# Tripo H3.1 Multiview to 3D API

> 根据同一物体的 2 到 4 个视图构建 3D 模型，顺序为正面、左侧、背面、右侧

接收 `image_urls` 中同一物体的 2 到 4 张图像，顺序为正面、左侧、背面、右侧，其中必须提供正面视图。支持与单图像版本相同的选项：`face_limit`（1,000 到 2,000,000）、`pbr`、纹理和几何质量、`quad` 网格以及 `auto_size`。返回模型、预览渲染图和任务 ID。

- Model id: `tripo3d/h3.1/multiview-to-3d`
- Made by: Tripo
- Category: Image to 3D
- Output: 3d
- Price per run: from $0.20 / run (cheapest run $0.20 (200 API credits))
- Run: `POST https://api.doitong.ru/v1/run/tripo3d/h3.1/multiview-to-3d`
- Quote: `POST https://api.doitong.ru/v1/quote/tripo3d/h3.1/multiview-to-3d`
- Docs page: https://doitong.com/zh/developers/models/tripo3d/h3.1/multiview-to-3d

## Pricing

Price: **from $0.20 / run** (the lowest tier; the quote prices your exact input). Price per run: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $0.30 = 300 API credits (1 run × $0.30).

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/tripo3d/h3.1/multiview-to-3d` 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_urls` | `images` | array of image URL | yes |  | 2 – 4 items | 同一对象的多角度图像 URL，其中必须包含正面视图。按 [front, left, back, right] 顺序提供 2 到 4 个 URL。 |
| `face_limit` |  | integer \| null | no |  | 1,000 – 2,000,000 | 网格生成的明确面数目标；提供此值时会覆盖模型的自适应面数选择。 |
| `texture` |  | boolean | no | `true` |  | 控制模型是否接收生成的纹理。 |
| `pbr` |  | boolean | no | `true` |  | 启用 PBR 材质（基于物理的渲染）；设为 true 时也会启用纹理生成。 |
| `model_seed` |  | integer \| null | no |  |  | 用于使几何体生成可复现的种子。 |
| `texture_seed` |  | integer \| null | no |  |  | 用于使纹理生成可复现的种子。 |
| `texture_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | 纹理的质量设置。 |
| `geometry_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | 几何体的质量设置。 |
| `texture_alignment` |  | enum (string) | no | `original_image` | `original_image`, `geometry` | 纹理的对齐方式。 |
| `auto_size` |  | boolean | no | `false` |  | 自动缩放，使模型获得以米为单位测量的真实世界尺寸。 |
| `orientation` |  | enum (string) | no | `default` | `default`, `align_image` | 模型方向。 |
| `quad` |  | boolean | no | `false` |  | 启用四边形拓扑，在三角形面和 4 边四边形之间选择。对于四边形结果，只要 Tripo 以 FBX 字节提供数据，就会返回 FBX 文件。 |
| `enable_safety_checker` |  | boolean | no | `true` |  | 调用方获得授权后，可将其设置为 false 以放宽审核。 |

File parameters (`images`) 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
{
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ]
}
```

A fuller example:

```json
{
  "image_urls": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "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.ru/v1/run/tripo3d/h3.1/multiview-to-3d?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_urls": [
      "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
      "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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

    ]
  }),
});
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();

### Python

```python
import os
import requests

API = "https://api.doitong.ru/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "image_urls": [
        "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "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/h3.1/multiview-to-3d", 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": "tripo3d/h3.1/multiview-to-3d",
      "input": {
        "image_urls": [
          "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
          "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.
