Paige

Paige (Paige AI, Inc.) is a New York City computational-pathology company founded in 2017 out of Memorial Sloan Kettering, and the first company to receive FDA authorization for a clinical AI application in digital pathology (Paige Prostate, De Novo 2021) alongside the FDA-cleared FullFocus whole-slide-image viewer. Its product line spans the Paige Platform, the Alba pathology copilot, OmniScreen, the AppLab third-party AI marketplace, and the openly published Virchow / Virchow2 / PRISM foundation-model family. Paige markets "UnifAI" — an SDK plus a set of APIs for vendor-neutral integration into laboratory workflows — but that developer surface is sold to laboratory customers rather than published: the developer docs host docs.paige.ai no longer resolves for the public. What Paige does publish openly is its research stack: the Paige-AI GitHub organization (paige-ml-sdk, philips-isyntax-rs, cdh1-cancer-res, omniscreen-eval-results) and the paige-ai Hugging Face organization carrying the Virchow and PRISM model weights. Paige was acquired by Tempus AI in September 2025.

Paige is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Machine Learning, Healthcare, and Health.

Paige’s developer surface includes engineering blog, product news, support, signup flow, CLI, changelog, 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.

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

  detail: Paige markets "UnifAI" (an SDK plus APIs powering its AppLab marketplace) but ships that surface only to laboratory
    customers — its developer documentation host docs.paige.ai is CNAMEd to ReadMe.io yet returns Cloudflare error 1014 for
    every path, api.paige.ai/developer.paige.ai/unifai.paige.ai do not resolve at all, and the only public entry point is
    a "Request a trial" sales form.
