openapi: 3.2.0 info: title: IgGenix Content API (WordPress REST wp/v2) Taxonomy API version: wp/v2 summary: 'Public read surface of iggenix.com content: press releases, peer-reviewed publications, conference abstracts, careers postings, pages, media, taxonomies and site search.' description: 'IgGenix publishes iggenix.com on WordPress (hosted on WP Engine as iggenix.wpengine.com), which exposes the WordPress REST API at https://iggenix.com/wp-json/. The wp/v2 namespace is anonymously readable and returns the company''s press releases, peer-reviewed publications, conference abstracts, a careers post type, pages, media library, 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://iggenix.com/wp-json/ on 2026-08-22 — every path, method, parameter, type, enum and default below is taken verbatim from that descriptor, and each collection was confirmed with an anonymous GET. IgGenix 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); GET /wp/v2/settings and the wp-abilities/v1 registry return 401 rest_forbidden anonymously. NOTE ON THE SITE ITSELF: on the date of derivation the HTML front end at iggenix.com served another company''s home page (iECURE, canonical https://iecure.com/) for the site root and for every unmatched path, including /privacy-policy/ and /the-iggenix-team/. The REST API and the custom-post-type archives (/publications/, /abstracts/, /pressreleases/) are unambiguously IgGenix''s — the route index reports name "IgGenix" and returns IGNX001 peanut-allergy content — so this contract is attributed to IgGenix. The HTML routing defect is recorded in review.yml.' contact: name: IgGenix url: https://iggenix.com/ email: info@IgGenix.com x-derived-by: API Evangelist enrichment pipeline x-derived-from: https://iggenix.com/wp-json/ x-derived-on: '2026-08-22' x-provider-published: false servers: - url: https://iggenix.com/wp-json description: Production tags: - name: Taxonomy paths: /wp/v2/categories: get: operationId: getCategories summary: GET /wp/v2/categories tags: - Taxonomy parameters: - name: context in: query required: false schema: type: string enum: - view - embed - edit default: view description: Scope under which the request is made; determines fields present in response. - name: exclude in: query required: false schema: type: array default: [] items: type: integer description: Ensure result set excludes specific IDs. - name: hide_empty in: query required: false schema: type: boolean default: false description: Whether to hide terms not assigned to any posts. - name: include in: query required: false schema: type: array default: [] items: type: integer description: Limit result set to specific IDs. - name: order in: query required: false schema: type: string enum: - asc - desc default: asc description: Order sort attribute ascending or descending. - name: orderby in: query required: false schema: type: string enum: - id - include - name - slug - include_slugs - term_group - description - count default: name description: Sort collection by term attribute. - name: page in: query required: false schema: type: integer default: 1 minimum: 1 description: Current page of the collection. - name: parent in: query required: false schema: type: integer description: Limit result set to terms assigned to a specific parent. - name: per_page in: query required: false schema: type: integer default: 10 minimum: 1 maximum: 100 description: Maximum number of items to be returned in result set. - name: post in: query required: false schema: type: integer description: Limit result set to terms assigned to a specific post. - name: search in: query required: false schema: type: string description: Limit results to those matching a string. - name: slug in: query required: false schema: type: array items: type: string description: Limit result set to terms with one or more specific slugs. responses: '200': description: Success.
