  title: Hydrostor Discovery API

  description: Public, unauthenticated discovery metadata for hydrostor.ca — the self-describing route index (340 routes across 18 namespaces at capture), the registered content types and taxonomies, the publication statuses, and the public author records. This is the surface that makes the rest of the API machine-readable in the complete absence of any published documentation, and it is what every other artifact in this profile was derived from on 2026-08-22.

  x-api-evangelist-note: Third-party profile by API Evangelist. Hydrostor publishes no developer program; this document describes the anonymously readable WordPress REST content API served from hydrostor.ca, which the site exposes as a self-describing route index. Every path, parameter and schema here was read from the server's own route index and HTTP OPTIONS documents on 2026-08-22 — nothing is invented.
