## Authentication

Scenario API uses HTTP Basic Auth. Encode your credentials in Base64 and pass them as the `Authorization` header.

```

- **API_KEY** and **API_SECRET** are found in your [Scenario Project Settings](https://app.scenario.com/team&tab=project_api_keys) under API Keys.
- In shell: `$(echo -n '<API_KEY>:<API_SECRET>' | base64)`
- In JavaScript: `btoa("<API_KEY>:<API_SECRET>")`
- In Python: `base64.b64encode(f"{api_key}:{api_secret}".encode()).decode()`

## Generate

**Endpoint:** `POST https://api.cloud.scenario.com/v1/generate/custom/model_minimax-music-2-6`

### Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `lyrics` | string | - | `` | Lyrics for vocal tracks (up to 3,500 characters). Omit for instrumental mode, or leave empty and enable 'Auto lyrics' to generate lyrics from the style prompt. Use \n between lines and \n\n for pauses. Structure tags include [Intro], [Verse], [Pre Chorus], [Chorus], [Hook], [Drop], [Bridge], [Solo], [Build Up], [Inst], [Interlude], [Break], [Transition], [Outro], and more. |
| `prompt` | string | yes | - | Genre, mood, tempo (e.g. BPM), key, vocal style, and instrumentation (up to 2,000 characters). For instrumental mode, this is the main instruction. |
| `isInstrumental` | boolean | - | `false` | When true, generates music without vocals. Use the style prompt only; lyrics are not required. |
| `lyricsOptimizer` | boolean | - | `false` | When true and lyrics are empty, the model generates lyrics from the style prompt. |
| `sampleRate` | number | - | `44100` | Audio sample rate for the generated music |
| `bitrate` | number | - | `256000` | Bitrate for the generated music |

## Retrieve Results

After submitting a generation request, you receive a `jobId`. Poll the job status endpoint until the job completes.

**Endpoint:** `GET https://api.cloud.scenario.com/v1/jobs/{jobId}`

**Headers:**
```
Authorization: Basic base64("<API_KEY>:<API_SECRET>")
```

Poll until `job.status` is `"success"`. The generated asset IDs are in `job.metadata.assetIds`.

**Example response:**
```json
{
  "job": {
    "jobId": "job_abc123",
    "status": "success",
    "metadata": {
      "assetIds": [
        "asset_abc123"
      ]
    }
  }
}
```

> **Important:** Generated asset URLs are **temporary** and expire after a short period. Download and store any images you wish to keep before the URL expires. More info: [Content Delivery Network (CDN)](https://docs.scenario.com/docs/content-delivery-network-cdn).
