# Wan-2.1 Text-to-Video API

> Wan 2.1 szöveg-videó 480p–720p kimenettel, álló- vagy fekvő tájolással és opcionális turbo móddal

Rövid videoklipet generál szöveges `prompt` alapján. A felbontás 480p, 580p vagy 720p, a képarány 16:9 vagy 9:16. A `num_frames` 81–100, a `frames_per_second` 5–24. Elfogad `negative_prompt` és `seed` értéket, opcionális promptbővítést, valamint a gyorsabb futtatást biztosító `turbo_mode` kapcsolót.

- Model id: `wan-t2v`
- Made by: Alibaba
- Category: Text to Video
- Output: video
- Price: from $0.20 / video (cheapest run $0.20 (200 API credits))
- Run: `POST https://api.doitong.ru/v1/run/wan-t2v`
- Quote: `POST https://api.doitong.ru/v1/quote/wan-t2v`
- Docs page: https://doitong.com/hu/developers/models/wan-t2v

## Pricing

Price: **from $0.20 / video** (the lowest tier; the quote prices your exact input). Billed once per generated video.

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `num_frames` > 81 and `resolution` is 580p, 720p: $0.50 (500 API credits) / video
- When `resolution` is 580p, 720p: $0.40 (400 API credits) / video
- When `num_frames` > 81: $0.25 (250 API credits) / video

The full example input below costs $0.40 = 400 API credits (1 video × 400 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-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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Videógenerálást vezérlő szöveges utasítások. |
| `negative_prompt` |  | string | no | `bright colors, overexposed, static, blurred details, subtitles, style, artwork, painting, picture, still, overall gray, worst quality, low quality, JPEG compression residue, ugly, incomplete, extra fingers, poorly drawn hands, poorly drawn faces, deformed, disfigured, malformed limbs, fused fingers, still picture, cluttered background, three legs, many people in the background, walking backwards` |  | Videógeneráláskor alkalmazott negatív prompt. |
| `num_frames` |  | integer \| null | no | `81` | 81 – 100 | A generáláshoz használt képkockák száma, 81 és 100 között, a szélsőértékeket is beleértve. |
| `frames_per_second` |  | integer \| null | no | `16` | 5 – 24 | A generált videó képkockasebessége képkocka/másodpercben, 5 és 24 között. |
| `seed` |  | integer \| null | no |  |  | A generálást reprodukálhatóvá tevő seed. A None érték véletlenszerű seedet választ. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `580p`, `720p` | A kimeneti videó felbontása: 480p, 580p vagy 720p. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `9:16`, `16:9` | A kimeneti videó képaránya: 16:9 vagy 9:16. |
| `num_inference_steps` |  | integer | no | `30` | 2 – 40 | Mintavételezési lépések száma; a szám növelése hosszabb feldolgozási időért cserébe jobb minőséget biztosít. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Biztonsági ellenőrzési kapcsoló, amelynek kikapcsolt állapotához fiókengedélyezés szükséges. Engedélyezés nélkül minden kérés ellenőrzésen esik át a beállítástól függetlenül; a true aktiválja az ellenőrzőt. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | A promptbővítés engedélyezését vezérli. |
| `turbo_mode` |  | boolean | no | `false` |  | Gyorsabb videógenerálási kapcsoló. Engedélyezése észrevehető vizuális minőségromlás nélkül csökkenti a generálási időt. |

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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-t2v?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"
  }'

# 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-t2v?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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 = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/wan-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-t2v",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
