HPSF Site Discovery API is one of 3 APIs that [High Performance Software Foundation](https://apis.io/providers/hpsf/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Discovery, Content, and WordPress.

The WordPress REST route index at https://hpsf.io/wp-json/ - the anchor the site's RFC 9727 /.well-known/api-catalog linkset points at. It returns the site identity, the 15 registered namespaces, 99 route definitions with their methods and argument schemas, and the Application Passwords authorization endpoint. It is the authoritative machine-readable inventory of what this host exposes, and it is also where the absence shows: wp/v2 is listed as a namespace but every wp/v2 route returns rest_no_route 404, and wp-abilities/v1 returns 401.
