# Hyper3D Rodin API

> Génération 3D Rodin à partir de texte ou d’images, avec matériaux PBR ou ombrés et niveaux de qualité

Génère des modèles 3D à partir d’une invite de jusqu’à 1024 caractères, d’images d’entrée ou des deux. `condition_mode` vaut fuse ou concat pour les entrées mult images. Les options comprennent `quality` de extra-low à high, `material` PBR ou Shaded, `tier` Regular ou Sketch, `TAPose`, `bbox_condition` et l’export glb, usdz, fbx, obj ou stl.

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

## Pricing

Price: **$0.40 / request**. Billed once per 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.com/v1/quote/hyper3d/rodin` 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 | no | `` | ≤ 1024 characters | Guidage de génération fourni sous forme de texte, requis par le mode Text-to-3D mais facultatif en mode Image-to-3D. |
| `input_image_urls` |  | array of image URL | no |  |  | URL des images sources, requises par Image-to-3D et pouvant être utilisées facultativement par Text-to-3D pour générer le modèle. |
| `condition_mode` |  | enum (string) | no | `concat` | `fuse`, `concat` | Méthode de conditionnement d'image: concat construit le modèle à partir de plusieurs vues d'un même objet, sans ordre d'envoi requis. fuse nécessite plutôt une ou plusieurs images et crée le modèle en extrayant les caractéristiques de l'objet et en les combinant entre les images. |
| `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, choisi parmi glb, usdz, fbx, obj et stl; glb est utilisé par défaut. |
| `material` |  | enum (string) | no | `PBR` | `PBR`, `Shaded` | Sélection du matériau: PBR ou Shaded, PBR étant la valeur par défaut. |
| `quality` |  | enum (string) | no | `medium` | `high`, `medium`, `low`, `extra-low` | Niveau de qualité de la génération: high, medium, low, extra-low; medium est utilisé par défaut. |
| `use_hyper` |  | boolean | no | `false` |  | Contrôle l'exportation du modèle en mode hyper; false est utilisé par défaut. |
| `tier` |  | enum (string) | no | `Regular` | `Regular`, `Sketch` | Sélection du niveau de génération: utilisez Sketch pour Rodin Sketch ou Regular pour Rodin Regular. |
| `TAPose` |  | boolean | no | `false` |  | Contrôle la génération d'un modèle humanoïde en pose T/A. |
| `bbox_condition` |  | array of integer \| null | no |  |  | Tableau de boîte englobante, généralement organisé en 3 entrées: longueur sur l'axe X, largeur sur l'axe Y et hauteur sur l'axe Z. Ces valeurs précisent les dimensions et le facteur d'échelle de la boîte. |
| `addons` |  | string \| null | no |  |  | Modules complémentaires de génération facultatifs; [] est utilisé par défaut. L'option HighPack disponible fournit des modèles haute densité et augmente la résolution des textures de 1K à 4K. |

File parameters (`input_image_urls`) 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
{}
```

A fuller example:

```json
{
  "prompt": ""
}
```

## 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.com/v1/run/hyper3d/rodin?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": ""
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/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?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": ""
  }),
});
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.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/hyper3d/rodin", 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.com/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",
      "input": {
        "prompt": ""
      },
      "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.
