# Wizper (Whisper v3) API

> Whisper v3 کی تقریر کی نقل اور ٹائم اسٹیمپ والے حصوں کے ساتھ انگریزی میں ترجمہ

`task` کے ذریعے URL سے آڈیو فائل (mp3، mp4، mpeg، mpga، m4a، wav یا webm) کی نقل تیار کرتا ہے یا اسے انگریزی میں ترجمہ کرتا ہے۔ `language` فیلڈ 99 اقدار کو سپورٹ کرتا ہے، اور خودکار شناخت بھی ممکن ہے۔ مکمل متن کے ساتھ ٹائم اسٹیمپ والے حصے واپس کرتا ہے۔ `max_segment_len` (10-29 سیکنڈ) اور `merge_chunks` حصوں کی تقسیم کو کنٹرول کرتے ہیں۔

- Model id: `wizper`
- Made by: OpenAI
- Category: Speech to Text
- Output: text
- Charged by usage (up to $1.998 per run, typical $0.009; the rest of the hold is refunded): $0.00111 / second of processing time (cheapest run $0.009 (9 API credits))
- Run: `POST https://api.doitong.com/v1/run/wizper`
- Quote: `POST https://api.doitong.com/v1/quote/wizper`
- Docs page: https://doitong.com/ur/developers/models/wizper

## Pricing

Price: **$0.00111 / second of processing time**. Charged by actual usage at $0.00111 / second of processing time: up to $1.998 per run (the quote gives the maximum for your input), the rest is refunded automatically after the run. A typical run costs $0.009.

The full example input below holds up to $1.998 = 1998 API credits (up to 1800 s of processing time × $0.00111) when it starts; a typical run costs $0.009 (9 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/wizper` 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 |  |  | ٹرانسکرپشن ان پٹ، جو mp3، mp4، mpeg، mpga، m4a، wav یا webm فارمیٹ کی آڈیو فائل کے URL کے طور پر فراہم کیا جاتا ہے۔ |
| `task` |  | enum (string) | no | `transcribe` | `transcribe`, `translate` | آڈیو پروسیسنگ ٹاسک: transcribe یا translate منتخب کریں۔ |
| `language` |  | enum (string) \| null | no | `en` | `af`, `am`, `ar`, `as`, `az`, `ba`, `be`, `bg`, `bn`, `bo`, `br`, `bs`, `ca`, `cs`, `cy`, `da`, `de`, `el`, `en`, `es`, `et`, `eu`, `fa`, `fi`, `fo`, `fr`, `gl`, `gu`, `ha`, `haw`, `he`, `hi`, `hr`, `ht`, `hu`, `hy`, `id`, `is`, `it`, `ja`, `jw`, `ka`, `kk`, `km`, `kn`, `ko`, `la`, `lb`, `ln`, `lo`, `lt`, `lv`, `mg`, `mi`, `mk`, `ml`, `mn`, `mr`, `ms`, `mt`, `my`, `ne`, `nl`, `nn`, `no`, `oc`, `pa`, `pl`, `ps`, `pt`, `ro`, `ru`, `sa`, `sd`, `si`, `sk`, `sl`, `sn`, `so`, `sq`, `sr`, `su`, `sv`, `sw`, `ta`, `te`, `tg`, `th`, `tk`, `tl`, `tr`, `tt`, `uk`, `ur`, `uz`, `vi`, `yi`, `yo`, `zh` | آڈیو زبان کا انتخاب، جس میں `None` طویل inference وقت کی قیمت پر خودکار شناخت کی درخواست کرتا ہے۔ translate ٹاسک کے لیے انگریزی ہمیشہ ترجمے کی ہدف زبان ہے، اس لیے یہ زبان کا انتخاب آؤٹ پٹ زبان تبدیل نہیں کرتا۔ |
| `chunk_level` |  | string | no | `segment` |  | واپس کیے جانے والے chunks کی granulariy۔ |
| `max_segment_len` |  | integer | no | `29` | 10 – 29 | تقسیم ہونے سے پہلے تقریری segment کی زیادہ سے زیادہ لمبائی، سیکنڈ میں۔ |
| `merge_chunks` |  | boolean | no | `true` |  | مسلسل chunks کو ملانے کا کنٹرول، جو صرف اس صورت میں merge کی اجازت دیتا ہے جب نتیجے میں بننے والے segment کا دورانیہ max_segment_len سے زیادہ نہ ہو۔ |
| `version` |  | string | no | `3` |  | Whisper large فیملی میں ورژن کا انتخاب؛ ان ماڈلز کے ذریعے کوئی دوسرا Whisper variant استعمال نہیں ہوتا۔ |

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`.

## Example input

Required parameters only:

```json
{
  "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

A fuller example:

```json
{
  "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

## 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/wizper?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }'

# 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/wizper?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }),
});
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 = {
    "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/wizper", 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": "wizper",
      "input": {
        "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
      },
      "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.
