Changelog

All notable changes to the MIPPIA API will be documented in this file.

v1.1.2 (2026-09-28)

Added

  • Plagiarism total_scores: The plagiarism result now includes a song-level summary, result.total_scores, with the same overall similarity percentage shown on the MIPPIA website (overall_score), the matched reference track, and a per-category breakdown (by_category) with instrument, chord, and rhythm scores per reference track.

  • Existing segment-level fields (signature, vocal, inst, topline) are unchanged. No client changes are required.

v1.1.1 (2026-02-09)

Changed

  • Pre-upload system: Audio files are now uploaded separately via POST /api/v1/music, which returns a musicId. All analysis endpoints (ai-detection, plagiarism, lyric-transcription) now accept musicId instead of direct file upload.

  • Upload Music API: New endpoint POST /api/v1/music for uploading audio files before analysis.

  • Updated Quick Start: Added upload step to the getting started guide.

Migration from v1.1

  • Replace direct file uploads (-F "file=@audio.mp3") with a two-step process:

    1. Upload file: POST /api/v1/music → receive musicId

    2. Analyze: POST /api/v1/{endpoint} with {"musicId": "..."} in JSON body
