Complete guide to using Suno API
Kie AI Music API for Cost-Effective AI Music Integration
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.
Main Features of Kie AI Music API
Generate Music
AI-powered music creation with or without lyrics using Kie AI Music V6, V6 Mini, and V6 Wild models. Generates multiple variations per request. Provides a custom mode (requires a title plus at least one of style, lyrics, or negative tags) and a simple mode (lyrics are generated automatically from your idea; requires at least one of style, lyrics, or an image, video, or audio reference). Supports both instrumental and vocal tracks. Ideal for developers integrating professional music-generation capabilities into applications.
Generate Lyrics
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.
Extend Music
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.
Vocal & Instrument Stem Separation
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.
Create Music Video
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.
Upload And Cover Audio
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.

Kie AI Music API vs Competitors
Kie AI Music API vs Udio
Udio excels in emotional vocals but lacks Kie.ai’s extensive model versions (up to V6) 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 ElevenLabs Music
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 Stable Audio 2.0
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.
