Chill

Chill.com is a natural-supplements and wellness marketplace — a Shopify-hosted store selling premium supplements, skincare, functional beverages, and healthy alternatives aimed at helping people relax, unwind, and beat stress. The store is fully agent-native: it publishes an llms.txt agent guide and implements the Universal Commerce Protocol (UCP) over a live MCP endpoint, letting AI shopping agents search the catalog, build carts, and complete buyer-approved checkout. End-user authentication is Shopify Customer Accounts (OAuth 2.0 + OpenID Connect), and read-only catalog browsing requires no auth. Surfaced as a 500 Global portfolio company and enriched from its public agent-commerce surface.

Chill is profiled on the APIs.io network. Tagged areas include Company, Wellness, Supplements, E-commerce, and Marketplace.

Chill’s developer surface includes documentation, authentication, engineering blog, support, and 12 more developer resources.
