# Wan 3.0 Text to Video API

> Alibaba Wan 3.0 — 2 līdz 30 sekunžu klipi ar ģenerētu audio līdz 1080p izšķirtspējā.

Wan 3.0 no uzvednes izveido garus, saskaņotus kadrus no 2 līdz 30 sekundēm, pēc noklusējuma ar ģenerētu skaņu. Neobligāts spriešanas solis plāno sarežģītas ainas, bet uzvednes paplašināšana pēc noklusējuma ir ieslēgta. 480p, 720p vai 1080p sešās malu attiecībās vai ar adaptīvu kadrējumu.

## Pricing

Price: **from $0.05 / second (5 s ≈ $0.25)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 30).

The full example input below costs $0.50 = 500 API credits (5 s × 100 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/alibaba/wan-3.0/text-to-video` 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

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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | 1 – 20000 characters | Teksta norādes ģenerējamā video aprakstam. |
| `resolution` |  | enum (string) | no | `1080p` | `480p`, `720p`, `1080p` | Iegūtā video izšķirtspējas līmenis. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Izvades malu attiecība ar adaptīvas izvēles iespēju. |
| `duration` |  | integer \| null | no | `5` | 2 – 30 | Izvades garums: null iespējo viedo ilgumu, kas balstīts uz uzvedni un atsauces multividi; pretējā gadījumā norādītā vērtība nosaka sekundes. |
| `audio` | `generate_audio` | boolean | no | `true` |  | Nosaka, vai tiek iekļauts ģenerētais audio. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Nosaka, vai uzvedne pirms ģenerēšanas tiek gudri pārrakstīta. Atspējojot pārrakstīšanu, paredzama kvalitātes samazināšanās, taču aizkave samazinās aptuveni par 20–60 sekundēm. |
| `enable_thinking` |  | boolean | no | `false` |  | Iespējo papildu spriešanu pirms ģenerēšanas sākuma. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 |  |

## Example input

Required parameters only:

```json
{
  "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera"
}
```

A fuller example:

```json
{
  "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
  "duration": 5,
  "resolution": "720p"
}
```

## 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/alibaba/wan-3.0/text-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
    "duration": 5,
    "resolution": "720p"
  }'

# 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/alibaba/wan-3.0/text-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
    "duration": 5,
    "resolution": "720p"
  }),
});
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 panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
    "duration": 5,
    "resolution": "720p",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/alibaba/wan-3.0/text-to-video", 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": "alibaba/wan-3.0/text-to-video",
      "input": {
        "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
        "duration": 5,
        "resolution": "720p"
      },
      "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.
