# Hi3D 3D Part Splitter API

> Hugawanya muundo wa 3D kuwa sehemu tofauti, ikiwa na violezo vya humanoid na viungio au kiwango cha jumla cha mgawanyo

Hugawanya modeli (GLB, STL au OBJ, hadi 200MB) kuwa sehemu. Katika hali ya mhusika, templeti a hadi f hutoa sehemu 6 hadi 2, na unaweza kuongeza viungio vya mpira au dovetail. Katika hali ya jumla, `level` huweka kiwango cha maelezo kuwa cha chini, cha kati au cha juu. Ugawanyaji wa wahusika kwa sasa huhamisha 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.com/v1/run/hitem3d/hi3d/split`
- Quote: `POST https://api.doitong.com/v1/quote/hitem3d/hi3d/split`
- Docs page: https://doitong.com/sw/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.com/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 |  |  | Toa modeli ya kugawanya kupitia URL inayoelekeza kwenye faili la GLB, STL au OBJ lisilozidi 200 MB. |
| `model` |  | enum (string) | no | `character` | `character`, `general` | Mbinu ya kugawanya modeli: ugawaji unaotegemea kiwango cha undani wa modeli yoyote hutumia 'general', huku ugawaji wa humanoid unaotegemea kiolezo ukitumia 'character' na kuruhusu viungio vya hiari. |
| `part` |  | enum (string) | no | `a` | `a`, `b`, `c`, `d`, `e`, `f` | Kiolezo cha kugawanya wakati modeli ni 'character': 'a' huzalisha sehemu 6; 'b', 5; 'c', 4 bila kichwa; 'd', 4 pamoja na kichwa; 'e', 3; na 'f', 2. |
| `joint` |  | enum (string) | no | `ball` | `none`, `ball`, `dovetail` | Aina ya kiungio kinachoingizwa kati ya sehemu wakati modeli ni 'character'. |
| `level` |  | enum (string) | no | `medium` | `low`, `medium`, `high` | Kiwango cha undani cha kugawanya wakati modeli ni 'general'. |
| `export_format` |  | enum (string) | no | `glb` | `glb`, `obj`, `stl`, `fbx`, `usdz` | Uteuzi wa umbizo la tokeo la modeli iliyozalishwa, unaozuiwa kuwa 'glb' unapotumia ugawaji wa character kwa sasa. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Huwezesha ukaguzi wa usalama wa maingizo kabla ya uchakataji wakati 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.com/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.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/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.com/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.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": "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.
