openapi: 3.1.0 info: title: Cresilon Search API version: wp/v2 summary: Public cross-content search over cresilon.com posts and pages. 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 WordPress core search route, which returns lightweight records spanning both the news stream and the static pages. It is the fastest way for an agent to resolve a Cresilon product or clinical topic to a canonical URL. contact: name: Cresilon url: https://cresilon.com/contact-us/ email: info@cresilon.com license: name: Site content — all rights reserved, see Terms of Use url: https://cresilon.com/terms-of-use/ x-apis-io-provenance: method: derived source: https://cresilon.com/wp-json/ derived_on: '2026-08-04' note: Routes enumerated from the live wp-json discovery document (1,021 routes across 45 namespaces); every operation below was probed anonymously and returned HTTP 200.
