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' => 'clean corporate background track, commercial-safe, 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 royalty-free

Stock music libraries charge per track, per seat, or per stream, and the license terms change. Tracking which clip is cleared for which project becomes its own job. You need original music you fully own, generated at the moment you need it, without a licensing department.

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