description: >-
  Audius is a decentralized, open-source protocol. The public REST API is free and unauthenticated for
  read endpoints (tracks, users, playlists, search, resolve). There is no API key, no plan tier, and
  no per-call charge. Self-hosting a discovery node is possible.
notes: Free, open-source, no API key required for public read endpoints.
