  title: LanzaTech WordPress REST block-directory categories API
  version: wp/v2
  description: 'The public WordPress REST API served by lanzatech.com. Derived faithfully from the provider''s own live discovery document at https://lanzatech.com/wp-json/ on 2026-07-19. Alongside the standard WordPress content types (posts, pages, media, categories, tags), LanzaTech publishes five custom content types that model the company itself: news (external news coverage), employee, board-member, download (published reports and life-cycle assessments) and testimonial. Read operations are publicly accessible without authentication; write operations require a WordPress application password.'
