LinusBio

LinusBio (Linus Biotechnology Inc.) is a New York-based precision-medicine company spun out of the Mount Sinai Institute for Exposomic Research that commercializes "temporal exposomics sequencing" — a robotics, laser-ablation and mass-spectrometry platform that reads a single strand of hair like growth rings to reconstruct hundreds of time-resolved measurements of a person's chemical and biological exposures, then runs them through an AI pipeline to produce biomarkers. Its clinical product ClearStrand-ASD (formerly StrandDx-ASD) is an FDA Breakthrough Device-designated laboratory developed test run in a CLIA-certified lab to help rule out autism spectrum disorder in children from one month to ten years of age, and its consumer product Traced is a $299 at-home environmental exposure test measuring 15 elements across a 30-day timeline. LinusBio publishes no developer program, no OpenAPI and no public REST API; its only machine-callable surface is the Shopify-hosted Universal Commerce Protocol (UCP) MCP endpoint on the traced.life storefront, through which an agent can search the catalog, build a cart and open a checkout for the Traced test under a buyer-approval rule.

LinusBio is listed with 1 API on the APIs.io network. Tagged areas include Company, Health, Diagnostics, Precision Medicine, and Biotechnology.

LinusBio’s developer surface includes engineering blog, support, pricing, documentation, getting-started guide, authentication, and 16 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
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
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

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/linusbio/apis.yml: open an issue on github.com/api-evangelist/linusbio 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	-	-	-
GA4GH Genomics Standards (htsget, DRS, TES, WES, Beacon, Passports)	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.
