Description

FreqBlog provides a music-metadata API that returns detailed audio features (BPM, key, mood, energy, genre, ISRC and more) for tracks. You can look up tracks by artist+title, ISRC, or upload audio for analysis and also resolve up to 50 tracks in a single bulk request.

What can you use it for?

Build a DJ set builder that matches songs by BPM and key, tag playlists with mood and energy, or enrich catalogs for recommendations. You can query by artist+title (no Spotify ID needed), upload audio for analysis, or resolve many tracks in one bulk call. There’s a forever-free tier for experimenting and instant paid upgrades for production. Results include BPM, key, mood, genre and ISRC so you can ship features fast.
