Experience high-quality AI music creation with the Kie AI Music API. Enjoy 20-second streaming, high-concurrency performance, timestamped lyrics, and an AI-powered lyric assistant.

AI-powered music creation with or without lyrics using Kie AI Music V3.5, V4, V4.5, and the newly added V5 models. Generates multiple variations per request. Provides a custom mode (requires style and title parameters) and a simple mode (text-prompt only). Supports both instrumental and vocal tracks. Character limits vary by model. Ideal for developers integrating professional music-generation capabilities into applications. The latest V5 version enhances advanced prompting and delivers coherent progressions and high-fidelity audio with clear instrument separation and stable low-end performance.

Generate Music

Kie AI Music API lyrics-generation functionality creates lyrics for music using AI models without generating audio tracks. It provides a simple and affordable solution for AI-powered lyrics creation with fast response times and customizable options. With API integration, users can leverage enhanced Kie AI Music metatags for complex structures and emotional depth, producing various lyric styles including rock, pop, and rap by combining different musical elements—resulting in more nuanced, arc-driven narratives that align seamlessly with V5’s improved vocal-coherence capabilities.

Generate Lyrics

Kie AI Music API extend-music functionality allows users to lengthen existing audio tracks while preserving their original style and melody. Users can upload audio files and extend them seamlessly, maintaining high-quality output with smooth transitions. The feature supports custom prompts to guide the extension process, enabling users to specify how they want the music expanded. The V5 enhancements deliver superior micro-dynamics and emotional continuity, ensuring extensions feel organic—ideal for evolving complex arrangements without unwanted artifacts.

Extend Music

Kie AI Music API functionality allows users to isolate vocals from complete songs or extract instrumental parts from vocal tracks. The API processes uploaded audio files and returns clean, separated stems, enabling developers to integrate vocal-separation capabilities into their applications for remixing, karaoke creation, music production, and audio-analysis purposes. V5 enhances this further by delivering artifact-free, high-fidelity isolations that capture subtle nuances for professional workflows.

Vocal & Instrument Stem Separation

Kie AI Music API create-music-video functionality generates MP4 videos with visualizations for music tracks. This feature combines AI-generated music with visual elements to create complete audiovisual content. The system can handle the entire production pipeline, including music generation, image creation, video-background generation, and final rendering that merges audio and video components. Incorporating V5’s radio-ready audio quality and emotional vocal arcs ensures more immersive sync, with dynamic audiovisuals that respond to micro-dynamics and style influences for richer, more engaging audiovisual experiences.

Create Music Video

Kie AI Music API upload-and-cover functionality allows users to upload audio files and transform them into new musical styles while preserving the original melody. Users can upload any sound—from recordings to demos—and convert them into complete songs. The cover feature refreshes tracks with new styles while keeping core melodies intact. It supports various audio formats like WAV and enables seamless integration into applications for music transformation and creation. V5 delivers hyper-realistic covers with breathing-infused vocals and genre-blending precision.

OUR VALUES

Why Choose Kie.ai for AI Music API Integration

Udio excels in emotional vocals but lacks Kie.ai’s extensive model versions (up to V4.5+) and audio-upload features, making the Kie AI Music API more versatile for developers. Udio’s pricing is higher for API access, while Kie.ai offers points-based savings.

Kie AI Music API vs Udio

ElevenLabs focuses on voice synthesis but falls short in full-song structure compared to the Kie AI Music API’s long-form tracks and lyric timestamps. Kie.ai also adds video integration, which ElevenLabs currently lacks.

Kie AI Music API vs ElevenLabs Music

Stable Audio is great for open-source experimentation but doesn’t match the Kie AI Music API’s commercial-ready, watermark-free output or high-concurrency support.
