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, Ecommerce, Retail, and Subscription.

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