Node.js quick start

Set MUSICAPI_KEY, paste this, and run it. It is a real request against the live API, prompted for background music.

ts
// 1) start a generation
const res = await fetch("https://api.musicapi.ai/api/v1/sonic/create", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.MUSICAPI_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    custom_mode: false,
    mv: "sonic-v5",
    gpt_description_prompt: "soft ambient background bed, unobtrusive, no vocals",
  }),
})
const { task_id } = await res.json()

// 2) poll GET /api/v1/sonic/task/{task_id} until data[0].audio_url is set

Full Node.js setup (SDK, polling helper, error handling) is on the Node.js music API guide.

Why teams use it for background

Background music has to sit under something else: a voiceover, a UI, a video. A library track rarely fits the exact mood or length, so editors spend time hunting and trimming. You need a bed that matches the brief and does not fight the foreground.

More on this use case, including output and licensing details, on the Background Music API page.

FAQ

How do I generate background music from Node.js?

POST a prompt to https://api.musicapi.ai/api/v1/sonic/create from Node.js with your API key, then poll the returned task_id at /api/v1/sonic/task/{task_id} until the audio URL is ready. The snippet above is a complete starting point.

What does it cost?

Each music generation is 15 credits (2 songs). New accounts get free signup credits with no card, then it is pay-as-you-go. See the per-operation table at musicapi.ai/pricing#credit-costs.

Where is the full Node.js setup?

This page is the background-focused quick start. The complete Node.js integration (install, polling helper, error handling) is at musicapi.ai/nodejs-music-api.
