  title: Accelsius Resources Content API
  version: wp/v2
  summary: Public read surface of the Accelsius resource library — blog posts, white papers, case studies,
    infographics, podcasts, videos and press releases.
  description: 'The `post` type behind https://accelsius.com/resources/. Accelsius files every resource
    into one of eight categories — blog, white-paper, press-release, news-article, video, podcast, infographic
    and case-study — and tags them across five topic tags (2pd2c-education, neucool-products, accelsius-news,
    scientific-research, featured). At time of capture the collection held 154 published items (observed
    in the X-WP-Total response header).


    Accelsius publishes accelsius.com on WordPress (WP Engine origin, Cloudflare edge, MalCare firewall)
    with the WordPress core REST API enabled and anonymously readable. This is NOT a product API that
    Accelsius offers to customers — Accelsius manufactures two-phase direct-to-chip liquid-cooling hardware
    and ships no developer program, SDK or product API. It is the content API behind the company marketing
    site, captured for discovery purposes. Anonymous access is read-only: the `Allow` response header
    on every collection is `GET`, and write operations require WordPress cookie authentication with an
    X-WP-Nonce header or an Application Password, returning HTTP 401 to anonymous callers.'

    note: Parameters are transcribed verbatim from the `args` the site publishes for each route in its
      live WordPress route-discovery document at https://accelsius.com/wp-json/ (387 routes across 16
      namespaces). Response schemas are derived from the field names and JSON types observed in live anonymous
      GET responses on 2026-08-06. Every collection operation documented here was probed anonymously and
      returned HTTP 200; routes that returned 401 without credentials (settings, menus, menu-items, templates,
      template-parts, themes, plugins, widgets, block-types, users/me) are deliberately omitted. No operation,
      parameter or field was invented, and no live response value is reproduced here as an example.
