  summary: oEmbed 1.0 provider endpoint behind leafforlife.com.
  description: The read-only content surface LEAF4Life exposes at https://leafforlife.com/wp-json. LEAF4Life Inc. is a privately held clinical-stage biopharmaceutical company in Woburn, Massachusetts developing KizaVie™ (LEAF-4L6715), a proprietary liposomal formulation of transcrocetin for hypoxia-related disorders. It runs no developer program and markets no product API. This document is an API Evangelist derivation of the WordPress REST route index the site publishes at /wp-json/, restricted to operations verified to return data anonymously on 2026-08-25. This document covers the oEmbed 1.0 provider route. /oembed/1.0/proxy is a consumer-side helper that requires credentials and is excluded.

  x-api-evangelist-provenance: Derived by the API Evangelist enrichment pipeline from the live WordPress REST route index published at https://leafforlife.com/wp-json/ (150 routes across 7 namespaces) and verified against live anonymous responses on 2026-08-25. Every parameter below appears verbatim in that route index's `args` 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. LEAF4Life publishes no OpenAPI, no developer portal 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. Routes that returned HTTP 401 anonymously (/wp/v2/settings, /wp/v2/block-types, /wp/v2/menu-items, /wp/v2/template-parts, the whole akismet/v1, wp-super-cache/v1, wp-site-health/v1 and wp-abilities/v1 namespaces) and every write method are deliberately excluded. Nothing here was obtained with credentials.
