# Sam 3 · Video RLE API

> Segmentasi video dengan seed URL mask, kontrol indeks bingkai, dan batas bawah detection threshold yang lebih rendah

Mensegmentasikan video dengan SAM 3 menggunakan `prompt` teks, prompt titik atau kotak, atau mask awal dari `mask_url` yang diterapkan pada `frame_index`. `detection_threshold` berkisar dari 0.01 hingga 1, dan nilai yang lebih rendah seperti 0.2 hingga 0.3 dapat membantu saat prompt teks gagal. Dapat mengembalikan zip kotak pembatas per bingkai dengan `boundingbox_zip`.

- Model id: `sam-3/video-rle`
- Made by: Meta
- Category: Video to Video
- Output: video
- Price per 16 frames of your input video: $0.005 / 16 frames of input video (cheapest run $0.005 (5 API credits))
- Run: `POST https://api.doitong.com/v1/run/sam-3/video-rle`
- Quote: `POST https://api.doitong.com/v1/quote/sam-3/video-rle`
- Docs page: https://doitong.com/id/developers/models/sam-3/video-rle

## Pricing

Price: **$0.005 / 16 frames of input video**. Price per 16 frames of your input video: 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.

The full example input below costs $0.095 = 95 API credits (19 × 16 frames input video × $0.005).

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/sam-3/video-rle` 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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | URL video untuk segmentasi. |
| `mask_url` | `mask` | string (image URL) \| null | no |  |  | URL mask untuk penerapan awal. |
| `prompt` |  | string | no | `` |  | Prompt segmentasi yang mendukung beberapa objek yang dilacak melalui deskripsi yang dipisahkan koma, seperti 'person, cloth'. |
| `point_prompts` |  | array of object {x, y, label, object_id, frame_index} | no | `[]` |  | Daftar prompt titik yang menentukan indeks bingkai. |
| `point_prompts[].x` |  | integer \| null | no |  |  | Posisi prompt pada sumbu X. |
| `point_prompts[].y` |  | integer \| null | no |  |  | Posisi prompt pada sumbu Y. |
| `point_prompts[].label` |  | enum (integer) \| null | no |  | `0`, `1` | Label foreground/background: 1 menunjukkan foreground; 0 menunjukkan background. |
| `point_prompts[].object_id` |  | integer \| null | no |  |  | Pengenal opsional yang mengelompokkan prompt untuk menyempurnakan satu objek. Jika teks juga diberikan sebagai prompt, pengenal ini menentukan objek terdeteksi mana yang disempurnakan oleh titik tersebut. |
| `point_prompts[].frame_index` |  | integer \| null | no |  |  | Indeks yang mengidentifikasi bingkai untuk interaksi. |
| `box_prompts` |  | array of object {x_min, y_min, x_max, y_max, object_id, frame_index} | no | `[]` |  | Daftar prompt kotak, dengan frame_index opsional untuk setiap entri. |
| `box_prompts[].x_min` |  | integer \| null | no |  |  | Koordinat x minimum untuk kotak. |
| `box_prompts[].y_min` |  | integer \| null | no |  |  | Koordinat y minimum untuk kotak. |
| `box_prompts[].x_max` |  | integer \| null | no |  |  | Koordinat X maksimum untuk kotak. |
| `box_prompts[].y_max` |  | integer \| null | no |  |  | Koordinat Y maksimum untuk kotak. |
| `box_prompts[].object_id` |  | integer \| null | no |  |  | Pengenal opsional yang mengelompokkan kotak untuk menyempurnakan satu objek. |
| `box_prompts[].frame_index` |  | integer \| null | no |  |  | Indeks yang mengidentifikasi bingkai untuk interaksi. |
| `apply_mask` |  | boolean | no | `false` |  | Apakah masking diterapkan pada video. |
| `boundingbox_zip` |  | boolean | no | `false` |  | Apakah akan mengembalikan arsip ZIP yang berisi overlay kotak pembatas untuk setiap bingkai. |
| `detection_threshold` |  | number | no | `0.5` | 0.01 – 1 | Batas skor keyakinan deteksi dengan bawaan 0.5 untuk objek yang ada dan 0.7 untuk objek baru. Dalam rentang 0.0–1.0, nilai yang lebih kecil menukar presisi dengan lebih banyak deteksi; coba 0.2–0.3 saat prompt teks gagal. |
| `frame_index` |  | integer | no | `0` |  | Indeks bingkai untuk interaksi awal saat menyediakan mask_url. |

File parameters (`video`, `mask`) 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
{
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

## 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/sam-3/video-rle?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }'

# 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/sam-3/video-rle?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }),
});
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 = {
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/sam-3/video-rle", 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": "sam-3/video-rle",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
      },
      "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.
