# High Quality Stable Video Diffusion API

> Κινεί μία στατική εικόνα για τη δημιουργία σύντομου αποσπάσματος με ρυθμιζόμενο επίπεδο κίνησης, θόρυβο και ρυθμό καρέ

Μοντέλο από εικόνα σε βίντεο, βασισμένο στο SVD v1.1, που ξεκινά από μία εικόνα ως `image_url`. Χρησιμοποιήστε `motion_bucket_id` (1 έως 255) για να ελέγξετε την κίνηση, `cond_aug` (0 έως 10) για προσθήκη θορύβου ώστε το αποτέλεσμα να απομακρύνεται περισσότερο από την πηγή και `fps` (10 έως 100) για τον ρυθμό αναπαραγωγής. Δεν υπάρχει κειμενικό prompt και ένα `seed` κάνει τα αποτελέσματα επαναλήψιμα.

- Model id: `stable-video`
- Made by: Stability AI
- Category: Image to Video
- Output: video
- Price: $0.075 / video (cheapest run $0.075 (75 API credits))
- Run: `POST https://api.doitong.com/v1/run/stable-video`
- Quote: `POST https://api.doitong.com/v1/quote/stable-video`
- Docs page: https://doitong.com/el/developers/models/stable-video

## Pricing

Price: **$0.075 / video**. Billed once per generated video.

The full example input below costs $0.075 = 75 API credits (1 video × 75 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/stable-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 |
|---|---|---|---|---|---|---|
| `image_url` | `image` | string (image URL) | yes |  | ≥ 1 characters | Εικόνα έναρξης για την παραγωγή, παρεχόμενη μέσω URL. |
| `seed` |  | integer \| null | no |  |  | Seed για αναπαραγωγή εικόνων στο Stable Diffusion. Μια εικόνα μπορεί να αναπαραχθεί ακριβώς σε κάθε εκτέλεση, αν παραμείνουν αμετάβλητα η έκδοση του μοντέλου, το prompt και το seed. |
| `motion_bucket_id` |  | integer | no | `127` | 1 – 255 | ID κάδου κίνησης, όπου οι αυξανόμενες τιμές αντιστοιχούν σε ολοένα ισχυρότερη κίνηση στο παραγόμενο βίντεο. |
| `cond_aug` |  | number | no | `0.02` | 0 – 10 | Επίπεδο θορύβου που εφαρμόζεται στο καρέ καθοδήγησης· η αύξησή του ενθαρρύνει περισσότερη κίνηση εις βάρος της ομοιότητας με την αρχική εικόνα. |
| `fps` |  | integer | no | `25` | 10 – 100 | Ρυθμός καρέ βίντεο εξόδου, μετρημένος σε καρέ ανά δευτερόλεπτο. |

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
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "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/stable-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "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/stable-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "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 = {
    "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/stable-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": "stable-video",
      "input": {
        "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.
