# Hi3D 3D Part Splitter API

> Tách mô hình 3D thành các phần riêng biệt, với template humanoid và khớp nối hoặc độ chi tiết tổng quát

Chia một mô hình (GLB, STL hoặc OBJ, tối đa 200MB) thành các phần. Ở chế độ nhân vật, các mẫu a đến f tạo từ 6 xuống 2 phần, và bạn có thể thêm khớp bi hoặc khớp đuôi én giữa chúng. Ở chế độ chung, `level` thiết lập độ chi tiết thấp, trung bình hoặc cao. Tính năng chia nhân vật hiện chỉ xuất glb.

- Model id: `hitem3d/hi3d/split`
- Made by: Hitem3D
- Category: 3D
- Output: 3d
- Estimated price per run: $0.40 / run (cheapest run $0.40 (400 API credits))
- Run: `POST https://api.doitong.ru/v1/run/hitem3d/hi3d/split`
- Quote: `POST https://api.doitong.ru/v1/quote/hitem3d/hi3d/split`
- Docs page: https://doitong.com/vi/developers/models/hitem3d/hi3d/split

## Pricing

Price: **$0.40 / run**. Estimated from the typical cost of one run. The quote is exactly what the run charges.

The full example input below costs $0.40 = 400 API credits (1 request × 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.ru/v1/quote/hitem3d/hi3d/split` 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 |
|---|---|---|---|---|---|---|
| `mesh_url` |  | string | yes |  |  | Cung cấp mô hình để tách qua URL trỏ đến tệp GLB, STL hoặc OBJ tối đa 200 MB. |
| `model` |  | enum (string) | no | `character` | `character`, `general` | Phương pháp tách mô hình: tách theo độ chi tiết cho mọi mô hình dùng 'general', còn tách hình người theo mẫu dùng 'character' và cho phép khớp nối tùy chọn. |
| `part` |  | enum (string) | no | `a` | `a`, `b`, `c`, `d`, `e`, `f` | Mẫu tách khi mô hình là 'character': 'a' tạo 6 phần; 'b', 5 phần; 'c', 4 phần không có đầu; 'd', 4 phần có đầu; 'e', 3 phần; và 'f', 2 phần. |
| `joint` |  | enum (string) | no | `ball` | `none`, `ball`, `dovetail` | Loại khớp nối được chèn giữa các phần khi mô hình là 'character'. |
| `level` |  | enum (string) | no | `medium` | `low`, `medium`, `high` | Độ chi tiết khi tách mô hình là 'general'. |
| `export_format` |  | enum (string) | no | `glb` | `glb`, `obj`, `stl`, `fbx`, `usdz` | Lựa chọn định dạng đầu ra cho mô hình được tạo, hiện chỉ giới hạn ở 'glb' khi dùng tách nhân vật. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Bật kiểm tra an toàn đầu vào trước khi xử lý khi là true. |

## Example input

Required parameters only:

```json
{
  "mesh_url": "https://example.com/your-file.glb"
}
```

A fuller example:

```json
{
  "mesh_url": "https://example.com/your-file.glb"
}
```

## 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.ru/v1/run/hitem3d/hi3d/split?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "mesh_url": "https://example.com/your-file.glb"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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/hitem3d/hi3d/split?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "mesh_url": "https://example.com/your-file.glb"
  }),
});
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.ru/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "mesh_url": "https://example.com/your-file.glb",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/hitem3d/hi3d/split", 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.ru/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": "hitem3d/hi3d/split",
      "input": {
        "mesh_url": "https://example.com/your-file.glb"
      },
      "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.
