# PixVerse V4 Text To Video API

> تبدیل متن به ویدیوی PixVerse V4 با نسبت تصویر قابل انتخاب، وضوح تا 1080p و پیش‌تنظیم‌های سبک

از `prompt` با حداکثر 2048 بایت UTF-8 ویدیو ایجاد می‌کند. `aspect_ratio` را از میان 16:9، 4:3، 1:1، 3:4 و 9:16 و `resolution` را از 360p تا 1080p انتخاب کنید. `duration` برابر 5 یا 8 ثانیه است و 1080p روی 5 می‌ماند. `style`، `negative_prompt` و `seed` پشتیبانی می‌شوند؛ این گونه متنی گزینه حرکت دوربین ندارد.

- Run: `POST https://api.doitong.com/v1/run/pixverse/v4/text-to-video`

## Pricing

Price: **from $0.15 / run** (the lowest tier; the quote prices your exact input). Price per run: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

Price by tier:

- 360p: $0.15 / run
- 540p: $0.15 / run
- 720p: $0.20 / run
- 360p, 8_s: $0.30 / run
- 540p, 8_s: $0.30 / run
- 720p, 8_s: $0.40 / run
- 1080p: $0.40 / run
- 1080p, 8_s: $0.80 / run

The full example input below costs $0.20 = 200 API credits (1 run × $0.20 (720p)).

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/pixverse/v4/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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | پرامپت تولید ویدیو با سقف اندازه بر اساس بایت: حتی متن کوتاه از نظر بصری ممکن است هنگام استفاده از ایموجی، حروف دارای اَکسان یا نویسه‌های غیرلاتین، به‌دلیل اشغال چند بایت برای هر نویسه، از این سقف فراتر برود. حداکثر طول کدگذاری‌شده 2048 بایت با UTF-8 است؛ تعداد نویسه‌ها تعیین نمی‌کند که متن در این محدوده جا می‌گیرد یا نه. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | نسبت ابعاد ویدیوی خروجی. |
| `resolution` |  | enum (string) | no | `720p` | `360p`, `540p`, `720p`, `1080p` | وضوح ویدیوی خروجی. |
| `duration` |  | enum (string) | no | `5` | `5`, `8` | مدت ویدیو، با حداکثر 5 ثانیه برای خروجی 1080p؛ طول را بر حسب ثانیه مشخص کنید. |
| `negative_prompt` |  | string | no | `` |  | پرامپت منفی تولید با محدودیت طول بر اساس بایت: حتی متن کوتاه از نظر بصری ممکن است به‌دلیل اشغال چند بایت توسط ایموجی، حروف دارای اَکسان و نویسه‌های غیرلاتین، از سقف فراتر برود. حداکثر 2048 بایت است که با UTF-8 اندازه‌گیری می‌شود، نه تعداد نویسه‌ها. |
| `style` |  | enum (string) \| null | no |  | `anime`, `3d_animation`, `clay`, `comic`, `cyberpunk` | سبک اعمال‌شده بر ویدیوی تولیدشده. |
| `seed` |  | integer \| null | no |  |  | seed برای تولید تکرارپذیر ویدیو. بازتولید دقیق در هر اجرا به ثابت‌ماندن نسخه مدل، پرامپت و seed نیاز دارد. |
| `enable_safety_checker` |  | boolean | no | `true` |  | با تنظیم false، در صورت مجاز بودن فراخواننده، می‌توان بررسی را آسان‌گیرانه‌تر کرد. |

## 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.com/v1/run/pixverse/v4/text-to-video?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.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/pixverse/v4/text-to-video?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.com/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/pixverse/v4/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.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": "pixverse/v4/text-to-video",
      "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.
