  title: ADARx STOP-HAE Trial Site Clinics API
  version: '1.0'
  summary: The anonymously readable WordPress REST API behind stophae.com, the STOP-HAE Phase 3 patient site.
  description: stophae.com is the patient-recruitment site for STOP-HAE, ADARx Pharmaceuticals' Phase 3 randomized, double-blind, placebo-controlled study of ADX-324 (onvuzosiran) in hereditary angioedema. Its WordPress install identifies itself as "ADARX1 Patient Website" and registers 226 REST routes across oembed/1.0, wpml/v1, wpml/st/v1, wpml/tm/v1, wpml/ate/v1, otgs/installer/v1, wp/v2, wp-site-health/v1, wp-block-editor/v1 and wp-abilities/v1. The distinguishing feature versus the corporate site is a CUSTOM POST TYPE, `clinic` (rest_base `clinic`, label "Clinics"), which carries 50 published trial-site records and is readable without credentials. The records expose site identifiers (e.g. slug `801-01`), permalinks and dates; the Advanced Custom Fields payload that presumably holds the address and contact detail is NOT projected into REST (`acf` is an empty array on every record), so no location data is available through this API. Derived by the API Evangelist enrichment pipeline from https://stophae.com/wp-json/ and verified against live anonymous responses on 2026-08-06. Only operations that returned data without credentials are modelled. The WPML translation-management namespaces expose their namespace index anonymously but every functional route beneath them is administrative.
