# Hunyuan 3D Part Splitter API

> Membahagikan model 3D FBX kepada fail bahagian berasingan

Menerima fail FBX melalui `input_file_url` dan membahagikan model kepada beberapa bahagian, yang dikembalikan sebagai senarai fail FBX. Hanya FBX disokong, dengan saiz maksimum 100MB dan jumlah muka 30,000 atau kurang. Berfungsi paling baik pada model yang dijana AI.

- Model id: `hunyuan-3d/v3.1/part`
- Made by: Tencent
- Category: 3D
- Output: json
- Estimated price per run: $0.45 / run (cheapest run $0.45 (450 API credits))
- Run: `POST https://api.doitong.ru/v1/run/hunyuan-3d/v3.1/part`
- Quote: `POST https://api.doitong.ru/v1/quote/hunyuan-3d/v3.1/part`
- Docs page: https://doitong.com/ms/developers/models/hunyuan-3d/v3.1/part

## Pricing

Price: **$0.45 / run**. Estimated from the typical cost of one run. The quote is exactly what the run charges.

The full example input below costs $0.45 = 450 API credits (1 request × 450 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/hunyuan-3d/v3.1/part` 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 |
|---|---|---|---|---|---|---|
| `input_file_url` |  | string (file URL) | yes |  |  | Bekalkan model untuk pemisahan bahagian melalui URL fail FBX; format lain tidak disokong. Model yang dijana AIGC disyorkan, dan fail mestilah mematuhi kedua-dua had: 100 MB dan 30,000 muka. |

File parameters (`input_file_url`) 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
{
  "input_file_url": "https://example.com/your-file.bin"
}
```

A fuller example:

```json
{
  "input_file_url": "https://example.com/your-file.bin"
}
```

## 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/hunyuan-3d/v3.1/part?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "input_file_url": "https://example.com/your-file.bin"
  }'

# 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/hunyuan-3d/v3.1/part?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "input_file_url": "https://example.com/your-file.bin"
  }),
});
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 = {
    "input_file_url": "https://example.com/your-file.bin",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/hunyuan-3d/v3.1/part", 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": "hunyuan-3d/v3.1/part",
      "input": {
        "input_file_url": "https://example.com/your-file.bin"
      },
      "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.
