  version: wp/v2
  description: The public, anonymously-readable content API exposed by engrail.com. Engrail Therapeutics is a clinical-stage
    precision-neuroscience company and does not publish a product API; this contract is the read-only content surface
    its WordPress-backed corporate site exposes at /wp-json/wp/v2. It is DERIVED mechanically from the provider's
    own route-discovery document - every path, method, and parameter below is copied verbatim from https://www.engrail.com/wp-json/
    . Write operations exist on the live host but require authentication and are deliberately not modelled here.
