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 is listed with 2 APIs on the APIs.io network. Tagged areas include Company, Nutrition, Medical Nutrition, Health, and Food and Beverage.

Kate Farms’ developer surface includes engineering blog, 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.

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/.

Agent readiness — checks not met, largest first (exact, from this profile):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

3 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 9.3 — up to +22.7 composite points
Access Clarity scores 34.2 — up to +13.2 composite points
Operational Transparency scores 0.0 — up to +13.0 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/kate-farms/apis.yml: open an issue on github.com/api-evangelist/kate-farms to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Open Food Facts brand owners (food product data)	standard	17.2 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 3

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
