# Hi3D 3D Part Splitter API

> تقسيم نموذج ثلاثي الأبعاد إلى أجزاء منفصلة، مع قوالب بشرية ومفاصل أو مستوى تفصيل عام

يقسم نموذجًا (GLB أو STL أو OBJ، حتى 200MB) إلى أجزاء. في وضع الشخصيات، توفر القوالب a إلى f من 6 أجزاء إلى جزأين، ويمكنك إضافة مفاصل ball أو dovetail بينها. في الوضع العام، يحدد `level` مستوى التحبب: منخفض أو متوسط أو مرتفع. تصدّر قسمة الشخصيات حاليًا بصيغة glb فقط.

- 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/ar/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 |  |  | قدّم النموذج للتقسيم عبر عنوان URL يشير إلى ملف GLB أو STL أو OBJ لا يتجاوز 200 MB. |
| `model` |  | enum (string) | no | `character` | `character`, `general` | طريقة تقسيم النموذج: يستخدم تقسيم أي نموذج القائم على درجة التفصيل 'general'، بينما يستخدم تقسيم الشخصيات البشرية القائم على القالب 'character' ويسمح بمفاصل اختيارية. |
| `part` |  | enum (string) | no | `a` | `a`, `b`, `c`, `d`, `e`, `f` | قالب التقسيم عندما يكون النموذج 'character': ينتج 'a' ستة أجزاء؛ و'b' خمسة؛ و'c' أربعة دون الرأس؛ و'd' أربعة مع الرأس؛ و'e' ثلاثة؛ و'f' جزأين. |
| `joint` |  | enum (string) | no | `ball` | `none`, `ball`, `dovetail` | نوع المفصل المُدرج بين الأجزاء عندما يكون النموذج 'character'. |
| `level` |  | enum (string) | no | `medium` | `low`, `medium`, `high` | درجة التفصيل للتقسيم عندما يكون النموذج 'general'. |
| `export_format` |  | enum (string) | no | `glb` | `glb`, `obj`, `stl`, `fbx`, `usdz` | اختيار تنسيق المخرج للنموذج المُولَّد، ومقيّد حاليًا بـ 'glb' عند استخدام تقسيم الشخصيات. |
| `enable_safety_checker` |  | boolean | no | `true` |  | يُمكّن فحوص السلامة للمدخلات قبل المعالجة عند كون القيمة 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.
