Elk Client API
Elk's own server surface, served by its Nuxt runtime at https://elk.zone/api. Four endpoints: list the Mastodon-compatible instances offered in the sign-in picker, build the instance authorize URL, complete the OAuth authorization-code callback, and (operator-only) clear a cached OAuth app registration. It is not a marketed, versioned or documented public API, and it is not the Mastodon API — timelines, posts and notifications are served by the user's own instance, not by Elk.
