HVMN

HVMN (Health Via Modern Nutrition), now operating as Ketone-IQ, is an a16z-backed human-performance nutrition company founded by Geoffrey Woo and Michael Brandt.

The storefront is agent-native: it publishes /llms.txt and /agents.md agent instructions and implements the Universal Commerce Protocol (UCP) with a live MCP endpoint for agent-driven catalog search, cart, and buyer-approved checkout, backed by Shopify Customer Account OAuth 2.0 / OpenID Connect authentication.

HVMN publishes 1 API on the APIs.io network. Tagged areas include Company, Health, Nutrition, Ketones, and Supplements.

HVMN’s developer surface includes authentication, documentation, pricing, and 10 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.

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/. This rating is computed from github.com/api-evangelist/hvmn: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
