# Hunyuan 3D Pro Image to 3D API

> Sukuria 3D modelį iš priekinio vaizdo ir pasirenkamų papildomų vaizdų, valdant paviršių skaičių ir PBR

Sukuria 3D modelį iš privalomo priekinio vaizdo `input_image_url`. Papildomi galiniai, kairysis, dešinysis, viršutinis, apatinis ir du 45 laipsnių vaizdai gali suteikti daugiau detalių. `generate_type` pasirenka tekstūruotą arba baltą, tik geometrijos modelį, `enable_pbr` prideda PBR medžiagas, o `face_count` svyruoja nuo 40,000 iki 1,500,000. Grąžinamas GLB, kitų formatų URL ir miniatiūra.

## 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 |  |  | Priekinio vaizdo JPG, PNG arba WEBP vaizdo URL; raiška nuo 128 iki 5000px, dydis ne didesnis nei 8 MB. Rekomenduojamas paprastas fonas ir vienas objektas, užpildantis daugiau nei 50% kadro. |
| `back_image_url` |  | string (image URL) \| null | no |  |  | Galiniame vaizde esančio vaizdo URL, pasirenkamas; rekomenduojamas JPG/PNG. |
| `left_image_url` |  | string (image URL) \| null | no |  |  | Kairiojo vaizdo URL, pasirenkamas; rekomenduojamas JPG/PNG. |
| `right_image_url` |  | string (image URL) \| null | no |  |  | Dešiniojo vaizdo URL, pasirenkamas; rekomenduojamas JPG/PNG. |
| `top_image_url` |  | string (image URL) \| null | no |  |  | Vaizdo iš viršaus URL, pasirenkamas ir pasiekiamas tik v3.1; rekomenduojamas JPG/PNG. |
| `bottom_image_url` |  | string (image URL) \| null | no |  |  | Pasirenkamo vaizdo iš apačios URL, palaikomas tik v3.1. Rekomenduojamas JPG/PNG. |
| `left_front_image_url` |  | string (image URL) \| null | no |  |  | Pasirenkamas vaizdo URL, pasiekiamas tik v3.1, pageidautina JPG/PNG formatu. Vaizdas pateikia 45 laipsnių kairiojo priekinio vaizdo perspektyvą. |
| `right_front_image_url` |  | string (image URL) \| null | no |  |  | Pasirenkamas vaizdo URL, pasiekiamas tik v3.1, pageidautina JPG/PNG formatu. Vaizdas pateikia 45 laipsnių dešiniojo priekinio vaizdo perspektyvą. |
| `generate_type` |  | enum (string) | no | `Normal` | `Normal`, `Geometry` | Pasirinkite tekstūruotą modelį su Normal arba netekstūruotą, tik geometrijos, baltą modelį su Geometry. V3.1 versijoje LowPoly/Sketch pasirinkti negalima. |
| `enable_pbr` |  | boolean | no | `false` |  | PBR generavimo perjungiklis, neaktyvus, kai generate_type yra Geometry. Kitu atveju jį įjungus prie sugeneruotų medžiagų pridedamos metalo, šiurkštumo ir normalės tekstūros. |
| `face_count` |  | integer | no | `500000` | 40,000 – 1,500,000 | Pageidaujamas daugiakampių paviršių skaičius nuo 40,000 iki 1,500,000. Numatytoji reikšmė – 500,000. |

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
{
  "input_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/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,
  body: JSON.stringify({
    "input_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 = {
    "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.
