  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.
