# Hyper3D - Rodin V2.5 - Image to 3D API

> 使用 Rodin V2.5 进行图像转 3D，最多支持 5 张参考图像并可选择质量等级

根据 `image_urls` 中的一到五张图像构建 3D 模型，可选最多 1024 个字符的 `prompt`。六个等级从 Gen-2.5-Minimum 到 Gen-2.5-Extreme-High，默认 High。选项包括几何格式（glb、usdz、fbx、obj、stl）、`material`、四边形或三角形网格尺寸、适合绑定角色的 `TAPose` 以及 `hd_texture`。

- Model id: `hyper3d/rodin/v2.5`
- Made by: Hyper3D
- Category: Image to 3D
- Output: 3d
- Price: from $0.40 / request (cheapest run $0.40 (400 API credits))
- Run: `POST https://api.doitong.com/v1/run/hyper3d/rodin/v2.5`
- Quote: `POST https://api.doitong.com/v1/quote/hyper3d/rodin/v2.5`
- Docs page: https://doitong.com/zh/developers/models/hyper3d/rodin/v2.5

## Pricing

Price: **from $0.40 / request** (the lowest tier; the quote prices your exact input). Billed once per request.

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `addons.high_pack` = true: $1.20 (1200 API credits) / 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/v2.5` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | no | `` | ≤ 1024 characters | 使用文本指导生成，或在 Image-to-3D 模式下留空，让模型根据图像自动推导提示词。 |
| `image_urls` | `images` | array of image URL | no |  | 1 – 5 items | 源图像 URL，最多支持 5 张图像；在 Image-to-3D 模式下为必填，用于生成模型。 |
| `tier` |  | enum (string) | no | `Gen-2.5-High` | `Gen-2.5-Minimum`, `Gen-2.5-Extreme-Low`, `Gen-2.5-Low`, `Gen-2.5-Medium`, `Gen-2.5-High`, `Gen-2.5-Extreme-High` | 网格细节层级；提高层级会增加细节，但 Gen-2.5-Minimum 会自动启用 minimum 模式，并无论 quality_mesh_option 如何都强制使用 50K Triangle。更多详情请参阅[文档](https://developer.hyper3d.ai/api-specification/rodin-gen2.5#use-gen-2.5-generation-with-following-gen-2.5-tiers)。 |
| `use_original_alpha` |  | boolean | no | `false` |  | 控制生成 3D 内容时是否保留输入图像的透明度通道。 |
| `seed` |  | integer \| null | no |  | 0 – 65,535 | 可选的随机化种子，范围为 0–65535。 |
| `geometry_file_format` |  | enum (string) | no | `glb` | `glb`, `usdz`, `fbx`, `obj`, `stl` | 几何文件格式，可从 glb、usdz、fbx、obj、stl 中选择；默认值为 glb。 |
| `material` |  | enum (string) | no | `All` | `PBR`, `Shaded`, `All`, `None` | 材质输出选择：选择 None 可生成无纹理的几何体，选择 All 可获得两种材质变体。要使用基于物理的材质实现真实光照，请选择 PBR；要使用不含 PBR 贴图的烘焙光照，请选择 Shaded。 |
| `quality_mesh_option` |  | enum (string) | no | `Auto` | `Auto`, `4K Quad`, `8K Quad`, `18K Quad`, `50K Quad`, `100K Quad`, `200K Quad`, `2K Triangle`, `20K Triangle`, `50K Triangle`, `150K Triangle`, `500K Triangle`, `1M Triangle`, `2M Triangle` | 网格拓扑和质量；可用面数由层级决定：Extreme-Low、Low 和 Medium 最多支持 1M Triangle；High 和 Extreme-High 支持 20K Triangle 至 2M Triangle。Auto 应用以下推荐设置：1. Gen-2.5-Minimum → 50K Triangle；2. Gen-2.5-Extreme-Low → 50K Triangle；3. Gen-2.5-Low → 50K Triangle；4. Gen-2.5-Medium → 500K Triangle；5. Gen-2.5-High → 500K Triangle；Gen-2.5-Extreme-High → 1M Triangle。手动选择时，Quad 偏向平滑表面，Triangle 偏向细节丰富的几何体；Hyper3D API 接收的拓扑为 `mesh_mode`（Quad/Raw），面数为 `quality_override`。 |
| `texture_mode` |  | enum (string) \| null | no |  | `legacy`, `extreme-low`, `low`, `medium`, `high` | 显式选择纹理质量，或交由 API 选择；API 会使用适合该层级的默认值。 |
| `enable_creative_mode` |  | boolean | no | `false` |  | 创意生成模式，相当于在 Hyper3D API 中将 `geometry_instruct_mode` 设置为 `creative`。启用后可提高生成稳定性，同时不牺牲输出一致性。 |
| `hd_texture` |  | boolean | no | `false` |  | 控制高级纹理后处理，以改善视觉保真度。 |
| `texture_delight` |  | boolean | no | `false` |  | 从生成的纹理中去除烘焙的光照和高光。 |
| `is_micro` |  | boolean | no | `false` |  | 增加微观尺度的精细几何细节；仅当 `tier="Gen-2.5-Extreme-High"` 时生效。 |
| `TAPose` |  | boolean | no | `false` |  | 便于在 3D 软件中绑定和制作动画的角色姿势设置：启用后会以 T-pose 或 A-pose 生成角色。 |
| `bbox_condition` |  | object {width, height, length} \| null | no |  |  | 使用 ControlNet 限制生成模型的最大尺寸。 |
| `bbox_condition.width` |  | integer | no | `0` | 1 – 2,048 | 沿 x 轴的包围盒约束宽度。 |
| `bbox_condition.height` |  | integer | no | `0` | 1 – 2,048 | 沿 y 轴的包围盒约束高度。 |
| `bbox_condition.length` |  | integer | no | `0` | 1 – 2,048 | 沿 z 轴的包围盒约束长度。 |
| `addons` |  | object {high_pack} \| null | no |  |  | 可选的附加项选择；可以以列表形式提供，也可以在只有一个附加项时提供单个值。 |
| `addons.high_pack` |  | boolean | no | `false` |  | HighPack 增强：Quad 输出的面数约为通过 quality 参数请求数量的 16 倍，纹理使用 4K 分辨率而非默认的 2K。 |
| `preview_render` |  | boolean | no | `false` |  | 预览渲染开关；启用后会添加一张显示已生成 3D 模型的图像，并随模型文件一起交付。 |
| `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
{}
```

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/v2.5?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/v2.5?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/v2.5", 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/v2.5",
      "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.
