# @xenarch/core — shared types and utilities for Xenarch's x402 MCP server

Xenarch is a non-custodial x402 MCP server that lets AI agents pay for HTTP 402–gated APIs with USDC micropayments on Base L2.

This package is the shared TypeScript types + payment-flow utilities consumed by `@xenarch/agent-mcp`. Most agents and developers should install `@xenarch/agent-mcp` instead.
