Summary
Wraps an anonymous REST API that lets Claude search eSIM plans across 193 countries, create orders with Stripe or Bitcoin payment rails, and check order status. No API key required. The same API powers a Custom GPT in the ChatGPT store and a Claude Skill. Orders are idempotent with 24-hour replay windows, rate limited to 10 creations per hour per IP. Payment confirms and the QR code lands in the buyer's email within 30 seconds. Useful when you're building travel agents or itinerary tools and want connectivity handled in-context without sending users to a separate purchase flow. Source includes the MCP server, GPT config, and Claude Skill in a public monorepo.
