REST API Access
Build integrations and automations against the bpmdex REST API. Secured by Azure Entra ID — your tokens, your data, your rules. Full OpenAPI documentation available.

How It Works

From collection to crate in four steps

1
Connect your library
Import tracks via the web interface or directly through the REST API. Drag-and-drop uploads support MP3, WAV, FLAC, AIFF, and other common DJ formats.
2
Analyze & enrich
bpmdex automatically detects BPM and musical key for each track. Supplement with manual tags — genre, energy, mood, custom labels — to build a metadata-rich catalog.
3
Search & discover
Use the smart search to query across any combination of attributes. Save searches as dynamic crates that update automatically as new music is added.
4
Play & integrate
Access your library from any browser or the mobile app. Use the API to push data to Rekordbox, Serato, or any custom workflow. Your library travels with you.
