# Hi3D 3D Part Splitter API

> Roinnidh e modail 3D na phàirtean fa leth, le teamplaidean humanoid agus altan no granularity choitcheann

Roinnidh modail (GLB, STL no OBJ, suas ri 200MB) na phàirtean. Ann am modh charactar, bheir na teamplaidean a gu f bho 6 sìos gu 2 phàirt, agus faodaidh tu co-cheanglaichean ball no dovetail a chur eatorra. Ann am modh coitcheann, suidhichidh `level` gràineileachd ìosal, mheadhanach no àrd. Chan eil roinneadh charactaran a’ às-phortadh ach glb an-dràsta.

- 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/gd/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.

## 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.
