# suno-generate-mashup

> Create a mashup using 1-5 audio tracks.

## Overview

- **Endpoint**: `POST https://api.muapi.ai/api/v1/suno-generate-mashup`
- **Model ID**: `suno-generate-mashup`
- **Category**: text to audio
- **Variant**: Suno Mashup
- **Family**: suno
- **Cost**: 0.09 credits per call (some models compute cost dynamically based on params)

## API Usage

MuApi uses a **submit-then-poll** pattern: submit a job, get a `request_id`, then poll the predictions endpoint until `status` is `completed`. Optionally pass `?webhook=YOUR_URL` on the submit call to receive a POST callback when the job finishes (skip polling).

**Authentication**: send your MuApi key in the `x-api-key` header. Get one at https://muapi.ai/access-keys.

### 1. Submit a job

```http
POST https://api.muapi.ai/api/v1/suno-generate-mashup
Content-Type: application/json
x-api-key: YOUR_API_KEY
```

**Minimum (required only):**

```json
{
  "audios_list": []
}
```

**Full example (all params):**

```json
{
  "audios_list": [],
  "prompt": "<prompt>",
  "style": "<style>",
  "instrumental": true,
  "model": "V5",
  "vocal_gender": "male",
  "style_weight": 0.65,
  "weirdness_constraint": 0.65,
  "audio_weight": 0.65,
  "title": "New Mashup"
}
```

**Response:**

```json
{
  "request_id": "abc123",
  "status": "processing"
}
```

### 2. Poll for the result

```http
GET https://api.muapi.ai/api/v1/predictions/{request_id}/result
x-api-key: YOUR_API_KEY
```

Possible `status` values: `queued`, `pending`, `processing`, `completed`, `failed`, `cancelled`. Poll every 2-5 seconds until terminal. When `completed`, the result URLs are in the `outputs` array.

**Example response when `completed`:**

```json
{
  "id": "abc123",
  "status": "completed",
  "outputs": [
    "https://cdn.muapi.ai/.../output.png"
  ],
  "urls": {
    "get": "https://api.muapi.ai/api/v1/predictions/abc123/result"
  },
  "created_at": "2026-05-08T12:34:56Z",
  "has_nsfw_contents": []
}
```

### cURL

```bash
# 1. Submit
REQUEST_ID=$(curl -s -X POST https://api.muapi.ai/api/v1/suno-generate-mashup \
  -H "x-api-key: $MUAPI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"audios_list":[]}' | jq -r .request_id)

# 2. Poll until completed
while :; do
  RESP=$(curl -s https://api.muapi.ai/api/v1/predictions/$REQUEST_ID/result -H "x-api-key: $MUAPI_API_KEY")
  STATUS=$(echo "$RESP" | jq -r .status)
  [ "$STATUS" = "completed" ] && echo "$RESP" | jq .outputs && break
  [ "$STATUS" = "failed" ] && echo "$RESP" && exit 1
  sleep 3
done
```

### Python

```python
import os, time, requests

API = "https://api.muapi.ai/api/v1"
headers = {"x-api-key": os.environ["MUAPI_API_KEY"]}

r = requests.post(f"{API}/suno-generate-mashup", headers=headers, json={"audios_list":[]})
request_id = r.json()["request_id"]

while True:
    res = requests.get(f"{API}/predictions/{request_id}/result", headers=headers).json()
    if res["status"] == "completed":
        print(res["outputs"]); break
    if res["status"] == "failed":
        raise RuntimeError(res.get("error")); 
    time.sleep(3)
```

## Input Schema

The API accepts the following input parameters:

- **`audios_list`** (`array`, _required_):
  Upload up to 2 audio files to mashup music from multiple audio tracks.

- **`prompt`** (`string`, _optional_):
  Creative guidance

- **`style`** (`string`, _optional_):
  Mashup style

- **`instrumental`** (`boolean`, _optional_):
  If true: Only style is required else style, and prompt are required (with prompt used as the exact lyrics)
  - Default: `true`

- **`model`** (`string`, _optional_):
  The AI model version to use.
  - Default: `"V5"`
  - Options: `"V4"`, `"V4_5"`, `"V4_5PLUS"`, `"V5"`

- **`vocal_gender`** (`string`, _optional_):
  Vocal gender preference.
  - Default: `"male"`
  - Options: `"male"`, `"female"`

- **`style_weight`** (`int`, _optional_):
  Strength of style adherence (0-1).
  - Default: `0.65`

- **`weirdness_constraint`** (`int`, _optional_):
  Experimental deviation (0-1).
  - Default: `0.65`

- **`audio_weight`** (`int`, _optional_):
  Balance weight (0-1).
  - Default: `0.65`

- **`title`** (`string`, _optional_):
  Mashup title
  - Default: `"New Mashup"`

## Output Schema

The polling endpoint returns the following fields:

- **`id`** (`string`): The request ID.
- **`status`** (`string`): One of `queued`, `pending`, `processing`, `completed`, `failed`, `cancelled`.
- **`outputs`** (`array`): URLs to generated images/videos/audio. Empty until `status` is `completed`.
- **`urls.get`** (`string`): Self-link to re-fetch this prediction.
- **`error`** (`string` | `null`): Error message if `status` is `failed`.
- **`created_at`** (`string`): ISO-8601 timestamp of when the request was created.
- **`has_nsfw_contents`** (`array of boolean`): Per-output NSFW detection flags.

## Webhooks (optional)

Append `?webhook=https://your-server/path` to the submit URL. When the job reaches a terminal state, MuApi will POST the same shape as the polling response to your URL — no polling needed.

## Agent Integration

MuApi ships an MCP server and CLI so agents (Claude Code, Cursor, custom) can call this endpoint without writing HTTP code:

```bash
# Install the CLI
npm install -g muapi-cli

# Authenticate once
muapi auth login

# Expose all MuApi models as MCP tools to your agent
muapi mcp serve
```

The MCP server exposes tools that wrap submit + poll for every model, including `suno-generate-mashup`. See `muapi --help` for category-specific shortcuts (`muapi image generate`, `muapi video from-image`, etc.).
