# Marey Realism V1.5 · I2V API

> Marey تصویر سے ویڈیو، آپ کی تصویر کو پہلے فریم کے طور پر استعمال کرتے ہوئے، 5s یا 10s اور پانچ ابعاد کے ساتھ

پرامپٹ استعمال کرتے ہوئے ساکن تصویر کو کلپ میں اینیمیشن کرتا ہے۔ `image_url` پہلا فریم ہے۔ `duration` 5s یا 10s ہے، اور `dimensions` 1920x1080، 1080x1920، 1152x1152، 1536x1152 اور 1152x1536 فراہم کرتا ہے۔ یہ `negative_prompt`، `guidance_scale` اور `seed` (-1 بے ترتیب کے لیے) بھی قبول کرتا ہے۔

- Made by: Moonvalley
- Category: Image to Video
- Output: video
- Price: $0.30 / second (5 s ≈ $1.50) (cheapest run $1.50 (1500 API credits))
- Run: `POST https://api.doitong.com/v1/run/moonvalley/marey/i2v`

## Pricing

Price: **$0.30 / second (5 s ≈ $1.50)**. Billed per second of output (`duration`, default 10). Billed in started blocks of 5 seconds.

The full example input below costs $1.50 = 1500 API credits (5 s × 300 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/moonvalley/marey/i2v` 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 |  |  | ویڈیو تخلیق کی رہنمائی کرنے والا پرامپٹ۔ |
| `dimensions` |  | enum (string) | no | `1920x1080` | `1920x1080`, `1080x1920`, `1152x1152`, `1536x1152`, `1152x1536` | آؤٹ پٹ ویڈیو کے dimensions، width x height کی صورت میں۔ |
| `duration` |  | enum (string) | no | `5s` | `5s`, `10s` | آؤٹ پٹ ویڈیو کی لمبائی۔ |
| `negative_prompt` |  | string \| null | no | `<synthetic> <scene cut> low-poly, flat shader, bad rigging, stiff animation, uncanny eyes, low-quality textures, looping glitch, cheap effect, overbloom, bloom spam, default lighting, game asset, stiff face, ugly specular, AI artifacts` |  | ماڈل سے بچنے کے لیے ناپسندیدہ خصوصیات بیان کرنے والا پرامپٹ۔ |
| `seed` |  | integer \| null | no | `-1` |  | random-number seed؛ ہر run کے لیے نئی بے ترتیب قدر کی درخواست کرنے کے لیے -1۔ |
| `guidance_scale` |  | number \| null | no |  |  | اس guidance setting کو بڑھا کر پرامپٹ adherence میں اضافہ کیا جا سکتا ہے۔ اس کی اجازت شدہ حد 0–20 ہے۔ |
| `image_url` | `image` | string (image URL) | yes |  |  | ویڈیو کے ابتدائی فریم کی تصویر فراہم کرنے والا URL۔ |

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": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

## 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/moonvalley/marey/i2v?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",
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# 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/moonvalley/marey/i2v?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",
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }),
});
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",
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/moonvalley/marey/i2v", 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": "moonvalley/marey/i2v",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
