# Veo 3.1 Image to Video API

> Veo 3.1 میں تصویر کو مکالمے اور آواز کے ساتھ 4 سے 8 سیکنڈ کے کلپ میں اینیمیشن دیتا ہے، 4K تک

Veo 3.1 ایک جامد تصویر کو حقیقت پسندانہ فوٹیج میں بدلتا ہے جو تصویر کے موضوع اور فریمنگ کو برقرار رکھتی ہے، جبکہ آواز، صوتی اثرات اور موسیقی تصویر کے ساتھ تخلیق ہوتے ہیں۔ 720p، 1080p یا 4K پر 4، 6 یا 8 سیکنڈ؛ فریم تصویر کی پیروی کرتا ہے یا 16:9 یا 9:16 پر مجبور کیا جا سکتا ہے۔ کم قیمت کے لیے آڈیو بند کیا جا سکتا ہے۔

- Model id: `veo3.1/image-to-video`
- Made by: Google
- Category: Image to Video
- Output: video
- Price: from $0.20 / second (8 s ≈ $1.60) (cheapest run $1.60 (1600 API credits))
- Run: `POST https://api.doitong.com/v1/run/veo3.1/image-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/veo3.1/image-to-video`
- Docs page: https://doitong.com/ur/developers/models/veo3.1/image-to-video

## Pricing

Price: **from $0.20 / second (8 s ≈ $1.60)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 8).

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

- When `resolution` = 4k and `generate_audio` = true: $0.60 (600 API credits) / second
- When `resolution` = 4k: $0.40 (400 API credits) / second
- When `generate_audio` = true: $0.40 (400 API credits) / second

The full example input below costs $2.40 = 2400 API credits (6 s × 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.com/v1/quote/veo3.1/image-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 |  | ≤ 20000 characters | تخلیق کے لیے مطلوبہ ویڈیو کی متنی وضاحت۔ |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `16:9`, `9:16` | آؤٹ پٹ ویڈیو کا aspect ratio، صرف 16:9 یا 9:16 تک محدود۔ |
| `duration` |  | enum (string) | no | `8s` | `4s`, `6s`, `8s` | آؤٹ پٹ ویڈیو کی لمبائی۔ |
| `negative_prompt` |  | string \| null | no |  |  | ویڈیو تخلیق کی سمت متعین کرنے کے لیے استعمال ہونے والا negative پرامپٹ۔ |
| `resolution` |  | enum (string) | no | `720p` | `720p`, `1080p`, `4k` | آؤٹ پٹ ویڈیو کے لیے استعمال ہونے والا ریزولوشن۔ |
| `generate_audio` |  | boolean | no | `true` |  | کنٹرول کرتا ہے کہ ویڈیو میں تیار کردہ آڈیو شامل ہو یا نہیں۔ |
| `seed` |  | integer \| null | no |  |  | سیڈ کی قدر جو بے ترتیب اعداد کی تخلیق شروع کرتی ہے۔ |
| `auto_fix` |  | boolean | no | `false` |  | Content-policy checks یا دیگر validation کی ناکامیوں کو حل کرنے کی کوشش کے لیے پرامپٹس کی خودکار rewriting۔ |
| `safety_tolerance` |  | enum (string) | no | `4` | `1`, `2`, `3`, `4`, `5`, `6` | content-moderation tolerance کو کم ترین پابندی والی سطح 6 اور سخت ترین سطح 1 کے درمیان مقرر کریں؛ 1 زیادہ تر مواد کو روکتی ہے۔ |
| `image_url` | `image` | string (image URL) | yes |  |  | Animation source تصویر URL؛ 16:9 یا 9:16 سے مختلف proportions ہونے پر خودکار cropping کی جاتی ہے۔ تجویز کردہ source کم از کم 720p کا ہو اور پہلے ہی ان ratios میں سے ایک استعمال کرے۔ |

File parameters (`image`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "prompt": "The fox turns toward the camera and says \"Have you seen my friends?\" in a soft voice, fireflies drift by",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "prompt": "The fox turns toward the camera and says \"Have you seen my friends?\" in a soft voice, fireflies drift by",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "duration": 6,
  "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.com/v1/run/veo3.1/image-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "The fox turns toward the camera and says \"Have you seen my friends?\" in a soft voice, fireflies drift by",
    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "duration": 6,
    "resolution": "720p"
  }'

# 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/veo3.1/image-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "The fox turns toward the camera and says \"Have you seen my friends?\" in a soft voice, fireflies drift by",
    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "duration": 6,
    "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.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "The fox turns toward the camera and says \"Have you seen my friends?\" in a soft voice, fireflies drift by",
    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "duration": 6,
    "resolution": "720p",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/veo3.1/image-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": "veo3.1/image-to-video",
      "input": {
        "prompt": "The fox turns toward the camera and says \"Have you seen my friends?\" in a soft voice, fireflies drift by",
        "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "duration": 6,
        "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.
