# MusicAPI — AI Music Generation API

> MusicAPI (musicapi.ai) is a production-grade REST API for AI music generation. Developers integrate music creation, transformation, and audio processing into their apps with a single API key. Every call returns studio-quality audio with full commercial rights and no watermarks. Backed by multiple leading models (Suno-class "Sonic", Riffusion, Producer, and Google Lyria 3 Pro) behind one unified API.

## What MusicAPI does

- **Generate music from text or lyrics** — custom mode (full control over lyrics, style, genre, vocals) or simple mode (one prompt). Instrumental or vocal, male or female.
- **Transform existing audio** — extend a track, create a cover in a new style, swap vocals or instrumentals, replace a section, concatenate clips.
- **Process audio** — separate stems (4-track basic or 12-track full), convert to WAV, align lyrics to audio (timestamped/karaoke), detect BPM.
- **Manage assets** — upload audio, create reusable vocal personas, poll task status, fetch results.
- **Commercial-ready** — full commercial rights on every track, no watermark, no per-stream fees.
