## Pricing

Price: **$0.10 / request**. Billed once per request.

The full example input below costs $0.10 = 100 API credits (1 request × 100 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.ru/v1/quote/hyper3d/rodin/v2.5/text-to-3d/fast` 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 | yes |  | ≤ 1024 characters | Instructions textuelles guidant la génération du modèle ; obligatoires en mode Text-to-3D. |
| `tier` |  | enum (string) | no | `Gen-2.5-Extreme-Low` | `Gen-2.5-Minimum`, `Gen-2.5-Extreme-Low`, `Gen-2.5-Low` | Niveau de génération ; Gen-2.5-Minimum impose le mode minimum et un maillage 50K Triangle, quelle que soit la valeur de `quality_mesh_option`. Les détails des niveaux sont disponibles dans la [documentation Hyper3D](https://developer.hyper3d.ai/api-specification/rodin-gen2.5#use-gen-2.5-generation-with-following-gen-2.5-tiers). |
| `seed` |  | integer \| null | no |  | 0 – 65,535 | Graine de randomisation facultative, comprise entre 0 et 65535. |
| `geometry_file_format` |  | enum (string) | no | `glb` | `glb`, `usdz`, `fbx`, `obj`, `stl` | Format de fichier géométrique, choisi parmi glb, usdz, fbx, obj, stl ; glb est utilisé par défaut. |
| `material` |  | enum (string) | no | `Shaded` | `PBR`, `Shaded`, `All`, `None` | Sélection de la sortie des matériaux : choisissez None pour une géométrie sans textures, ou All pour recevoir les deux variantes de matériaux. Pour un éclairage réaliste avec des matériaux basés sur la physique, choisissez PBR ; pour un éclairage précalculé sans cartes PBR, choisissez Shaded. |
| `quality_mesh_option` |  | enum (string) | no | `Auto` | `Auto`, `1K Quad`, `4K Quad`, `8K Quad`, `18K Quad`, `20K Quad`, `2K Triangle`, `4K Triangle`, `8K Triangle`, `10K Triangle`, `20K Triangle` | Choisissez la qualité avec la topologie du maillage : Quad privilégie les surfaces lisses, tandis que Triangle privilégie les détails géométriques. Le point de terminaison rapide est principalement destiné aux tests et au prototypage, avec une limite de 20K ; utilisez le point de terminaison standard pour des maillages de meilleure qualité, où Minimum, Extreme-Low et Low prennent en charge jusqu'à 1M Triangle, avec un nombre de faces disponible dépendant du niveau. Dans l'API Hyper3D, `quality_override` spécifie le nombre de faces, tandis que `mesh_mode` spécifie Quad/Raw. Auto sélectionne les paramètres recommandés : 1. Gen-2.5-Minimum → 20K Triangle ; 2. Gen-2.5-Extreme-Low → 20K Triangle ; 3. Gen-2.5-Low → 20K Triangle. |
| `texture_mode` |  | enum (string) \| null | no |  | `legacy`, `extreme-low`, `low`, `medium`, `high` | Choisissez explicitement la qualité des textures ou laissez l'API effectuer ce choix ; elle utilise une valeur par défaut adaptée au niveau. |
| `enable_creative_mode` |  | boolean | no | `false` |  | Mode de génération créative, équivalent à `geometry_instruct_mode` défini sur `creative` dans l'API Hyper3D. Son activation rend la génération plus robuste sans compromettre la cohérence de la sortie. |
| `hd_texture` |  | boolean | no | `false` |  | Contrôle le post-traitement avancé des textures afin d'améliorer la fidélité visuelle. |
| `texture_delight` |  | boolean | no | `false` |  | Supprime l'illumination et les reflets précalculés des textures générées. |
| `is_micro` |  | boolean | no | `false` |  | Ajoute des détails géométriques plus fins à l'échelle microscopique ; prend effet uniquement lorsque `tier="Gen-2.5-Extreme-High"`. |
| `TAPose` |  | boolean | no | `false` |  | Paramètre de pose du personnage pour faciliter le rigging et l'animation dans les logiciels 3D : son activation génère les personnages en pose en T ou en A. |
| `bbox_condition` |  | object {width, height, length} \| null | no |  |  | Limite la taille maximale du modèle généré à l'aide d'un ControlNet. |
| `bbox_condition.width` |  | integer | no | `0` | 1 – 2,048 | Contrainte de largeur de la boîte englobante le long de l'axe x. |
| `bbox_condition.height` |  | integer | no | `0` | 1 – 2,048 | Contrainte de hauteur de la boîte englobante le long de l'axe y. |
| `bbox_condition.length` |  | integer | no | `0` | 1 – 2,048 | Contrainte de longueur de la boîte englobante le long de l'axe z. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Le filtrage peut être assoupli en définissant false, si l'appelant est autorisé. |

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/hyper3d/rodin/v2.5/text-to-3d/fast?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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/hyper3d/rodin/v2.5/text-to-3d/fast?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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 = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# 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/text-to-3d/fast", 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": "hyper3d/rodin/v2.5/text-to-3d/fast",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
