with a matching version: https://www.npmjs.com/package/@blockrun/clawrouter?activeTab=versions
• The skills/release/SKILL.md mandatory checklist enforces: same version in package.json, matching git tag, matching GitHub release, and matching npm publish.
• To verify locally: npm pack @blockrun/clawrouter@<version> and compare the tarball contents to the tagged commit.

Install

openclaw plugins install @blockrun/clawrouter

The structured install block above tells OpenClaw to install the auditable npm package @blockrun/clawrouter. Source for every version is on GitHub; every release is tagged.

Setup

# Enable smart routing (auto-picks cheapest model per request)
openclaw models set blockrun/auto

# Or pin a specific model
openclaw models set openai/gpt-4o

How Routing Works

ClawRouter classifies each request into one of four tiers:

• SIMPLE (40% of traffic) — factual lookups, greetings, translations → Gemini Flash ($0.60/M, 99% savings)
• MEDIUM (30%) — summaries, explanations, data extraction → DeepSeek Chat ($0.42/M, 99% savings)
• COMPLEX (20%) — code generation, multi-step analysis → Claude Opus ($75/M, best quality)
• REASONING (10%) — proofs, formal logic, multi-step math → o3 ($8/M, 89% savings)

Rules handle 80% of requests in <1ms. Only ambiguous queries hit the LLM classifier ($0.00003 per classification).

Available Models

55+ models including: gpt-5.5, gpt-5.4, gpt-4o, o3, claude-opus-4.7, claude-opus-4.6, claude-opus-4.5, claude-sonnet-4.6, gemini-3.1-pro, gemini-2.5-flash, deepseek-chat, grok-3, kimi-k2.6, kimi-k2.5, and 10 free NVIDIA models (gpt-oss-120b [default], gpt-oss-20b, mistral-small-4-119b, deepseek-v4-pro, deepseek-v4-flash, qwen3-next-80b-a3b-thinking, qwen3-coder-480b, glm-4.7, llama-4-maverick, nemotron-3-nano-omni-30b-a3b-reasoning [vision]).

Built-in Agent Tools

In addition to LLM routing, ClawRouter exposes BlockRun's x402-gated data APIs as ready-to-use OpenClaw tools. Every tool is paid from the same USDC wallet — no extra setup, no extra API keys.
