Ultra-low cost
Pay per track, not per GPU hour
Volume-based pricing that scales with you. No minimum commitments, no idle GPU charges. Pay only for the tracks you generate, up to 20× lower than centralized music APIs.
-
Fast generation
From MVP to millions, zero config
Async pipeline returns a download URL via webhook or status-poll endpoint. Auto-scaling infrastructure handles bursts from 1 to 100,000 concurrent requests. Built-in rate limiting, retry logic, and request queuing included.
-
Unified API
One key, every modality
One endpoint, multiple open-source music models like ACE-Step. Generate music alongside image, video, speech, and transcription with a single API key, single billing account, single response contract.
Generate the right sound for every use case
One API, endless creative possibilities
What it does
Generate unique background music or vocal tracks for every video, episode, or reel. Describe the mood — "upbeat lo-fi hip hop, 90 BPM" — and get a unique track ready to use. Add lyrics or keep it instrumental.
How it works
Send a text prompt with genre, mood, and BPM to the API. Receive a download URL via webhook or poll the status endpoint. Integrate into your CMS, video editor plugin, or content pipeline for automated music at scale.
Key Benefits
-
Unique Tracks No Licensing
Every generated track is unique — no copyright claims on your content
-
YouTube & TikTok Video Ready
Background music that matches your content — no copyright claims
-
Podcast Audio Intros & Beds
Custom jingles, transitions, and ambient beds tailored to your show
What it does
Generate adaptive soundtracks, ambient layers, and background music on the fly. Describe "dark orchestral tension, 60 BPM" for a boss fight or "peaceful forest ambience" for exploration. Score entire games without a composer invoice.
How it works
Call the API from your game engine or build pipeline. Generate tracks for different scenes, moods, and intensity levels. Use the BPM and duration controls to match exact gameplay timing. Batch-generate entire soundtracks during development.
Key Benefits
-
Soundtracks Full Score
Complete game soundtracks generated programmatically
-
Ambient Audio Environment
Atmospheric beds for biomes, scenes, and lobby music
-
Precise Timing BPM Control
Sync music to gameplay with explicit BPM and duration controls
What it does
Generate branded jingles, product video music, and ad soundtracks on demand. Test 10 audio variants of a 30-second spot with different musical moods — each one unique. Scale ad production without scaling audio costs.
How it works
Integrate the API into your creative workflow or ad platform. Generate music variants programmatically — change the mood, tempo, or genre for each ad version. Use webhook delivery to feed generated audio directly into your video editing pipeline.
Key Benefits
-
A/B Testing Multivariate
Spin up dozens of audio variants for the same ad copy
-
Branded Jingles On-Brand
Prompt-driven jingles that match brand mood and tempo
-
No Licensing Cost Saver
Skip stock-music licensing and per-track royalties
What it does
Rapidly prototype musical ideas with text descriptions. Generate 10 different mood variations in minutes — "cinematic strings, melancholic, 70 BPM" vs "electronic ambient, dreamy, 120 BPM". Use AI-generated demos as starting points or reference tracks.
How it works
Iterate quickly: adjust the prompt, BPM, or duration and regenerate. Compare variants side by side. Use generated tracks as temp music for rough cuts, as reference demos for clients, or as creative starting points for final production.
Key Benefits
-
Rapid Ideation 10x Faster
Explore directions in minutes instead of session-bookings
-
Sound Mood Boards Audio Demo
Pitch creative direction with generated audio references
-
Temp Music Film & Video
Drop AI tracks into rough cuts before final composer briefs
