  description: Public, unauthenticated read access to the static marketing, services, investor and policy pages of www.gbrx.com, plus the cross-content search endpoint and the oEmbed discovery endpoint. Verified live on 2026-09-12 at 51 published pages and 191 searchable objects spanning posts, pages and railcars. The search endpoint returns lightweight id / title / url / type / subtype records and is the cheapest way for a machine to enumerate what Greenbrier publishes.

  x-api-evangelist-note: 'Third-party profile. The Greenbrier Companies publishes no developer program; this documents the anonymously readable WordPress REST surface behind www.gbrx.com. Every path, parameter, type, default and enum below was read from the server''s own published route descriptor on 2026-09-12 — nothing is invented. Only the GET methods are documented: write methods exist on the same routes but require WordPress application-password credentials and are not part of the public surface.'
