# Tripo H3.1 Image to 3D API

> Генерация 3D из одного изображения с PBR-материалами, квад-сетками и управлением числом граней

Создаёт 3D-модель из одного изображения по адресу `image_url`. Доступны `face_limit` (от 1,000 до 2,000,000), `texture`, `pbr`, стандартное или детальное качество `texture_quality` и `geometry_quality`, топология `quad`, `auto_size` и `orientation`. Результат включает превью-рендер и ID задачи для последующего риггинга.

- Model id: `tripo3d/h3.1/image-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/image-to-3d`
- Quote: `POST https://api.doitong.ru/v1/quote/tripo3d/h3.1/image-to-3d`
- Docs page: https://doitong.ru/ru/developers/models/tripo3d/h3.1/image-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/image-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_url` | `image` | string (image URL) | yes |  |  | URL входного изображения для создания 3D-модели. |
| `face_limit` |  | integer \| null | no |  | 1,000 – 2,000,000 | Явно заданное целевое количество граней для генерации сетки, заменяющее адаптивный выбор количества моделью. |
| `texture` |  | boolean | no | `true` |  | Определяет, получает ли модель сгенерированные текстуры. |
| `pbr` |  | boolean | no | `true` |  | Включает материалы PBR (Physically Based Rendering), что также включает генерацию текстур при значении true. |
| `model_seed` |  | integer \| null | no |  |  | Сид, используемый для воспроизводимости генерации геометрии. |
| `texture_seed` |  | integer \| null | no |  |  | Сид, используемый для воспроизводимости генерации текстур. |
| `texture_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | Настройка качества текстур; выбор 'detailed' повышает разрешение текстур. |
| `geometry_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | Настройка качества геометрии. |
| `texture_alignment` |  | enum (string) | no | `original_image` | `original_image`, `geometry` | Ориентир для выравнивания текстур: используйте 'geometry' для сгенерированной геометрии или 'original_image' для входного изображения. |
| `auto_size` |  | boolean | no | `false` |  | Автоматическое масштабирование для задания реальных размеров модели в метрах. |
| `orientation` |  | enum (string) | no | `default` | `default`, `align_image` | Ориентация модели; 'align_image' автоматически поворачивает её в соответствии с входным изображением. |
| `quad` |  | boolean | no | `false` |  | Выбор между треугольными гранями и четырёхугольниками с помощью топологии quad. Для результатов с quad возвращается файл FBX, если Tripo предоставляет данные в виде байтов FBX. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Проверку можно ослабить, установив false, если вызывающая сторона авторизована. |

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.ru/v1/run/tripo3d/h3.1/image-to-3d?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.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/image-to-3d?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.ru/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/h3.1/image-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/image-to-3d",
      "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.

### Output fields (`output`)

| Field | Type | Description |
