# OpenRouter [Audio] API

> Varian gateway LLM yang memproses file audio untuk transkripsi atau analisis, dengan prompt

Menerima file audio melalui `audio_url` bersama `prompt` dan `model` wajib. Format yang tercantum adalah wav, mp3, aiff, aac, ogg, flac, dan m4a. Pengaturan opsional `system_prompt`, `temperature`, `max_tokens`, `reasoning`, dan pencarian web tersedia. Mengembalikan output teks dan penggunaan token.

- 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.com/v1/run/openrouter/router/audio`
- Quote: `POST https://api.doitong.com/v1/quote/openrouter/router/audio`
- Docs page: https://doitong.com/id/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.com/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 untuk diproses, yang ditentukan melalui URL atau URI data. Format yang diterima adalah m4a, flac, ogg, aac, aiff, mp3, dan wav. |
| `prompt` |  | string | yes |  |  | Prompt yang mengarahkan pemrosesan audio. |
| `system_prompt` |  | string \| null | no |  |  | Prompt sistem yang memberikan instruksi atau konteks kepada model. |
| `model` |  | string | yes |  |  | Nama yang mengidentifikasi model yang akan dijalankan. |
| `reasoning` |  | boolean | no | `false` |  | Apakah penalaran disertakan dalam respons akhir. |
| `temperature` |  | number | no | `1` | 0 – 2 | Kontrol variasi respons, dengan 0 menjamin jawaban yang sama setiap kali input tidak berubah. Meningkatkan nilainya menggeser respons dari jawaban yang dapat diprediksi dan umum menuju jawaban yang lebih beragam dan tidak lazim. |
| `max_tokens` |  | integer \| null | no |  | ≥ 1 | Batasi jumlah token yang dihasilkan dalam respons ke nilai yang tidak lebih besar dari panjang konteks dikurangi panjang prompt. Pembuatan tidak dapat melebihi batas yang ditentukan. |
| `enable_web_search` |  | boolean | no | `false` |  | Sakelar akses web yang memungkinkan model memilih apakah dan kapan harus mencari, termasuk beberapa pencarian dalam satu permintaan. Pencarian menggunakan alat pencarian web sisi server OpenRouter untuk memperoleh informasi waktu nyata. |
| `web_search_options` |  | object {engine, max_results, max_uses, max_total_results, search_context_size, max_characters, allowed_domains, excluded_domains, user_location} \| null | no |  |  | Konfigurasi pencarian web, termasuk pilihan mesin, batas hasil, dan pemfilteran domain. Hanya digunakan saat enable_web_search adalah true. |
| `web_search_options.engine` |  | enum (string) | no | `auto` | `auto`, `native`, `exa` | Pilihan mesin pencari: 'auto' dan 'native' sama-sama beralih ke Exa saat pencarian native tidak tersedia. 'auto' menggunakan pencarian native penyedia yang tersedia; 'native' memprioritaskan pencarian bawaan dari OpenAI, Anthropic, Google, xAI, atau Perplexity. Untuk menggunakan API pencarian Exa secara eksklusif, pilih 'exa'. |
| `web_search_options.max_results` |  | integer \| null | no |  | 1 – 25 | Batas hasil untuk setiap panggilan pencarian Exa, dari 1 hingga 25, dengan bawaan 5. Pencarian penyedia native mengabaikan pengaturan ini. |
| `web_search_options.max_uses` |  | integer \| null | no |  | ≥ 1 | Batas pencarian per permintaan, diteruskan ke Anthropic untuk pencarian native tetapi diabaikan oleh penyedia native lainnya. Panggilan yang melampaui batas menerima hasil error dan tidak dijalankan. |
| `web_search_options.max_total_results` |  | integer \| null | no |  | ≥ 1 | Batas hasil gabungan untuk semua pencarian dalam satu permintaan. |
| `web_search_options.search_context_size` |  | enum (string) \| null | no |  | `low`, `medium`, `high` | Jumlah pengambilan per hasil untuk Exa, digantikan oleh max_characters jika keduanya diberikan dan diabaikan untuk pencarian penyedia native. Pilih low untuk 5K karakter, medium untuk 15K, atau high untuk 30K; jika tidak ditentukan, Exa menyesuaikan jumlahnya menjadi sekitar 2–4K per hasil. |
| `web_search_options.max_characters` |  | integer \| null | no |  | 1 – 100,000 | Batas karakter konten per hasil untuk Exa, yang menggantikan search_context_size jika keduanya diberikan. Tetapkan maksimum tepat dari 1 hingga 100.000 karakter; pencarian penyedia native mengabaikan pengaturan ini. |
| `web_search_options.allowed_domains` |  | array of string \| null | no |  |  | Allowlist domain untuk Exa dan sebagian besar penyedia pencarian native, yang membatasi hasil ke domain yang tercantum. Pencarian native Google tidak mendukungnya. |
| `web_search_options.excluded_domains` |  | array of string \| null | no |  |  | Daftar pengecualian domain untuk pencarian Exa dan penyedia native yang kompatibel; pencarian native Google dan OpenAI tidak dapat menerapkan daftar ini. Hasil yang berasal dari domain tercantum dikecualikan. |
| `web_search_options.user_location` |  | object {type, city, region, country, timezone} \| null | no |  |  | Lokasi pengguna perkiraan yang memengaruhi hasil pencarian native secara geografis; Exa tidak menggunakan informasi ini. |
| `web_search_options.user_location.type` |  | string | no | `approximate` |  | Klasifikasi lokasi; satu-satunya nilai yang didukung adalah 'approximate'. |
| `web_search_options.user_location.city` |  | string \| null | no |  |  | Nama kota, seperti 'San Francisco'. |
| `web_search_options.user_location.region` |  | string \| null | no |  |  | Nama negara bagian atau wilayah, seperti 'California'. |
| `web_search_options.user_location.country` |  | string \| null | no |  |  | Pengenal negara yang dinyatakan sebagai dua huruf, seperti 'US'. |
| `web_search_options.user_location.timezone` |  | string \| null | no |  |  | Pengenal zona waktu dalam notasi IANA, seperti 'America/Los_Angeles'. |

File parameters (`audio`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## 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/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.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

### 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",
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",

}

# 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.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": "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.
