  title: Alzheon Content API (WordPress REST) Users API
  version: wp/v2
  summary: Read-only access to the press releases, news, pages and media published on alzheon.com.
  description: 'Alzheon does not operate a product or developer API. Its corporate site, alzheon.com, does however serve the standard WordPress REST API anonymously at `https://alzheon.com/wp-json`, which makes the company''s press releases, in-the-news items, science/pipeline pages, media library and taxonomies machine-readable without a key.


    This document was DERIVED by API Evangelist from the provider''s own live route index (`GET https://alzheon.com/wp-json/`) on 2026-07-31. Every path, method, parameter name, type, default, enumeration and parameter description is copied verbatim from that index; nothing was invented. Only routes that were individually probed and observed to return HTTP 200 to an anonymous request are included — administrative routes such as `/wp/v2/settings` and `/wp/v2/plugins` return 401 and are deliberately omitted, as are all write operations, which require WordPress application-password credentials the company does not issue publicly.


    This is NOT a first-party API product and Alzheon publishes no developer documentation, SDKs, support channel or terms of use for it. Treat it as an incidental content surface.'
