  summary: The public, anonymous WordPress REST API behind www.order.co.
  description: 'Order.co runs www.order.co on WordPress and leaves the WordPress REST API open for anonymous reads. It is not the Order.co procurement API — that surface is customer- and vendor-gated and has no public documentation — but it is a real, first-party, self-describing machine-readable API, and it carries content an agent actually wants: 271 blog posts, 47 pages, 36 customer stories, 6 vendor stories, 21 ebooks, 10 webinars, 18 tools, 2 spend insights, 873 FAQ entries and 142 testimonials, indexed by the first-party `industry` and `use_case` taxonomies.


    This document is GENERATED by API Evangelist from the site''s own discovery document at https://www.order.co/wp-json/ (saved verbatim as examples/orderco-content-discovery.json) and from live anonymous probes on 2026-08-04. Every path, parameter, enum and default here is read out of that discovery document; nothing is invented. Only routes that were verified to return HTTP 200 anonymously are included — write routes and the administrative namespaces (redirection/v1, post-smtp, psd/v1, leadin/v1, wp-abilities/v1, wp-site-health/v1, wp/v2/users, wp/v2/settings) are deliberately excluded because they return 401 rest_forbidden to the public.'
