  version: wp/v2
  summary: Anonymously readable WordPress REST content API behind grintherapeutics.com.
  description: The read-only content surface GRIN Therapeutics exposes at https://grintherapeutics.com/wp-json. GRIN Therapeutics is a clinical-stage biotechnology company developing radiprodil for GRIN-related neurodevelopmental disorder, tuberous sclerosis complex and focal cortical dysplasia type II; it runs no developer program and markets no product API. This document is an API Evangelist derivation of the WordPress `wp/v2` route index the site publishes at /wp-json/, restricted to the operations that were verified to return data anonymously on 2026-08-04. Write operations, `/wp/v2/settings`, the `wp-abilities/v1` namespace, the `contact-form-7/v1` namespace and the `mailin/v1` namespace all require authentication and are deliberately excluded — see x-api-evangelist-provenance.

  x-api-evangelist-provenance: Derived by the API Evangelist enrichment pipeline from the live WordPress REST route index at https://grintherapeutics.com/wp-json/ (138 routes, namespaces oembed/1.0, contact-form-7/v1, mailin/v1, wp/v2, wp-site-health/v1, wp-block-editor/v1, wp-abilities/v1) and verified against live anonymous responses on 2026-08-04. Generator reported WordPress 7.0.2. Every parameter below appears verbatim in the route index `args` for that endpoint. GRIN Therapeutics publishes no OpenAPI, no developer documentation and no API reference for this surface; the humanURL in apis.yml points at the upstream WordPress REST handbook that defines the wp/v2 contract. Nothing here was obtained with credentials.
