vMusic Xray is a music-sharing platform intended to connect musicians and music industry representatives. Musicians post tracks to be analyzed for acoustical properties by Music Xrayâ€™s Song to Opportunity (S2O) technology. Music Xray will then email the user when an industry professional is looking for music that is comparable to S2Oâ€™s analysis. The S2O Partner API exposes Music Xrayâ€™s song uploading and comparison functionality to business partners. Users who register through a partnerâ€™s API account become affiliates who generate commission for the partner. The API is RESTful and returns XML responses. A Ruby SDK is also available.
