  version: wp/v2
  summary: Anonymously readable WordPress REST content API behind centrexion.com.
  description: The read-only content surface Centrexion Therapeutics exposes at https://centrexion.com/wp-json. Centrexion is a late clinical-stage biopharmaceutical company in Boston, Massachusetts developing non-opioid, non-addictive therapies for chronic pain — led by CNTX-4975, a synthetic trans-capsaicin injected intra-articularly that reversibly deactivates TRPV1-expressing pain fibers — alongside an emerging immunology and inflammation portfolio. It runs no developer program and markets no product API. This document is an API Evangelist derivation of the WordPress `wp/v2` and `oembed/1.0` route index the site publishes at /wp-json/, restricted to the operations that were verified to return data anonymously on 2026-08-09. Write operations, `/wp/v2/settings`, `/wp/v2/menus`, `/wp/v2/menu-locations`, `/wp/v2/themes`, `/wp/v2/plugins`, `/wp/v2/block-types`, `/wp/v2/font-collections`, `/wp/v2/icons`, `/wp/v2/sidebars`, `/wp/v2/widget-types`, the pattern-directory routes, the `wp-abilities/v1` namespace and the whole plugin-administration surface 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://centrexion.com/wp-json/ (320 routes across 10 namespaces) and verified against live anonymous responses on 2026-08-09. Every parameter below appears verbatim in the route index `args` for that endpoint, and every collection count in a description was read from the `X-WP-Total` response header on that date. Centrexion 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. The 14 staff biographies the site publishes are a WordPress custom post type that is NOT registered for REST — it does not appear in /wp/v2/types and has no route — so it is reachable only as HTML and is not modelled here. The deployment is served by nginx on WP Engine, responses carry `x-robots-tag: noindex` and are edge-cached (`x-cacheable: SHORT`, `cache-control: max-age=600`). Nothing here was obtained with credentials.'
