  (text=warppay402) fetched 2026-09-19, and the GitHub organization https://github.com/Warppay402 (3 public repos:
  warppay402-sdk, warppay402-server, sdk-test) plus the maintainer account golfgolfgolf200 that holds the
  older mirrors and the OpenClaw plugin. PyPI (warppay402) 404; no Maven, NuGet, Go, RubyGems, Packagist or

    One official client SDK for the hosted API (@warppay402/sdk, TypeScript, wraps every metered tool and adds a
    LangChain tool factory). @warppay402/server is the provider's own x402 monetization middleware for Hono / MCP /
    Cloudflare Workers — first-party, but a server-side library for building your own metered API rather than a
    client for this one. @warppay402/mcp-client is the stdio bridge into the hosted MCP server. The OpenClaw plugin
    (@warppay402/warppay402-mcp-tools) is published on GitHub / ClawHub only, not on npm.

    All three npm packages were released in the last month: sdk 1.1.11 on 2026-09-19 (16 versions since 2026-08-19),
    server 1.2.8 on 2026-09-16 (17 versions since 2026-08-19), mcp-client 1.0.2 on 2026-08-29. The whole surface is
    about one month old; nothing predates the API it wraps.

    OpenClaw agent plugin (openclaw.plugin.json + SKILL.md) that wraps @warppay402/sdk ^1.0.4; the homepage links
    its ClawHub listing (https://clawhub.ai/warppay402) and uses the repo's logo as og:image. Not on npm (the
    npm search for warppay402 returns only sdk, server and mcp-client), so no registry date is available; the
    repo README states Plugin Version 1.1.0. Its SKILL.md is saved verbatim under skills/.
