  version: wp/v2
  summary: The public, read-only WordPress REST API behind www.arlp.com.
  description: 'Alliance Resource Partners, L.P. (ARLP, NASDAQ: ARLP) publishes no developer portal and no product
    API. Its corporate site at www.arlp.com runs on WordPress (WP Engine) and serves the standard WordPress REST
    API anonymously at https://www.arlp.com/wp-json/. That surface is a real, machine-readable, unauthenticated
    read API over ARLP corporate content: the 12 published site pages (About Us, Our Businesses / Coal Operations
    / Royalties / Other Growth Investments, Sustainability, Careers, Contact, Privacy Statement, Terms of Use),
    the media library, blog posts and comments, the category and tag taxonomies, cross-content search, and the self-describing
    type/taxonomy/status discovery endpoints. This document is DERIVED from the live route discovery document at
    https://www.arlp.com/wp-json/ (saved verbatim alongside it as alliance-resource-partners-wp-routes-original.json);
    every path, method, parameter and parameter schema here comes from that document, and every collection path
    listed was verified to return HTTP 200 anonymously on 2026-09-01. Write methods (POST/PUT/PATCH/DELETE) and
    the administrative namespaces (settings, block-types, wp-abilities, wp-site-health, wp-block-editor, redirection,
    cky, wpe, wp-table-builder, yoast) are deliberately excluded: they exist on the host but return HTTP 401 rest_forbidden
    anonymously and require WordPress Application Passwords. This is a corporate-content API. It is NOT a coal,
    mine-telemetry, logistics or royalty-reporting API - ARLP publishes none, and any such integration is a bilateral
    commercial agreement. Alliance Resource Partners did not author or publish this description; API Evangelist
    derived it from ARLP''s own live discovery document.'
