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 publishes 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.

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/linusbio: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
