# OpenRouter [Audio] API

> LLM gateway variant na nagpoproseso ng audio file para sa transcription o analysis, gamit ang prompt

Tumatanggap ng audio file sa pamamagitan ng `audio_url`, kasama ang `prompt` at kinakailangang `model`. Ang mga nakalistang format ay wav, mp3, aiff, aac, ogg, flac at m4a. Available ang opsyonal na `system_prompt`, `temperature`, `max_tokens`, `reasoning` at web search setting. Nagbabalik ito ng teksto output at token paggamit.

- 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/fil/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 |  |  | Audio input para sa pagproseso, na tinutukoy ng URL o data URI. Ang mga tinatanggap na format ay m4a, flac, ogg, aac, aiff, mp3, at wav. |
| `prompt` |  | string | yes |  |  | Prompt na gumagabay sa pagproseso ng audio. |
| `system_prompt` |  | string \| null | no |  |  | System prompt na nagbibigay sa modelo ng mga tagubilin o context. |
| `model` |  | string | yes |  |  | Pangalan na tumutukoy sa modelong tatakbuhin. |
| `reasoning` |  | boolean | no | `false` |  | Kung isasama ang reasoning sa final na tugon. |
| `temperature` |  | number | no | `1` | 0 – 2 | Kontrol sa pagkakaiba-iba ng tugon, kung saan ginagarantiyahan ng 0 ang magkaparehong sagot kapag hindi nagbago ang input. Kapag tinaasan ang value, lumalayo ang mga tugon sa predictable at karaniwang sagot patungo sa mas maraming pagkakaiba-iba at mas hindi pangkaraniwang sagot. |
| `max_tokens` |  | integer \| null | no |  | ≥ 1 | Limitahan ang bilang ng nabuong token ng tugon sa value na hindi lalampas sa haba ng context bawas haba ng prompt. Hindi lalampas ang pagbuo sa tinukoy na limitasyon. |
| `enable_web_search` |  | boolean | no | `false` |  | Toggle para sa web access na nagpapahintulot sa modelo na pumili kung at kailan maghahanap, kabilang ang maraming paghahanap sa isang kahilingan. Ginagamit ng mga paghahanap ang server-side web search tool ng OpenRouter upang kumuha ng real-time na impormasyon. |
| `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 |  |  | Configuration ng web search, kabilang ang pagpili ng engine, limitasyon ng resulta, at pag-filter ng domain. Ginagamit lamang kapag true ang enable_web_search. |
| `web_search_options.engine` |  | enum (string) | no | `auto` | `auto`, `native`, `exa` | Pagpili ng search engine: parehong nagfa-fallback sa Exa ang 'auto' at 'native' kapag hindi available ang native search. Ginagamit ng 'auto' ang available na provider-native search; mas pinipili ng 'native' ang built-in search mula sa OpenAI, Anthropic, Google, xAI, o Perplexity. Para eksklusibong gamitin ang search API ng Exa, piliin ang 'exa'. |
| `web_search_options.max_results` |  | integer \| null | no |  | 1 – 25 | Limitasyon ng resulta sa bawat tawag sa Exa search, mula 1 hanggang 25, na may default na 5. Hindi pinapansin ng native provider search ang setting na ito. |
| `web_search_options.max_uses` |  | integer \| null | no |  | ≥ 1 | Limitasyon ng search sa bawat kahilingan, ipinapasa sa Anthropic para sa native search ngunit hindi pinapansin ng ibang native provider. Nagbabalik ng error result ang mga tawag na lampas sa limitasyon at hindi tumatakbo. |
| `web_search_options.max_total_results` |  | integer \| null | no |  | ≥ 1 | Pinagsamang limitasyon ng resulta para sa lahat ng paghahanap sa isang kahilingan. |
| `web_search_options.search_context_size` |  | enum (string) \| null | no |  | `low`, `medium`, `high` | Halaga ng retrieval sa bawat resulta para sa Exa, na napapalitan ng max_characters kapag parehong ibinigay at hindi pinapansin para sa native provider search. Piliin ang low para sa 5K character, medium para sa 15K, o high para sa 30K; kapag hindi tinukoy, inaangkop ng Exa ang halaga sa humigit-kumulang 2–4K bawat resulta. |
| `web_search_options.max_characters` |  | integer \| null | no |  | 1 – 100,000 | Limitasyon ng character ng content sa bawat resulta para sa Exa, na pumapalit sa search_context_size kapag parehong ibinigay. Magtakda ng eksaktong maximum mula 1 hanggang 100,000 character; hindi pinapansin ng native provider search ang setting na ito. |
| `web_search_options.allowed_domains` |  | array of string \| null | no |  |  | Allowlist ng domain para sa Exa at karamihan ng native search provider, na naglilimita sa mga resulta sa nakalistang domain. Hindi ito sinusuportahan ng Google native search. |
| `web_search_options.excluded_domains` |  | array of string \| null | no |  |  | Listahan ng ibinubukod na domain para sa Exa search at mga katugmang native provider; hindi mailalapat ng Google at OpenAI native search ang listahang ito. Hindi isinasama ang mga resultang nagmula sa nakalistang domain. |
| `web_search_options.user_location` |  | object {type, city, region, country, timezone} \| null | no |  |  | Tinatayang lokasyon ng user na nagbibigay ng geographic bias sa mga resulta ng native search; hindi ginagamit ng Exa ang impormasyong ito. |
| `web_search_options.user_location.type` |  | string | no | `approximate` |  | Classification ng lokasyon; ang tanging suportadong value ay 'approximate'. |
| `web_search_options.user_location.city` |  | string \| null | no |  |  | Pangalan ng lungsod, gaya ng 'San Francisco'. |
| `web_search_options.user_location.region` |  | string \| null | no |  |  | Pangalan ng estado o rehiyon, gaya ng 'California'. |
| `web_search_options.user_location.country` |  | string \| null | no |  |  | Identifier ng bansa na ipinapahayag gamit ang dalawang titik, gaya ng 'US'. |
| `web_search_options.user_location.timezone` |  | string \| null | no |  |  | Identifier ng timezone sa IANA notation, gaya ng '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" \

### 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.
