# Mureka 9.5 Song Generation API

> Bumubuo ng mga kantang may boses mula sa prompt o liriko, na may mga kontrol sa estilo, boses at melodiya

Gamitin ang `lyrics` (hanggang 5000 character) para sa lyrics-to-song, o `prompt` (hanggang 2000) at `styles` para sa prompt-to-song. Kasama sa mga opsyon ang `gender`, `reference_id`, `vocal_id` at `melody_id`. Saklaw ng listahan ng `model` ang mureka-7.6, mureka-o2, mureka-8, mureka-9 at mureka-9.5 (default). Nagbabalik ito ng audio, duration at `song_id`.

- Model id: `mureka/api/generate/song`
- Made by: Mureka
- Category: Text to Music
- Output: audio
- Price per run: from $0.45 / run (cheapest run $0.45 (450 API credits))
- Run: `POST https://api.doitong.com/v1/run/mureka/api/generate/song`
- Quote: `POST https://api.doitong.com/v1/quote/mureka/api/generate/song`
- Docs page: https://doitong.com/fil/developers/models/mureka/api/generate/song

## Pricing

Price: **from $0.45 / run** (the lowest tier; the quote prices your exact input). Price per run: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

Price by tier:

- mureka-7.6: $0.45 / run
- mureka-o2: $0.45 / run
- mureka-8: $0.45 / run
- mureka-9: $0.45 / run
- mureka-9.5: $0.75 / run

The full example input below costs $0.75 = 750 API credits (1 run × $0.75 (mureka-9.5)).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/mureka/api/generate/song` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `model` |  | enum (string) | no | `mureka-9.5` | `mureka-7.6`, `mureka-o2`, `mureka-8`, `mureka-9`, `mureka-9.5` | Modelo na gagamitin sa pagbuo ng kanta. |
| `lyrics` |  | string \| null | no |  | 1 – 5000 characters | Tekstong aawitin para sa pagbuo ng kanta mula sa lyrics, na may maximum na haba na 5,000 character. Para sa pagbuo ng kanta mula sa prompt, magbigay ng prompt sa halip na lyrics. |
| `styles` |  | array of enum (string) \| null | no |  | ≥ 1 items | Pagpili ng genre na available lamang sa pagbuo ng kanta mula sa prompt nang walang lyrics; pumili ng isa o higit pang genre ng musika. |
| `prompt` |  | string \| null | no |  | 1 – 2000 characters | Deskripsyon ng kanta na nag-iiba ang gamit depende kung may ibinigay na lyrics: kinokontrol nito ang estilo ng musika kasama ng lyrics at kinakailangan kapag walang lyrics. Ilarawan ang nais na kanta, kabilang ang mood, mga instrumento, at vocal. |
| `gender` |  | enum (string) \| null | no |  | `female`, `male` | Kagustuhan sa kasarian ng vocal para sa pagbuo ng kanta mula sa lyrics, na ginagamit lamang kapag walang naka-upload o naka-clone na boses na pumapalit dito. |
| `reference_id` |  | string \| null | no |  | ≥ 1 characters | Identifier ng reference music na nakuha mula sa /files/upload gamit ang purpose='reference'. |
| `vocal_id` |  | string \| null | no |  | ≥ 1 characters | Identifier ng boses na nakuha mula sa /voice/clone. |
| `melody_id` |  | string \| null | no |  | ≥ 1 characters | Identifier ng melody na gagamitin nang walang prompt, reference_id, o vocal_id. Kunin ito sa pamamagitan ng /files/upload gamit ang purpose='melody'. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Maaaring luwagan ang screening sa pamamagitan ng pagtatakda ng false, kung awtorisado ang tumatawag. |

## Example input

Required parameters only:

```json
{}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/mureka/api/generate/song?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/mureka/api/generate/song?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/mureka/api/generate/song", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "mureka/api/generate/song",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
