  description: The read-only content surface NiKang Therapeutics exposes at https://www.nikangtx.com/wp-json. NiKang Therapeutics is a clinical-stage biotechnology company in Wilmington, Delaware, founded in 2017, discovering small molecule oncology medicines against difficult-to-drug targets (HIF2α, CDK2, CDK2/4, KRAS G12D) by structure-based drug design. It runs no developer program and markets no product API. This document covers the three anonymously readable term collections on the deployment plus the taxonomy registry itself.

  x-api-evangelist-provenance: 'Derived by the API Evangelist enrichment pipeline from the live WordPress REST route index at https://www.nikangtx.com/wp-json/ (210 routes across 17 namespaces) and verified against live anonymous responses on 2026-08-26. Every query parameter below appears verbatim in that route index''s `args` block for the endpoint it is attached to, and every collection count quoted in a description was read from the `X-WP-Total` response header on that date. NiKang Therapeutics publishes no OpenAPI, no developer portal, no API reference and no developer program; the humanURL in apis.yml points at the upstream WordPress REST handbook that defines the wp/v2 contract. The deployment is WP Engine behind Cloudflare, the theme is The7, and every /wp-json response carries `x-robots-tag: noindex`. Routes that returned 401 anonymously (/wp/v2/users, /wp/v2/settings, /wp/v2/block-types, wp-abilities/v1, wp-site-health/v1) and every write method are deliberately excluded. Nothing here was obtained with credentials.'
