# Meshy 6 Preview · Image to 3D API

> Meshy 6 Preview 图像转 3D，支持拓扑、面数、PBR、绑定骨骼和动画选项

通过 `image_url` 从单张图像创建 3D 模型。可选择 standard、lowpoly 或 smart-topology 网格、三角形或四边形拓扑，并将 `target_polycount` 设置为 100 至 300000。可通过 `texture_prompt` 或 `texture_image_url` 指导纹理生成；支持 PBR 贴图、姿态模式、人形绑定骨骼和动画预设。

- Model id: `meshy/v6-preview/image-to-3d`
- Made by: Meshy
- Category: Image to 3D
- Output: 3d
- Price per run: from $0.80 / run (cheapest run $0.80 (800 API credits))
- Run: `POST https://api.doitong.ru/v1/run/meshy/v6-preview/image-to-3d`
- Quote: `POST https://api.doitong.ru/v1/quote/meshy/v6-preview/image-to-3d`
- Docs page: https://doitong.com/zh/developers/models/meshy/v6-preview/image-to-3d

## Pricing

Price: **from $0.80 / 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 $1.20 = 1200 API credits (1 run × $1.20).

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/meshy/v6-preview/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 |  |  | 通过 URL 或 base64 data URI 提供用于创建 3D 模型的源图像，支持 .jpg、.jpeg、.png、AVIF 或 HEIF。AVIF 和 HEIF 输入会自动转换。 |
| `model_type` |  | enum (string) | no | `standard` | `standard`, `lowpoly`, `smart-topology` | 3D 网格模式：选择 'lowpoly' 可获得针对更整洁多边形优化的低多边形结果；在此模式下 Meshy 会忽略 topology、target_polycount 和 should_remesh。要获得常规高细节结果，请选择 'standard'；或选择 'smart-topology'，使用 Meshy-T2 从一开始分别生成整洁部件。 |
| `topology` |  | enum (string) | no | `triangle` | `quad`, `triangle` | 模型拓扑选项：Triangle 用于几何细节，Quad 用于表面平滑度。 |
| `target_polycount` |  | integer | no | `30000` | 100 – 300,000 | 多边形数量目标；当 model_type 为 'smart-topology' 时上限为 15,000。在该模式下省略目标值会选择 Meshy 较低的默认值 4,000。 |
| `symmetry_mode` |  | enum (string) | no | `auto` | `off`, `auto`, `on` | 选择模型生成是否使用 On 强制对称、使用 Off 不启用对称，或使用 Auto 自动决定。 |
| `should_remesh` |  | boolean | no | `true` |  | 启用或禁用重网格阶段。 |
| `should_texture` |  | boolean | no | `true` |  | 启用或禁用纹理生成。 |
| `enable_pbr` |  | boolean | no | `false` |  | 在基础色旁添加金属度、粗糙度和法线 PBR 贴图。 |
| `is_a_t_pose` |  | boolean | no | `false` |  | 设为 true 时启用 T-pose 生成；已弃用，改用 pose_mode。 |
| `pose_mode` |  | enum (string) | no | `` | `a-pose`, `t-pose`, `` | 将字符串留空表示不指定生成模型的姿势，或使用 'a-pose' 请求 A-pose，使用 't-pose' 请求 T-pose。 |
| `texture_prompt` |  | string \| null | no |  | ≤ 600 characters | 指导纹理生成的文本指令。 |
| `texture_image_url` |  | string (image URL) \| null | no |  |  | 指导纹理生成的 2D 参考图像。 |
| `enable_rigging` |  | boolean | no | `false` |  | 自动人形绑定骨骼，最适合四肢清晰可辨的人形模型。启用后会为生成的模型绑定骨骼，并提供基本的行走和跑步动画。 |
| `rigging_height_meters` |  | number | no | `1.7` | > 0 | 当 enable_rigging 为 true 时，以米为单位提供估计的角色高度；否则此值无效。 |
| `enable_animation` |  | boolean | no | `false` |  | 是否为已绑定骨骼的模型应用预设动画；需要 enable_rigging 为 true。 |
| `animation_action_id` |  | integer | no | `92` |  | Meshy 动画库预设 ID，可用动作列于 https://docs.meshy.ai/en/api/animation-library。仅当 enable_animation 为 true 时才会进行验证和使用：超出 [0, 696] 的值会以 422 拒绝，且 "Idle" 对应 `0`。 |
| `enable_safety_checker` |  | boolean | no | `true` |  | 预处理安全检查开关：true 表示必须先通过输入安全检查才能处理。 |

File parameters (`image`, `texture_image_url`) 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/meshy/v6-preview/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/meshy/v6-preview/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/meshy/v6-preview/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": "meshy/v6-preview/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.
