# Hi3D 3D Part Splitter API

> 3D मॉडल को अलग-अलग भागों में विभाजित करता है, जिसमें ह्यूमनॉइड टेम्पलेट और जॉइंट या सामान्य ग्रैन्युलैरिटी शामिल हैं

मॉडल (GLB, STL या OBJ, अधिकतम 200MB) को भागों में विभाजित करता है। कैरेक्टर मोड में, a से f तक के टेम्पलेट 6 से 2 भागों तक देते हैं, और आप उनके बीच बॉल या डवटेल जॉइंट जोड़ सकते हैं। सामान्य मोड में, `level` निम्न, मध्यम या उच्च ग्रैन्युलैरिटी निर्धारित करता है। कैरेक्टर विभाजन वर्तमान में केवल glb एक्सपोर्ट करता है।

- 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`

## 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 |  |  | मॉडल को विभाजित करने के लिए अधिकतम 200 MB की GLB, STL या OBJ फ़ाइल की ओर संकेत करने वाला URL दें। |
| `model` |  | enum (string) | no | `character` | `character`, `general` | मॉडल को विभाजित करने की विधि: किसी भी मॉडल का ग्रैन्युलैरिटी-आधारित विभाजन 'general' का उपयोग करता है, जबकि टेम्पलेट-आधारित ह्यूमनॉइड विभाजन 'character' का उपयोग करता है और वैकल्पिक जॉइंट की अनुमति देता है। |
| `part` |  | enum (string) | no | `a` | `a`, `b`, `c`, `d`, `e`, `f` | जब मॉडल 'character' हो, तब विभाजन टेम्पलेट: 'a' से 6 भाग बनते हैं; 'b' से 5; 'c' से हेड के बिना 4; 'd' से हेड सहित 4; 'e' से 3; और 'f' से 2। |
| `joint` |  | enum (string) | no | `ball` | `none`, `ball`, `dovetail` | जब मॉडल 'character' हो, तब भागों के बीच डाले जाने वाले जॉइंट का प्रकार। |
| `level` |  | enum (string) | no | `medium` | `low`, `medium`, `high` | जब मॉडल 'general' हो, तब विभाजन के लिए ग्रैन्युलैरिटी। |
| `export_format` |  | enum (string) | no | `glb` | `glb`, `obj`, `stl`, `fbx`, `usdz` | जेनरेट किए गए मॉडल के लिए आउटपुट फ़ॉर्मैट चयन; वर्तमान में कैरेक्टर विभाजन का उपयोग करते समय 'glb' तक सीमित। |
| `enable_safety_checker` |  | boolean | no | `true` |  | true होने पर प्रोसेसिंग से पहले इनपुट पर सुरक्षा जाँच सक्षम करता है। |

## 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.
