  summary: Anonymous discovery metadata for eridu.ai
  description: 'Anonymous discovery metadata for eridu.ai — the self-describing route index, the registered
    content types and taxonomies, publication statuses, and the public author records. This is the surface
    that makes the rest of the API machine-readable in the absence of any published developer documentation.


    Eridu publishes no developer program, no developer portal and no product API. This document is an
    API Evangelist derivation of the only machine-readable interface the company serves — the WordPress
    core REST API behind eridu.ai — captured from the provider''s own live self-describing route index
    on 2026-08-12. It is read-only and anonymously readable; write methods exist on the same routes but
    require a WordPress user with an application password.'
