# Tripo H3.1 Image to 3D API

> Generación 3D a partir de una sola imagen con materiales PBR, mallas quad y control del número de caras

Crea un modelo 3D a partir de una imagen en `image_url`. Las opciones incluyen `face_limit` (de 1,000 a 2,000,000), `texture`, `pbr`, `texture_quality` y `geometry_quality` estándar o detallada, topología `quad`, `auto_size` y `orientation`. El resultado incluye un renderizado de vista previa y un ID de tarea para el rigging posterior.

- Model id: `tripo3d/h3.1/image-to-3d`
- Made by: Tripo
- Category: Image to 3D
- Output: 3d
- Price per run: from $0.20 / run (cheapest run $0.20 (200 API credits))
- Run: `POST https://api.doitong.ru/v1/run/tripo3d/h3.1/image-to-3d`
- Quote: `POST https://api.doitong.ru/v1/quote/tripo3d/h3.1/image-to-3d`
- Docs page: https://doitong.com/es-ES/developers/models/tripo3d/h3.1/image-to-3d

## Pricing

Price: **from $0.20 / run** (the lowest tier; the quote prices your exact input). 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 $0.30 = 300 API credits (1 run × $0.30).

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/tripo3d/h3.1/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

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `image_url` | `image` | string (image URL) | yes |  |  | URL de la imagen de entrada usada para crear un modelo 3D. |
| `face_limit` |  | integer \| null | no |  | 1,000 – 2,000,000 | Objetivo explícito de número de caras para la generación de la malla, que sustituye la selección adaptativa del número por parte del modelo cuando se proporciona. |
| `texture` |  | boolean | no | `true` |  | Controla si el modelo recibe texturas generadas. |
| `pbr` |  | boolean | no | `true` |  | Activa los materiales PBR (Physically Based Rendering), lo que también activa la generación de texturas cuando es true. |
| `model_seed` |  | integer \| null | no |  |  | Semilla utilizada para hacer reproducible la generación de geometría. |
| `texture_seed` |  | integer \| null | no |  |  | Semilla utilizada para hacer reproducible la generación de texturas. |
| `texture_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | Ajuste de calidad de la textura; elegir 'detailed' aumenta la resolución de la textura. |
| `geometry_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | Ajuste de calidad de la geometría. |
| `texture_alignment` |  | enum (string) | no | `original_image` | `original_image`, `geometry` | Referencia de alineación de la textura: usa 'geometry' para la geometría generada o 'original_image' para la imagen de entrada. |
| `auto_size` |  | boolean | no | `false` |  | Escalado automático para proporcionar al modelo dimensiones del mundo real medidas en metros. |
| `orientation` |  | enum (string) | no | `default` | `default`, `align_image` | Orientación del modelo; 'align_image' lo gira automáticamente para que coincida con la imagen de entrada. |
| `quad` |  | boolean | no | `false` |  | Elige entre caras triangulares y cuadriláteros de 4 lados activando la topología de cuadriláteros. Para resultados con cuadriláteros, se devuelve un archivo FBX cuando Tripo proporciona los datos como bytes FBX. |
| `enable_safety_checker` |  | boolean | no | `true` |  | La moderación puede relajarse estableciendo false, siempre que la persona que realiza la solicitud esté autorizada. |

File parameters (`image`) 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
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "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/tripo3d/h3.1/image-to-3d?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "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/tripo3d/h3.1/image-to-3d?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "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 = {
    "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/tripo3d/h3.1/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": "tripo3d/h3.1/image-to-3d",
      "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.
