# Tripo H3.1 Multiview to 3D API

> 1つのオブジェクトを正面、左、背面、右の順に2〜4視点から3Dモデル化

同じオブジェクトを撮影した2〜4枚の画像を `image_urls` に指定し、正面、左、背面、右の順に並べます。正面画像は必須です。単一画像版と同じ `face_limit`（1,000〜2,000,000）、`pbr`、テクスチャとジオメトリの品質、`quad` メッシュ、`auto_size` に対応します。モデル、プレビュー画像、タスクIDを返します。

- 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/ja/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 | 1つのオブジェクトの複数角度の画像URL。正面画像は必須です。[front, left, back, right]の順に2～4個のURLを指定します。 |
| `face_limit` |  | integer \| null | no |  | 1,000 – 2,000,000 | メッシュ生成時の明示的な面数目標。指定するとモデルの適応的な面数選択を上書きします。 |
| `texture` |  | boolean | no | `true` |  | モデルに生成テクスチャを渡すかどうかを制御します。 |
| `pbr` |  | boolean | no | `true` |  | PBRマテリアル（Physically Based Rendering）を有効にします。trueの場合はテクスチャ生成も有効になります。 |
| `model_seed` |  | integer \| null | no |  |  | ジオメトリ生成を再現可能にするためのシード。 |
| `texture_seed` |  | integer \| null | no |  |  | テクスチャ生成を再現可能にするためのシード。 |
| `texture_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | テクスチャの品質設定。 |
| `geometry_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | ジオメトリの品質設定。 |
| `texture_alignment` |  | enum (string) | no | `original_image` | `original_image`, `geometry` | テクスチャの位置合わせ方法。 |
| `auto_size` |  | boolean | no | `false` |  | モデルの寸法をメートル単位の実寸に合わせる自動スケーリング。 |
| `orientation` |  | enum (string) | no | `default` | `default`, `align_image` | モデルの向き。 |
| `quad` |  | boolean | no | `false` |  | 三角形面と4辺の四角形面を、quad topologyを有効にして切り替えます。四角形の結果では、TripoがデータをFBXバイトとして提供した場合にFBXファイルが返されます。 |
| `enable_safety_checker` |  | boolean | no | `true` |  | 呼び出し元に権限がある場合、false に設定するとスクリーニングを緩和できます。 |

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

```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/tripo3d/h3.1/multiview-to-3d?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({

    ]
  }),
});
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 = {
    "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.

### Output fields (`output`)

| Field | Type | Description |
|---|---|---|
| `model_mesh` | object {url, content_type, file_name, file_size} | 生成された3Dモデルを含むGLBまたはFBXファイル。形式はTripoの出力により決まります。 |
| `model_urls` | object {glb, fbx, base_model, pbr_model} | 3Dモデルの代替バージョンを指すURL。 |
| `rendered_image` | object {url, content_type, file_name, file_size} \| null | 生成された3Dモデルを表示するレンダリング済みプレビュー。 |
| `task_id` | string \| null | 生成されたモデルを識別する再利用可能なTripoタスクID。これにより、モデルを再アップロードせずにrigまたはrig-checkを実行できます。 |
