  summary: Anonymously readable WordPress REST content API behind star-therapeutics.com.
  description: The read-only content surface Star Therapeutics exposes at https://star-therapeutics.com/wp-json. Star Therapeutics is a clinical-stage biotechnology company in South San Francisco developing best-in-class antibody therapies in hematology and immunology under a hub-and-spoke model whose spokes include Vega Therapeutics (VGA039, von Willebrand disease) and Electra Therapeutics (ELA-026, secondary HLH). It runs no developer program and markets no product API. This document is an API Evangelist derivation of the WordPress `wp/v2` and `oembed/1.0` route index the site publishes at /wp-json/, restricted to the operations that were verified to return data anonymously on 2026-08-05. Write operations, `/wp/v2/users`, `/wp/v2/settings`, `/wp/v2/menus`, `/wp/v2/themes`, `/wp/v2/plugins`, `/wp/v2/block-types`, `/wp/v2/font-collections`, `/wp/v2/icons`, the `wp-abilities/v1` namespace, the `jet-engine/v1` MCP namespace and the whole plugin-administration surface all require authentication and are deliberately excluded — see x-api-evangelist-provenance.

  x-api-evangelist-provenance: 'Derived by the API Evangelist enrichment pipeline from the live WordPress REST route index at https://star-therapeutics.com/wp-json/ (491 routes across 31 namespaces) and verified against live anonymous responses on 2026-08-05. Every parameter below appears verbatim in the route index `args` for that endpoint, and every collection count in a description was read from the `X-WP-Total` response header on that date. Star Therapeutics publishes no OpenAPI, no developer documentation and no API reference for this surface; the humanURL in apis.yml points at the upstream WordPress REST handbook that defines the wp/v2 contract. The deployment is served by WP Engine behind Cloudflare, page HTML is Elementor-rendered, and API responses carry `x-robots-tag: noindex`. Nothing here was obtained with credentials.'
