# Hyper3d API

> 최대 5개의 입력 이미지, 사각형 또는 삼각형 메시 프리셋 및 미리보기 렌더를 지원하는 Rodin v2 텍스트 또는 이미지-3D 변환

프롬프트(최대 1024자)와 `input_image_urls`의 이미지 최대 5개에서 3D 모델을 생성합니다. `quality_mesh_option`은 4K~50K의 사각형 메시와 2K~500K의 삼각형 메시를 제공합니다. `material`은 PBR, Shaded 또는 All, `TAPose`, `use_original_alpha` 및 `preview_render`를 지원합니다.

- Model id: `hyper3d/rodin/v2`
- Made by: Hyper3D
- Category: Image to 3D
- Output: 3d
- Price: $0.40 / request (cheapest run $0.40 (400 API credits))
- Run: `POST https://api.doitong.com/v1/run/hyper3d/rodin/v2`
- Quote: `POST https://api.doitong.com/v1/quote/hyper3d/rodin/v2`
- Docs page: https://doitong.com/ko/developers/models/hyper3d/rodin/v2

## Pricing

Price: **$0.40 / request**. Billed once per request.

The full example input below costs $0.40 = 400 API credits (1 request × 400 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/hyper3d/rodin/v2` 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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | no | `` | ≤ 1024 characters | 텍스트 프롬프트로 생성을 안내하거나, Image-to-3D 모드에서 비워 두어 AI가 이미지에서 프롬프트를 도출하도록 합니다. |
| `input_image_urls` |  | array of image URL | no |  |  | 모델 생성에 사용하는 소스 이미지 URL입니다. 최대 5개까지 가능하며 Image-to-3D 모드에서는 필수입니다. |
| `use_original_alpha` |  | boolean | no | `false` |  | 3D 콘텐츠 생성 시 입력 이미지의 투명도 채널을 유지할지 제어합니다. |
| `seed` |  | integer \| null | no |  | 0 – 65,535 | 0~65535 범위의 선택적 무작위 시드입니다. |
| `geometry_file_format` |  | enum (string) | no | `glb` | `glb`, `usdz`, `fbx`, `obj`, `stl` | glb, usdz, fbx, obj, stl 중 선택하는 형상 파일 형식이며, 기본값은 glb입니다. |
| `material` |  | enum (string) | no | `All` | `PBR`, `Shaded`, `All` | 재질 선택입니다. All은 두 대안을 모두 포함합니다. PBR은 사실적인 조명을 위해 물리 기반 방식을 사용하고, Shaded는 단순한 재질과 베이크된 조명을 사용합니다. |
| `quality_mesh_option` |  | enum (string) | no | `500K Triangle` | `4K Quad`, `8K Quad`, `18K Quad`, `50K Quad`, `2K Triangle`, `20K Triangle`, `150K Triangle`, `500K Triangle` | 결합된 메시 및 품질 선택입니다. Hyper3D API에서는 옵션의 숫자 부분을 사용해 `quality_override`에 매핑하고, 옵션에 'Triangle'이 포함되면 'Raw'를, 그렇지 않으면 'Quad'를 사용해 `mesh_mode`에 매핑합니다. Quad는 매끄러운 표면을, Triangle은 세밀한 형상을 우선합니다. |
| `TAPose` |  | boolean | no | `false` |  | 3D 소프트웨어에서 리깅과 애니메이션을 쉽게 하기 위한 캐릭터 포즈 설정입니다. 활성화하면 캐릭터를 T-pose 또는 A-pose로 생성합니다. |
| `bbox_condition` |  | array of integer \| null | no |  |  | 너비, 높이, 길이 순서의 배열로 표현한 경계 상자 크기입니다. |
| `addons` |  | string \| null | no |  |  | HighPack은 고폴리곤 모델을 제공하고 텍스처 해상도를 기본 1K에서 4K로 높입니다. |
| `preview_render` |  | boolean | no | `false` |  | 생성된 3D 모델을 보여 주는 이미지가 전달된 모델 파일에 추가되도록 하는 미리보기 렌더링 전환입니다. |

File parameters (`input_image_urls`) 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
{}
```

A fuller example:

```json
{
  "prompt": ""
}
```

## 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/hyper3d/rodin/v2?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": ""
  }'

# 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/hyper3d/rodin/v2?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": ""
  }),
});
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 = {
    "prompt": "",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/hyper3d/rodin/v2", 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": "hyper3d/rodin/v2",
      "input": {
        "prompt": ""
      },
      "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.
