Song Cover APIAI Covers & Style Re-renders
Re-render any AI clip into a new genre, mood, or instrumentation with one REST call. Pass a source clip and tags, generate a cover, poll for the result, and download — with API keys, free trial credits, pricing, webhooks, and production-ready docs.
What is the Song Cover API?
Cover keeps the musical idea of an existing clip but re-renders it with new tags — a different genre, mood, or instrumentation. It runs through the generation endpoint with a task_type of cover_music, so it inherits the same auth, polling, and download flow as the rest of the API.
- Style-Steered
Drive the cover with
tagslike "lo-fi, acoustic, mellow" to swap genre, mood, or instrumentation.- One REST Endpoint
Same
/sonic/createendpoint and bearer auth — just set the task type tocover_music.- Keeps the Idea
The cover preserves the source song's core idea while applying your requested style.
API Examples
Create a cover from a source clip, then poll the task until it's ready.

Song Cover API: Pricing, Free Access & API Keys
Developers adding AI covers usually want three answers: how to test for free, how to get an API key, and how cost scales after the prototype works.
Free trial
Use free credits to test cover, polling, and downloads before choosing a paid plan.
Pricing
Credit-based, same as generation. Estimate per-cover cost on the pricing page.
API keys
Generate a bearer token in your account, keep it server-side, and call the cover endpoint.

Frequently Asked Questions
Everything you need to know about generating covers with the API.
What is a song cover API?
A song cover API re-renders an existing AI music clip into a new style, genre, or mood while keeping the underlying musical idea. With MusicAPI you call the generation endpoint with task_type 'cover_music', the source clip id, and tags describing the new style.
How do I create an AI cover with the API?
POST to https://api.musicapi.ai/api/v1/sonic/create with task_type 'cover_music', a continue_clip_id from a prior generation, tags such as 'lo-fi, acoustic, mellow', and the model version (mv). The call returns a task_id; poll GET /api/v1/sonic/task/{id} until the cover is ready, then download.
What is the difference between cover and extend?
Both build on an existing clip via /sonic/create. Extend (task_type 'extend_music') makes the same song longer; cover (task_type 'cover_music') keeps the musical idea but re-renders it with new tags/style — a different genre, mood, or instrumentation.
How do I control the cover style?
Use the tags field to steer genre, instrumentation, and mood — for example 'lo-fi, acoustic, mellow' or 'synthwave, energetic'. The cover keeps the source idea and applies your requested style.
How much does an AI cover cost?
Cover runs on the same credit-based pricing as generation. Test with free trial credits, estimate per-task cost on the pricing page, and upgrade as volume grows. Failed upstream tasks are auto-refunded and polling task status is free.
Is cover generation synchronous or asynchronous?
Asynchronous. The create call returns a task_id immediately and the cover is produced in the background, typically within 1-3 minutes. Use polling on the task endpoint or webhooks to detect completion.
Do covers include commercial rights?
Yes, audio generated through the API comes with commercial rights included. You own the generated content and can use it for commercial purposes.
