# Hunyuan 3D Pro Image to 3D API

> Huunda modeli ya 3D kutoka picha ya mbele pamoja na mitazamo ya ziada ya hiari, ikiwa na udhibiti wa idadi ya nyuso na PBR

Huunda modeli ya 3D kutoka kwenye picha ya mbele inayohitajika, `input_image_url`. Mitazamo ya hiari ya nyuma, kushoto, kulia, juu, chini na miwili ya nyuzi 45 inaweza kuongeza maelezo. `generate_type` huchagua modeli yenye tekstura au ya jiometri nyeupe pekee, `enable_pbr` huongeza nyenzo za PBR, na `face_count` huanzia 40,000 hadi 1,500,000. Hurudisha GLB, URL za miundo mingine na kijipicha.

## Pricing

Price: **$0.375 / run**. 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 $0.375 = 375 API credits (1 run × $0.375).

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/hunyuan-3d/v3.1/pro/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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `input_image_url` |  | string (image URL) | yes |  |  | URL ya picha ya JPG, PNG au WEBP ya mwonekano wa mbele, yenye mwonekano kutoka 128 hadi 5000px na ukubwa usiozidi 8 MB. Pendelea mandharinyuma rahisi na kitu kimoja kinachojaza zaidi ya 50% ya fremu. |
| `back_image_url` |  | string (image URL) \| null | no |  |  | URL ya picha ya mwonekano wa nyuma, ya hiari; JPG/PNG inapendekezwa. |
| `left_image_url` |  | string (image URL) \| null | no |  |  | URL ya picha ya mwonekano wa kushoto, ya hiari; JPG/PNG inapendekezwa. |
| `right_image_url` |  | string (image URL) \| null | no |  |  | URL ya picha ya mwonekano wa kulia, ya hiari; JPG/PNG inapendekezwa. |
| `top_image_url` |  | string (image URL) \| null | no |  |  | URL ya picha ya mwonekano wa juu, ya hiari na inayopatikana tu katika v3.1; JPG/PNG inapendekezwa. |
| `bottom_image_url` |  | string (image URL) \| null | no |  |  | URL ya picha ya hiari ya mwonekano wa chini, inayotumika tu katika v3.1. JPG/PNG inapendekezwa. |
| `left_front_image_url` |  | string (image URL) \| null | no |  |  | URL ya picha ya hiari inayopatikana tu katika v3.1, ikiwezekana katika umbizo la JPG/PNG. Picha hutoa mwonekano wa digrii 45 kutoka mbele kushoto. |

File parameters (`input_image_url`, `back_image_url`, `left_image_url`, `right_image_url`, `top_image_url`, `bottom_image_url`, `left_front_image_url`, `right_front_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
{
  "input_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json

}
```

## 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/hunyuan-3d/v3.1/pro/image-to-3d?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "input_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/hunyuan-3d/v3.1/pro/image-to-3d?wait=20", {
  method: "POST",
  headers,

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 = {
    "input_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/hunyuan-3d/v3.1/pro/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": "hunyuan-3d/v3.1/pro/image-to-3d",
      "input": {
        "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.
