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.

Regulatory Posture applies to this provider. Its tags matched the Health 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/chill: open an issue to ask a question, or submit a pull request to add artifacts.
