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

> Conversion de texte en 3D avec Rodin V2.5 sur six niveaux, à partir d’un prompt de 1024 caractères maximum

Génère un modèle 3D à partir d’un `prompt` obligatoire de 1024 caractères maximum. Choisissez un `tier` de Gen-2.5-Minimum à Gen-2.5-Extreme-High (High par défaut), une taille de maillage en quadrilatères ou triangles et un `material` tel que PBR ou Shaded. Exportez en glb, usdz, fbx, obj ou stl et définissez `seed` entre 0 et 65535.

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

## 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.ru/v1/quote/hyper3d/rodin/v2.5/text-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 |
|---|---|---|---|---|---|---|
| `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-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` | Niveau de détail du maillage ; augmenter ce niveau ajoute des détails, mais Gen-2.5-Minimum active automatiquement le mode minimum et impose 50K Triangle, quelle que soit la valeur de quality_mesh_option. Plus de détails figurent dans la [documentation](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 aléatoire facultative comprise entre 0 et 65535. |
| `geometry_file_format` |  | enum (string) | no | `glb` | `glb`, `usdz`, `fbx`, `obj`, `stl` | Format de fichier de géométrie, sélectionné parmi glb, usdz, fbx, obj et stl ; glb est utilisé par défaut. |
| `material` |  | enum (string) | no | `All` | `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 physiquement basés, choisissez PBR ; pour un éclairage précalculé sans cartes PBR, choisissez 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` | Topologie et qualité du maillage, avec un nombre de faces disponible déterminé par le niveau : Extreme-Low, Low et Medium autorisent jusqu'à 1M Triangle ; High et Extreme-High prennent en charge de 20K Triangle à 2M Triangle. Auto applique les réglages recommandés suivants : 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. Pour une sélection manuelle, Quad privilégie les surfaces lisses et Triangle la géométrie détaillée ; l'API Hyper3D reçoit la topologie dans `mesh_mode` (Quad/Raw) et le nombre de faces dans `quality_override`. |
| `texture_mode` |  | enum (string) \| null | no |  | `legacy`, `extreme-low`, `low`, `medium`, `high` | Choisissez explicitement la qualité des textures ou laissez l'API faire ce choix, avec 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 sacrifier la cohérence de la sortie. |
| `hd_texture` |  | boolean | no | `false` |  | Contrôle le post-traitement avancé des textures pour améliorer la fidélité visuelle. |
| `texture_delight` |  | boolean | no | `false` |  | Supprime l'éclairage et les reflets précalculés des textures générées. |
| `is_micro` |  | boolean | no | `false` |  | Ajoute des détails géométriques plus fins à l'échelle microscopique ; ne prend effet que 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 T ou 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 sur l'axe x. |
| `bbox_condition.height` |  | integer | no | `0` | 1 – 2,048 | Contrainte de hauteur de la boîte englobante sur l'axe y. |
| `bbox_condition.length` |  | integer | no | `0` | 1 – 2,048 | Contrainte de longueur de la boîte englobante sur l'axe z. |
| `addons` |  | object {high_pack} \| null | no |  |  | Options supplémentaires à appliquer, si nécessaire. |
| `addons.high_pack` |  | boolean | no | `false` |  | Amélioration HighPack : la sortie Quad possède environ 16 fois le nombre de faces demandé par le paramètre de qualité, et les textures utilisent une résolution 4K au lieu de la valeur par défaut 2K. |
| `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?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?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", 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",
      "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.
