# Wan-2.1 LoRA Trainer · T2V API

> Kifunzaji cha LoRA cha modeli ndogo ya Wan 2.1 text-to-video 1.3B, kutoka kwenye zipu ya picha au video

Hufunza LoRA ya Wan 2.1 text-to-video 1.3B kutoka kwenye jalada la zip kwenye `training_data_url`, ambalo linaweza kujumuisha maelezo kama faili za maandishi. Weka `number_of_steps` kati ya 100 na 20000 na rekebisha `learning_rate`. `trigger_phrase` ni ya hiari, na `auto_scale_input` hubadilisha video kuwa fremu 81 kwa 16fps. Hurejesha uzito wa LoRA na faili ya usanidi.

- Category: Training
- Output: file
- Price: $0.005 / step (cheapest run $2.00 (2000 API credits))
- Run: `POST https://api.doitong.ru/v1/run/wan-trainer/t2v`
- Quote: `POST https://api.doitong.ru/v1/quote/wan-trainer/t2v`
- Docs page: https://doitong.com/sw/developers/models/wan-trainer/t2v

## 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.ru/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 ya kumbukumbu ya ZIP ya mafunzo kwa picha zenye mtindo thabiti, ikiweza kujumuisha faili za maandishi ya manukuu zilizopewa majina yanayolingana na faili zao za picha au video. Lenga kujumuisha angalau picha 10, video, au mchanganyiko wa zote mbili, huku mikusanyiko mikubwa ikipendelewa. |
| `number_of_steps` |  | integer | no | `400` | 100 – 20,000 | Jumla ya idadi ya hatua za mafunzo. |
| `learning_rate` |  | number | no | `0.0002` | 0.000001 – 1 | Mpangilio wa learning rate: mafunzo yanaweza kuwa ya haraka zaidi lakini yana hatari ya overfitting kiwango kinapoongezwa. |
| `trigger_phrase` |  | string | no | `` |  | Kauli inayochochea modeli kutoa picha. |
| `auto_scale_input` |  | boolean | no | `false` |  | Iwapo video ya ingizo irekebishwe kiotomatiki: true huweka urefu wake kuwa fremu 81 na kasi yake ya fremu kuwa 16 fps. |

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

### JavaScript

```javascript
const API = "https://api.doitong.ru/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.ru/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.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": "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.
