# Wan-2.1 LoRA Trainer · T2V API

> آموزش‌دهنده LoRA برای مدل کوچک‌تر Wan 2.1 text-to-video 1.3B، از آرشیو zip تصاویر یا ویدئوها

برای مدل Wan 2.1 text-to-video 1.3B از آرشیو zip در `training_data_url` یک LoRA آموزش می‌دهد؛ آرشیو می‌تواند فایل‌های متنی کپشن داشته باشد. `number_of_steps` را بین 100 و 20000 تنظیم و `learning_rate` را تنظیم کنید. `trigger_phrase` اختیاری است و `auto_scale_input` ویدئو را به 81 فریم با نرخ 16fps تبدیل می‌کند. وزن‌های LoRA و فایل پیکربندی را برمی‌گرداند.

## Pricing

Price: **$0.005 / step**. Billed per training step (`number_of_steps`).

The full example input below costs $2.00 = 2000 API credits (400 steps × 5 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/wan-trainer/t2v` 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 |
|---|---|---|---|---|---|---|
| `training_data_url` |  | string | yes |  |  | URL بایگانی ZIP آموزشی برای تصاویر دارای سبک یکدست، با امکان افزودن فایل‌های متنی کپشن که نامشان با فایل تصویر یا ویدیوی متناظر یکسان است. هدف، گنجاندن حداقل 10 تصویر، ویدیو یا ترکیبی از هر دو است؛ مجموعه‌های بزرگ‌تر ترجیح داده می‌شوند. |
| `number_of_steps` |  | integer | no | `400` | 100 – 20,000 | تعداد کل گام‌های آموزش. |
| `learning_rate` |  | number | no | `0.0002` | 0.000001 – 1 | تنظیم نرخ یادگیری: افزایش نرخ می‌تواند آموزش را سریع‌تر کند، اما خطر بیش‌برازش را نیز افزایش می‌دهد. |
| `trigger_phrase` |  | string | no | `` |  | عبارتی که مدل را به تولید تصویر وادار می‌کند. |
| `auto_scale_input` |  | boolean | no | `false` |  | تعیین می‌کند آیا ویدیوی ورودی به‌طور خودکار مقیاس‌گذاری شود یا نه: مقدار true طول آن را به 81 فریم و نرخ فریم آن را به 16 fps تنظیم می‌کند. |

## Example input

Required parameters only:

```json
{
  "training_data_url": "https://example.com/your-file.zip"
}
```

A fuller example:

```json
{
  "training_data_url": "https://example.com/your-file.zip"
}
```

## 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/wan-trainer/t2v?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "training_data_url": "https://example.com/your-file.zip"
  }'

# 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/wan-trainer/t2v?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "training_data_url": "https://example.com/your-file.zip"
  }),
});
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 = {
    "training_data_url": "https://example.com/your-file.zip",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/wan-trainer/t2v", 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": "wan-trainer/t2v",
      "input": {
        "training_data_url": "https://example.com/your-file.zip"
      },
      "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.
