Categories, tags and the taxonomy registry for iggenix.com, exposed as JSON by the WordPress REST API. Anonymously readable; categories return one term (Uncategorized) and tags are empty, so the content on this site is organized by post type rather than by taxonomy. 16 operations across 6 paths; the write methods require authentication.
Every API here is available over the APIs.io API and to AI agents over MCP.
One button, every client — Claude, Cursor, VS Code and the rest.

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.'
