# Hi3D Texture API

> Tạo kết cấu cho lưới GLB chưa có kết cấu bằng hình ảnh tham chiếu

Áp dụng kết cấu cho hình học GLB hiện có chỉ gồm hình học, theo hình ảnh tham chiếu (PNG, JPEG hoặc WebP, tối đa 20MB). Chỉ hỗ trợ các mô hình v1.5: hitem3dv1.5 cung cấp độ phân giải từ 512 đến 1536pro, còn biến thể chân dung dùng 1536. Định dạng xuất là glb, obj, stl, fbx và usdz.

- Model id: `hitem3d/hi3d/texture`
- Made by: Hitem3D
- Category: 3D
- Output: 3d
- Estimated price per run: $0.30 / run (cheapest run $0.30 (300 API credits))
- Run: `POST https://api.doitong.com/v1/run/hitem3d/hi3d/texture`
- Quote: `POST https://api.doitong.com/v1/quote/hitem3d/hi3d/texture`
- Docs page: https://doitong.com/vi/developers/models/hitem3d/hi3d/texture

## Pricing

Price: **$0.30 / run**. Estimated from the typical cost of one run. The quote is exactly what the run charges.

The full example input below costs $0.30 = 300 API credits (1 request × 300 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/texture` 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

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `image_url` | `image` | string (image URL) | yes |  |  | Cung cấp tham chiếu kết cấu qua URL, dùng hình ảnh PNG, JPEG hoặc WebP với kích thước tệp tối đa 20 MB. |
| `mesh_url` |  | string | yes |  |  | Cung cấp hình học cần tạo kết cấu qua URL ở định dạng GLB; không hỗ trợ định dạng khác. Một nguồn phù hợp là đầu ra hình học image-to-3d được tạo với enable_texture=false. |
| `model` |  | enum (string) | no | `hitem3dv1.5` | `hitem3dv1.5`, `scene-portraitv1.5` | Phiên bản mô hình dùng để tạo kết cấu. Tác vụ kết cấu theo giai đoạn yêu cầu mô hình v1.5. |
| `resolution` |  | enum (string) \| null | no |  | `512`, `1024`, `1536`, `1536pro` | Chọn độ phân giải kết cấu hoặc để trống để dùng đề xuất của mô hình. Với scene-portraitv1.5, lựa chọn duy nhất là 1536, còn hitem3dv1.5 hỗ trợ 512, 1024, 1536 và 1536pro. |
| `export_format` |  | enum (string) | no | `glb` | `glb`, `obj`, `stl`, `fbx`, `usdz` | Định dạng dùng để lưu mô hình được tạo. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Nút kiểm tra an toàn cho hình ảnh đầu vào: true yêu cầu kiểm tra an toàn trước khi bắt đầu xử lý hình ảnh. |

File parameters (`image`) 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
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "mesh_url": "https://example.com/your-file.glb"
}
```

A fuller example:

```json
{
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "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/texture?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "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/texture?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "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 = {
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "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/texture", 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/texture",
      "input": {
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "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.
