Willie's Reserve

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.

Willie’s Reserve publishes 1 API on the APIs.io network. Tagged areas include Company, Cannabis, Consumer Products, Retail, and E-Commerce.

Willie’s Reserve’s developer surface includes documentation, authentication, support, engineering blog, and 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/willie-s-reserve: open an issue to ask a question, or submit a pull request to add artifacts.
