# Triposplat API

> Chuyển một ảnh thành tệp Gaussian splat 3D, xuất dưới dạng .ply hoặc .splat

Tạo Gaussian splat 3D từ một hình ảnh duy nhất (`image_url`) thay vì lưới. `num_gaussians` nằm trong khoảng từ 32,768 đến 262,144, còn `output_format` là ply hoặc splat. Bạn cũng có thể đặt `num_inference_steps` (1-50), `guidance_scale` và `seed`. Phản hồi bao gồm số Gaussian thực tế và hình ảnh đã xóa nền mà mô hình đã sử dụng.

- Model id: `tripo3d/triposplat`
- Made by: Tripo
- Category: Image to 3D
- Output: 3d
- Price: $0.05 / request (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.com/v1/run/tripo3d/triposplat`
- Quote: `POST https://api.doitong.com/v1/quote/tripo3d/triposplat`
- Docs page: https://doitong.com/vi/developers/models/tripo3d/triposplat

## Pricing

Price: **$0.05 / request**. Billed once per request.

The full example input below costs $0.05 = 50 API credits (1 request × 50 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/tripo3d/triposplat` 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 |  |  | URL hình ảnh nguồn để chuyển đổi thành Gaussian splat 3D. |
| `num_gaussians` |  | integer | no | `262144` | 32,768 – 262,144 | Số lượng Gaussian mong muốn cho splat được tạo sinh, được làm tròn nội bộ đến bội số gần nhất của 32. Tăng giá trị này sẽ thêm chi tiết nhưng cũng làm tăng kích thước tệp và làm chậm quá trình kết xuất. |
| `num_inference_steps` |  | integer | no | `20` | 1 – 50 | Số bước cho bộ lấy mẫu flow-matching. |
| `guidance_scale` |  | number | no | `3` | 0 – 10 | Kiểm soát hướng dẫn không cần bộ phân loại, trong đó các thiết lập mạnh hơn sẽ thêm chi tiết và đưa kết quả gần hơn với hình ảnh nguồn, nhưng có nguy cơ làm màu quá bão hòa. Hướng dẫn bị tắt ở mức 1.0 trở xuống. |
| `output_format` |  | enum (string) | no | `ply` | `ply`, `splat` | Định dạng tệp đầu ra cho Gaussian splat. |
| `seed` |  | integer \| null | no |  |  | Seed dùng để tái tạo kết quả. Đặt thành None sẽ chọn seed ngẫu nhiên. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Công tắc kiểm tra an toàn cho hình ảnh nguồn. |

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"
}
```

A fuller example:

```json
{
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

## 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/tripo3d/triposplat?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"
  }'

# 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/tripo3d/triposplat?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }),
});
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",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/tripo3d/triposplat", 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": "tripo3d/triposplat",
      "input": {
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
