Elk

name: Elk
description: 'Elk is a nimble, MIT-licensed Mastodon web client maintained by Anthony Fu, Daniel Roe, Kevin Deng and Patak.
  It runs as a Nuxt 4 progressive web app at elk.zone and connects to any Mastodon-compatible instance the user chooses, speaking
  the Mastodon Client API through Masto.js with WebSocket streaming and Web Push notifications. Elk sells no API product and
  issues no credential of its own: its small server surface at elk.zone/api exists to list sign-in instances and broker the
  OAuth 2.0 handshake with the user''s own server, and every timeline, post and notification call goes to that instance directly.'

  description: '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.'
