  summary: Anonymously readable WordPress REST content API behind www.flaretx.com.
  description: The read-only content surface Flare Therapeutics exposes at https://www.flaretx.com/wp-json. Flare Therapeutics is a clinical-stage biotechnology company at 400 Technology Square, Cambridge, Massachusetts, developing small-molecule precision medicines against transcription factors — historically "undruggable" targets — using a switch-site discovery platform. Its lead programs are FX-909 in advanced urothelial cancer and FX-111 in prostate cancer, and it runs a discovery collaboration with Roche. It operates 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 verified to return data anonymously on 2026-08-12. 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 `aiarc/v1`, `wpe_sign_on_plugin/v1`, `google-site-kit/v1`, `yoast/v1`, `wpgmza/v1`, `akismet/v1`, `post-duplicator/v1`, `mtphrSettings/v1` and `gosmtp-smtp` plugin namespaces and the whole plugin-administration surface all require authentication or are administrative 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://www.flaretx.com/wp-json/ (259 routes across 16 namespaces) and verified against live anonymous responses on 2026-08-12. 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. Flare 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 (nginx, x-powered-by WP Engine) and API responses carry `x-robots-tag: noindex`. Nothing here was obtained with credentials.'
