  title: Ionetix Content API (WordPress REST wp/v2) Taxonomy API
  version: wp/v2
  summary: Categories, tags and taxonomy registrations used to classify ionetix.com content.
  description: 'Ionetix publishes ionetix.com on WordPress, which exposes the WordPress REST API at https://ionetix.com/wp-json/. The wp/v2 namespace is anonymously readable and returns the company''s news and careers posts, cardiac-PET / N-13 Ammonia / alpha-therapy product pages, leadership profiles, media library (including the ION-12SC cyclotron data sheet PDFs), taxonomies and a site-wide search endpoint as JSON.


    This document was DERIVED mechanically by API Evangelist from the route-discovery document served at https://ionetix.com/wp-json/ on 2026-08-23, and from the per-route JSON Schema each collection returns to an HTTP OPTIONS request — every path, method, parameter and schema below is taken verbatim from those descriptors. Ionetix does not publish an OpenAPI definition of its own, and this is not a product API: it is the content API the CMS exposes. Write operations exist on these routes but require authentication (WordPress Application Passwords over HTTP Basic).'
