  title: ReccoBeats Album Track API
  description: ReccoBeats is a free music recommendation and database API. It serves track, artist, and album metadata from a database of millions of tracks, generates track recommendations from seed tracks/artists/albums, and returns Spotify-style audio features (acousticness, danceability, energy, instrumentalness, liveness, loudness, speechiness, tempo, valence) either for a catalog track by ID or extracted directly from an uploaded audio file. Resources are addressed by a ReccoBeats UUID (v4) or by a Spotify Base-62 ID. No API key or authentication is required. The API enforces internal rate limits and returns HTTP 429 with a Retry-After header when throttled.
