  summary: The anonymously readable WordPress REST content API behind zetagen.com.
  description: Zetagen Therapeutics runs no developer program and publishes no OpenAPI. This document is an API Evangelist derivation of the WordPress REST route index the site publishes at https://zetagen.com/wp-json/ (349 routes across 17 namespaces), narrowed to the operations that were verified to return data anonymously on 2026-08-05. Every write route and the entire plugin-administration surface is excluded — those require an authenticated WordPress user and were never exercised. The contract semantics (pagination, field selection, error envelope) are upstream WordPress REST behaviour, documented at https://developer.wordpress.org/rest-api/.
