  version: wp/v2
  summary: Anonymous read access to ARC investment priorities, local development districts, investments in action,
    events and staff.
  description: 'The programmatic side of the Appalachian Regional Commission''s WordPress content model, exposed
    as custom post types on the `wp/v2` namespace: the nine ARC investment priorities, the 74 Local Development
    Districts (also called Area Development Districts, Councils of Governments or Regional Planning and Development
    Commissions) that deliver ARC investment across the 423-county region, 17 Investments in Action success stories,
    163 events, and 120 staff and state-partner profiles. Record counts observed live 2026-09-07.


    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.'
