Installation & availability

Six Onchain Router client packages version 0.2.0 are public, MIT-licensed stable releases on npm. OpenClaw 0.2.1 and Hermes 0.2.0 are stable MIT releases installable through their hosts’ native GitHub paths. The Python SDK remains source-only; ClawHub and PyPI listings are not claimed. Verify the @onchainrouter scope, exact version, and repository before installation.

Fastest safe start

Requirements: Node.js 20.18 or newer, macOS or Linux, and a human-controlled terminal.

bash

npm install --global @onchainrouter/cli@0.2.0
onchain-router --version
onchain-router setup
onchain-router policy show
onchain-router unlock
onchain-router models

Version 0.2.0 is the current stable client release. Pin the exact version so an upstream tag change cannot silently alter your install. Before installation, verify the @onchainrouter scope and the OnchainRouter/onchain-router source repository.

Setup, wallet import, funding, unlock, and policy widening are human-authority actions. Run them yourself in a direct terminal. Never put a private key, seed phrase, passphrase, payment payload, proxy bearer, or receipt capability in a prompt, command argument, environment variable, log, screenshot, or issue.

The Python SDK remains a source package that delegates paid execution to the matching CLI. It is not on PyPI.

Agent-host integrations

OpenClaw 0.2.1 is a stable MIT release installed from its immutable GitHub release with OpenClaw's native Git installer: openclaw plugins install git:github.com/OnchainRouter/onchain-router-openclaw@v0.2.1 --force. It is not yet listed on ClawHub.
Hermes Agent 0.2.0 is a stable MIT release installed from OnchainRouter/onchain-router-hermes with Hermes' native Git installer: hermes plugins install OnchainRouter/onchain-router-hermes --enable. It is not a PyPI release, and PyPI is not required for this host-native path.
The portable Agent Skill is public in the client repository and requires the matching Buyer CLI.

Verify the exact organization, repository, version, and release commit before installation. Package stability does not prove a funded request in either host; complete the human-owned Buyer Runtime setup and acceptance flow separately.

Browser Workbench

Open Workbench. This build includes the browser UI. A read-only local preview cannot submit paid requests; use only an explicitly enabled deployment for payments.

Update and verify

Pin exact version 0.2.0. Review release notes before updating, rerun onchain-router doctor, and confirm that the local wallet profile, policy, and receipts remain intact. The product manifest records current publication facts; the live models, pricing, and HTTP 402 challenge remain authoritative for service behavior.
