# x402 Commerce: Production-Grade AI Agent Commerce Platform

[![Deploy to Railway](https://railway.app/button.svg)](https://railway.app/new?template=https%3A%2F%2Fgithub.com%2FDisseveru%2Fx402-mcp)

**Status**: ✅ **PRODUCTION-READY** (Aug 6, 2026)

Production-grade suite of monetized tools for autonomous AI agent-to-agent commerce built with:
- **x402 Protocol**: Standard HTTP 402 Payment Required negotiation & cryptographic proof settlement.
- **Bazaar Extension**: Machine-readable capabilities discovery & catalog protocol (`/.well-known/bazaar.json`).
- **Model Context Protocol (MCP)**: Exposes monetized tools directly to Grok, Claude, and LLM agent frameworks.
- **xAI Plugin Marketplace Registration**: Native `xai-org/plugin-marketplace` integration manifest.
