description: '4D Path, Inc. is a Newton, Massachusetts computational-pathology company founded
  in 2016 that builds the Q-plasia OncoReader (QPOR) platform, a patented, cloud-based precision
  oncology and computer-aided cancer diagnostic system. Rather than conventional image-classification
  AI, QPOR applies statistical physics and cancer biology to digitized H&E-stained whole-slide
  biopsy and resection images to measure and quantify cell-cycle deregulation and tumor immune
  microenvironment dynamics, producing biomarker profiling, grading and therapy-response
  prediction without additional molecular assays such as IHC, FISH, RNA-Seq or NGS. Its lead
  software-as-a-medical-device product, 4D Q-plasia OncoReader Breast, received FDA Breakthrough
  Device Designation in November 2020, and the company has partnered with PathPresenter to
  distribute the reader inside the ClinPx clinical workflow platform. 4D Path publishes no public
  developer program, API reference, SDK or machine-readable contract of any kind — see x-coverage.'

  detail: >-
    4D Path ships the QPOR reader as a software-as-a-medical-device product consumed by
    pathologists inside PathPresenter's ClinPx whole-slide viewer, and 4dpath.com is a
    WordPress marketing site with no developer, API, documentation or integration section
    anywhere in its nav or sitemap; the one API-shaped host that resolves in DNS,
    api.4dpath.com, is an Azure Web App that answers Microsoft's stock 404 page for its own
    root and for every contract path probed, including /openapi.json and
    /swagger/v1/swagger.json.
