  version: wp/v2
  summary: Public read surface of the media library behind cresilon.com.
  description: Cresilon publishes its corporate website (cresilon.com) on WordPress (WordPress.com Atomic hosting, nginx) with the core WordPress REST API enabled and anonymously readable. This specification was DERIVED by discovering the live route index at https://cresilon.com/wp-json/ and probing each route for anonymous access; only routes verified to return HTTP 200 without credentials are documented here as public operations. Write operations exist on the same routes but require authentication (WordPress cookie + X-WP-Nonce, or Application Passwords) and are not documented here; anonymous requests to them return HTTP 401. This is NOT a product API offered by Cresilon to customers — Cresilon is a biotechnology and medical-device manufacturer, not a software vendor. This is the content API of their marketing site, captured for discovery purposes. This document covers the `attachment` type — product photography, TRAUMAGEL and VETIGEL imagery, Instructions For Use and clinical publication documents, video posters and press assets, each with the generated size variants WordPress produces. At time of capture the collection held 1,307 attachments.
