Elysium Health

Elysium Health is a New York-based consumer longevity and healthspan company founded in 2014 by MIT biologist Leonard Guarente, Eric Marcotulli, and Dan Alminana, and backed by General Catalyst since 2016. It translates academic aging research into direct-to-consumer supplements and diagnostics — Basis (NAD+ / nicotinamide riboside plus pterostilbene), Matter, Signal, Format, Mosaic, Cofactor, Vision, Senolytic Complex, Creatine+, and the Index biological-age epigenetic test — supported by a scientific advisory board that includes multiple Nobel laureates and by academic partnerships and clinical trials published through its Aging Research Center. Elysium publishes no traditional developer API program; its machine-readable surface is an agent-facing commerce stack on Shopify — a Universal Commerce Protocol (UCP) merchant profile at /.well-known/ucp, a UCP MCP endpoint, a published llms.txt / agents.md agent policy, Shopify Customer Account OIDC discovery, and the storefront product/collection JSON endpoints.

Elysium Health is listed with 3 APIs on the APIs.io network. Tagged areas include Company, Health, Longevity, Supplements, and Consumer Health.

Elysium Health’s developer surface includes documentation, getting-started guide, support, engineering blog, signup flow, pricing, authentication, and 19 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):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

7 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 0.0 — up to +25.0 composite points
Operational Transparency scores 2.6 — up to +12.7 composite points
Access Clarity scores 44.7 — up to +11.1 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/elysium/apis.yml: open an issue on github.com/api-evangelist/elysium 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
IVD, Diagnostics and Surgical Devices (FDA / EU regulated device makers)	undeclared	-	-	-

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 2

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.
