# OpenRouter [Audio] API

> Varianta da gateway LLM che elavura ina datoteca audio per transcripziun u analisa, cun in prompt

Accepta ina datoteca audio via `audio_url` ensemen cun in `prompt` ed in `model` obligatoric. Ils formats enumerads èn wav, mp3, aiff, aac, ogg, flac e m4a. `system_prompt`, `temperature`, `max_tokens`, `reasoning` e parameters da tschertga web facultativs èn disponibels. Retorna output da text e l’utilisaziun da tokens.

- Model id: `openrouter/router/audio`
- Made by: OpenRouter
- Category: LLM
- Output: text
- Charged by usage (up to $1.858 per run, typical $0.019; the rest of the hold is refunded): $0.01 / usage unit (cheapest run $0.019 (19 API credits))
- Run: `POST https://api.doitong.ru/v1/run/openrouter/router/audio`
- Quote: `POST https://api.doitong.ru/v1/quote/openrouter/router/audio`
- Docs page: https://doitong.com/rm/developers/models/openrouter/router/audio

## Pricing

Price: **$0.01 / usage unit**. Charged by actual usage at $0.01 / usage unit: up to $1.858 per run (the quote gives the maximum for your input), the rest is refunded automatically after the run. A typical run costs $0.019.

The full example input below holds up to $1.858 = 1858 API credits (up to 185.7946 units × $0.01) when it starts; a typical run costs $0.019 (19 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). This model is charged by usage: `POST https://api.doitong.ru/v1/quote/openrouter/router/audio` with the same JSON body returns the most the run can cost for that input (`credits`, debited when the run starts); after the run you pay the usage the model reports and the rest is refunded automatically. An input whose maximum would exceed the per-run limit is refused with 422. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `audio_url` | `audio` | string (audio URL) | yes |  |  | Input audio per l’elavuraziun, specifitgà cun URL u URI da datas. Formats acceptads èn m4a, flac, ogg, aac, aiff, mp3 e wav. |
| `prompt` |  | string | yes |  |  | Prompt che dirigescha l’elavuraziun audio. |
| `system_prompt` |  | string \| null | no |  |  | Prompt dal sistem che furnescha al model instrucziuns u context. |
| `model` |  | string | yes |  |  | Num che identifitgescha il model da exequir. |
| `reasoning` |  | boolean | no | `false` |  | Inditgescha sch’il raschunament duai vegnir inclus en la resposta finala. |
| `temperature` |  | number | no | `1` | 0 – 2 | Controlla da la variabladad da la resposta, cun 0 che garantescha la medema resposta sch’il input resta invarià. Augmentar la valur allontanescha las respostas da respostas prevediblas e tipicas vers dapli diversitad e respostas pli raras. |
| `max_tokens` |  | integer \| null | no |  | ≥ 1 | Limita il dumber da tokens generads da la resposta ad ina valur betg pli gronda che la lunghezza dal context minus la lunghezza dal prompt. La generaziun na po betg surpassar questa limita. |

Definescha ina maxima exacta da 1 fin 100,000 caracters; la tschertga nativa ignora questa configuraziun. |
| `web_search_options.allowed_domains` |  | array of string \| null | no |  |  | Allowlist da domens per Exa e la gronda part dals providers nativs, che restrenscha ils resultats als domens inditgads. La tschertga nativa da Google na la sustegna betg. |
| `web_search_options.excluded_domains` |  | array of string \| null | no |  |  | Glista d’exclusiun da domens per tschertgas Exa e providers nativs cumpatibels; las tschertgas nativas da Google e OpenAI na pon betg applicar questa glista. Resultats da domens inditgads vegnan exclus. |
| `web_search_options.user_location` |  | object {type, city, region, country, timezone} \| null | no |  |  | Lieu approximativ da l’utilisader che influenzescha geograficamain ils resultats da la tschertga nativa; Exa na utilisescha betg quest’infurmaziun. |
| `web_search_options.user_location.type` |  | string | no | `approximate` |  | Classificaziun dal lieu; l’unica valur sustegnida è 'approximate'. |

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
  "model": "google/gemini-3.8-flash"
}
```

## 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/openrouter/router/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",
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
    "model": "google/gemini-3.8-flash"
  }'

# 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 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/openrouter/router/audio?wait=20", {

  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/openrouter/router/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": "openrouter/router/audio",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
        "model": "google/gemini-3.8-flash"
      },
      "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.
