Kate Farms

Kate Farms is a Santa Barbara, California nutrition company that makes USDA-certified-organic, plant-based (organic yellow pea protein) medical nutrition formulas and shakes for tube feeding and oral supplemental nutrition, used in more than 1,400 hospitals and prescribed across pediatric and adult care. The company sells direct to consumers through a Shopify storefront at shop.katefarms.com and publishes clinical and reimbursement material for healthcare professionals at katefarmsmedical.com. Its public machine-readable surface is commerce-side rather than a developer product: the storefront exposes an anonymous-introspectable Shopify Storefront GraphQL API, an agent-facing llms.txt / agents.md, and a live Universal Commerce Protocol (UCP) merchant profile with an MCP endpoint for agent-driven catalog search, cart and checkout.

Kate Farms publishes 2 APIs on the APIs.io network. Tagged areas include Company, Nutrition, Medical Nutrition, Health, and Food and Beverage.

Kate Farms’ developer surface includes documentation, getting-started guide, authentication, support, signup flow, and 22 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/.
