## Autentikasi

<ParamField header="Authorization" type="string" required>
  Semua endpoint memerlukan autentikasi menggunakan Bearer Token

  Mendapatkan API Key:

  Kunjungi [halaman pengelolaan API Key](https://apimart.ai/keys) untuk mendapatkan API Key Anda

  Tambahkan ke header permintaan saat digunakan:

  ```
  Authorization: Bearer YOUR_API_KEY
  ```
</ParamField>

## Parameter Permintaan

<ParamField body="model" type="string" required>
  Nama model, **selalu isi `"flowmusic"`** (tidak peka huruf besar/kecil)
</ParamField>

<ParamField body="clip_id" type="string" required>
  clip\_id musik yang akan diunduh, berasal dari `result.music[].clip_id` tugas yang telah berhasil
</ParamField>

<ParamField body="format" type="string" required>
  Format unduhan

  Nilai yang tersedia:

  * `mp3` - kompresi lossy, ukuran kecil
  * `wav` - lossless, cocok untuk pascaproduksi
</ParamField>

## Respons

<ResponseField name="code" type="integer">
  Kode status respons, bernilai 200 jika berhasil
</ResponseField>

<ResponseField name="data" type="array">
  Array data yang dikembalikan

  <Expandable title="Elemen array">
    <ResponseField name="status" type="string">
      Status tugas, bernilai `submitted` saat pengajuan awal
    </ResponseField>

    <ResponseField name="task_id" type="string">
      Pengidentifikasi unik tugas, digunakan untuk memeriksa status dan hasil tugas
    </ResponseField>
  </Expandable>
</ResponseField>

## Skenario Penggunaan

### Skenario 1: Mengekspor wav lossless

```json theme={null}
{
  "model": "flowmusic",
  "clip_id": "abc123-def456",
  "format": "wav"
}
```

<Note>
  **Memeriksa hasil tugas**

  Pengunduhan audio adalah tugas asinkron; setelah diajukan, `task_id` akan dikembalikan. Gunakan endpoint [Mendapatkan Status Tugas](./query) untuk memeriksa progres dan hasil pembuatan. Hasilnya selalu ada di `result.music[0].audio_url` (`url` bernilai sama); field `format` / `mime_type` menandakan format sebenarnya.
</Note>

## Contoh Hasil Tugas Selesai

**Contoh respons kueri** (`GET /v1/music/tasks/{task_id}`):

```json theme={null}
{
  "code": 200,
  "data": {
    "id": "task_01KWXVD3FPYYQPJ2N87XXE5NQG",
    "status": "completed",
    "progress": 100,
    "created": 1783413247,
    "completed": 1783413296,
    "actual_time": 49,
    "cost": 0.016,
    "credits_cost": 0.16,
    "result": {
      "music": [
        {
          "clip_id": "a41aade4-993e-4d28-b56f-d97e7ef7167c",
          "format": "wav",
          "mime_type": "audio/wav",
