  title: ARC Content API (WordPress REST wp/v2)
  version: wp/v2
  summary: Anonymous read access to ARC newsroom posts, site pages, the media library and site-wide search.
  description: 'The Appalachian Regional Commission publishes www.arc.gov on WordPress, which exposes the WordPress
    REST API at https://www.arc.gov/wp-json/. This document covers the general content surface: the ARC newsroom
    (204 posts as of 2026-09-07), site pages (176), the media library (6,293 attachments, largely PDF reports and
    infographics) and the site-wide search endpoint.


    The `wp/v2` namespace at https://www.arc.gov/wp-json/ is readable anonymously — no key, no OAuth, no registration.
    Write methods are advertised on these same routes but reject anonymous callers (WordPress authenticates writes
    with Application Passwords over HTTP Basic), so only the GET surface is documented here.


    This document was DERIVED mechanically by API Evangelist from the route-discovery document served at https://www.arc.gov/wp-json/
    on 2026-09-07 — every path, method and query parameter below is taken verbatim from that descriptor, and each
    collection route was called live to confirm it answers 200 anonymously. The Appalachian Regional Commission
    does not publish an OpenAPI definition of its own; this is the content API its CMS exposes, not a product API.'
