Calviri

Calviri is a Phoenix, Arizona biotechnology company, founded in 2017, that develops multi-cancer diagnostic tests and therapeutic and preventative cancer vaccines for dogs and people. Its science rests on RNA-Error Derived Neoantigens (REDNs) — abnormal proteins thrown off by the error-prone RNA processing of tumor cells — which Calviri builds as peptides on semiconductor chips and then queries against an individual's blood for antibody responses, using those antibodies as sensitive biomarkers of cancer. Its lead product, StageOne Plus, is a canine multi-cancer blood test designed to detect stage 1 disease before signs appear, alongside a pipeline of canine and human therapeutic and preventative vaccines and a preventative-vaccine trial (VACCS) that enrolled 800+ dogs. Calviri is a life-sciences company with no developer program, no product API and no developer portal; the only machine-readable surface on calviri.com is the Wix-platform-generated llms.txt and the anonymous site MCP endpoint it advertises.

Calviri publishes 1 API on the APIs.io network. Tagged areas include Company, Biotechnology, Life Sciences, Health, and Cancer Diagnostics.

Calviri’s developer surface includes YouTube channel, authentication, and 14 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/.

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 github.com/api-evangelist/calviri: open an issue to ask a question, or submit a pull request to add artifacts.

    It is the standard Wix "Site Visitor Assistant" server that the Wix platform provisions for every site — not an API Calviri
    built — but it is live and callable without credentials, and `initialize` plus `tools/list` both returned 200 on 2026-08-09
    exposing nine tools (GetBusinessDetails, SearchInSite, SearchSiteApiDocs, GenerateVisitorToken, CallWixSiteAPI, ExecuteWixAPI,
    BrowseWixRESTDocsMenu, ReadFullDocsArticle, ReadFullDocsMethodSchema). It reads only information that is already public
    on the website.
