# Mirelo SFX2.0 · Text to Audio API

> Maisíochtaí fuaime ó chur síos téacs, le leid dhiúltach, fad agus roinnt samplaí

Gineann sé maisíochtaí fuaime ó `prompt` suas le 2000 carachtar, le `negative_prompt` chun fuaimeanna a eisiamh. Raontaíonn `duration` ó 0.1 go 600 soicind (réamhshocrú 30), agus cruthaíonn `num_samples` 1 go 4 athrú, gach ceann lena shíol féin. Is é wav, mp3, aac nó flac formáid an aschuir trí `upload_audio_format`, le ráta giotán roghnach do mp3 agus aac.

## Pricing

Price: **$0.01 / second of output audio**. Price per second of your output audio: 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.

The full example input below costs $0.60 = 600 API credits (60 s output audio × $0.01).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.ru/v1/quote/mirelo-ai/sfx2.0/text-to-audio` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | 1 – 2000 characters | Cur síos ar an maisíocht fuaime inmhianaithe. |
| `negative_prompt` |  | string \| null | no |  | ≤ 1000 characters | Fuaimeanna atá le heisiamh ón aschur. |
| `duration` |  | number | no | `30` | 0.1 – 600 | Fad fuaime iarrtha, tomhaiste ina soicindí, a chaithfidh luí laistigh den uasmhéid sonrach don imscaradh le haghaidh text-to-SFX. |
| `seed` |  | integer \| null | no |  | -1 – 9,223,372,036,854,776,000 | Síol an tsampla thosaigh; úsáidtear síol randamach le haghaidh -1 nó nuair a fhágtar ar lár é. |
| `num_samples` |  | integer | no | `2` | 1 – 4 | Líon samplaí le haghaidh giniúna laistigh d'aon phas tosaigh bhaiste amháin. |
| `upload_audio_format` |  | enum (string) | no | `wav` | `wav`, `mp3`, `aac`, `flac` | Formáid a úsáidtear do gach comhad fuaime. |
| `upload_audio_bitrate_kbps` |  | integer \| null | no |  | 32 – 320 | Sárú ráta giotán uaslódála in kbps, diúltaithe nuair atá upload_audio_format gan chailliúint; má fhágtar gan socrú é, coinnítear LAME V0 VBR do mp3 nó sprioc 256 kbps do aac. I gcás mp3, roghnaigh ráta tairiseach cruinn ó 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320. I gcás aac, sonraíonn luachanna ó 32 go 256 sprioc ionchódóra seachas ráta ráthaithe, mar sin d'fhéadfadh fuaim mhona nó tanaí titim faoina bhun. |

## Example input

Required parameters only:

```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.ru/v1/run/mirelo-ai/sfx2.0/text-to-audio?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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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/mirelo-ai/sfx2.0/text-to-audio?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.ru/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/mirelo-ai/sfx2.0/text-to-audio", 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.ru/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": "mirelo-ai/sfx2.0/text-to-audio",
      "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.
