Winc

Winc is a direct-to-consumer online wine club and retailer (winc.com) offering curated, personalized wine subscriptions and single-bottle purchases matched to a member's palate profile. The winc.com storefront runs on Shopify and exposes a modern agentic-commerce surface: a hosted UCP (Universal Commerce Protocol) MCP endpoint, Shopify Customer Account API authentication (OpenID Connect), and published /llms.txt and /agents.md agent instructions that let AI shopping assistants discover the catalog, build carts, and drive buyer-approved checkout. Originally surfaced as a VC portfolio company and enriched from its public agent-facing surface by the API Evangelist enrichment pipeline.

Winc publishes 1 API on the APIs.io network. Tagged areas include Company, Wine, E-Commerce, Retail, and Subscription.

Winc’s developer surface includes authentication and 10 more developer resources.

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.

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/winc: open an issue to ask a question, or submit a pull request to add artifacts.
