PHP quick start

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

php

<?php
$client = new GuzzleHttp\Client();

// 1) start a generation
$res = $client->post('https://api.musicapi.ai/api/v1/sonic/create', [
    'headers' => ['Authorization' => 'Bearer ' . getenv('MUSICAPI_KEY')],
    'json' => [
        'custom_mode' => false,
        'mv' => 'sonic-v5',
        'gpt_description_prompt' => 'soft ambient background bed, unobtrusive, no vocals',
    ],
]);
$taskId = json_decode($res->getBody(), true)['task_id'];

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

Full PHP setup (SDK, polling helper, error handling) is on the PHP 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 PHP?

POST a prompt to https://api.musicapi.ai/api/v1/sonic/create from PHP 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.
