# Willie's Reserve

**Website:** https://williesreserve.com/  
**APIs profiled:** 1

Willie's Reserve is the cannabis brand founded around Willie Nelson's name and legacy, selling premium cannabis products direct to consumers from williesreserve.com. It is a consumer products company rather than a software vendor, and it publishes no developer program, no OpenAPI and no SDKs. It does, however, operate a real and unusually complete agent commerce surface: a live, anonymously reachable Model Context Protocol endpoint at /api/ucp/mcp implementing the Universal Commerce Protocol shopping service, a machine-readable UCP merchant profile at /.well-known/ucp, an /agents.md instruction document mirrored at /llms.txt, a dedicated agentic-discovery sitemap, and robots.txt policy language requiring human approval before any agent completes a payment.
