# Meshy V7 Text to 3D API

> Texto a 3D con Meshy 7: modo de previsualización o completo, geometría 2k y opciones de PBR, rig y animación

Genera un modelo 3D a partir de un `prompt` de hasta 600 caracteres, con `enable_prompt_expansion` opcional. `mode` devuelve geometría sin texturas o un modelo texturizado. Elige standard, lowpoly o smart-topology mediante `model_type`, establece `target_polycount` de 100 a 300000 y selecciona standard o 2k en `geometry_resolution`. Se pueden añadir rig y presets de animación a personajes humanoides.

## Pricing

Price: **from $0.80 / 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 $1.20 = 1200 API credits (1 run × $1.20).

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/meshy/v7/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 |  | ≤ 600 characters | Descripción del objeto que se representará como modelo 3D, limitada a 600 caracteres. |
| `mode` |  | enum (string) | no | `full` | `preview`, `full` | Modo de generación: 'preview' produce geometría sin texturas, mientras que 'full' produce un modelo texturizado combinando preview y refine. |
| `seed` |  | integer \| null | no |  |  | Reutiliza esta semilla junto con un prompt sin cambios para reproducir normalmente un resultado anterior. |
| `model_type` |  | enum (string) | no | `standard` | `standard`, `lowpoly`, `smart-topology` | Modo de malla 3D: elige 'lowpoly' para obtener un resultado de pocos polígonos optimizado para polígonos más limpios; en este modo Meshy ignora topology, target_polycount y should_remesh. Para un resultado convencional de gran detalle, elige 'standard', o elige 'smart-topology' para usar Meshy-T2 durante la etapa de geometría (preview) y obtener piezas limpias generadas por separado desde el principio. |
| `topology` |  | enum (string) | no | `triangle` | `quad`, `triangle` | Elección de topología del modelo entre Triangle para el detalle geométrico y Quad para la suavidad de la superficie. |
| `target_polycount` |  | integer | no | `30000` | 100 – 300,000 | Objetivo de cantidad de polígonos, limitado a 15,000 cuando model_type es 'smart-topology'. Omitir el objetivo en ese modo selecciona el valor predeterminado inferior de Meshy: 4,000. |
| `should_remesh` |  | boolean | no | `true` |  | Omite el remallado y recibe la malla triangular sin procesar al establecerlo en false; de lo contrario, activa la fase de remallado. |
| `symmetry_mode` |  | enum (string) | no | `auto` | `off`, `auto`, `on` | Configuración de simetría aplicada durante la generación del modelo. |
| `enable_pbr` |  | boolean | no | `false` |  | Controla la generación de mapas PBR metálico, rugosidad y normales junto al color base. |
| `is_a_t_pose` |  | boolean | no | `false` |  | Interruptor de generación en pose T activado por true; obsoleto en favor de pose_mode. |
| `pose_mode` |  | enum (string) | no | `` | `a-pose`, `t-pose`, `` | Deja la cadena vacía para no especificar la pose del modelo generado, o solicita una pose A con 'a-pose' o una pose T con 't-pose'. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Permite que un modelo de lenguaje grande enriquezca el prompt con detalles. Activar esta expansión no cambia el significado del prompt. |
| `texture_prompt` |  | string \| null | no |  | ≤ 600 characters | Guía el texturizado con un prompt de texto adicional en el modo 'full'; los demás modos no lo utilizan. |
| `texture_image_url` |  | string (image URL) \| null | no |  |  | Imagen de referencia 2D para la generación de texturas, aplicada solo en el modo 'full'. |
| `enable_rigging` |  | boolean | no | `false` |  | Rigging humanoide automático, más eficaz para modelos humanoides cuyas extremidades se distinguen claramente. Al activarlo, aplica rigging al modelo generado y proporciona animaciones básicas de caminar y correr. |
| `rigging_height_meters` |  | number | no | `1.7` | > 0 | Proporciona una altura estimada del personaje en metros cuando enable_rigging sea true; de lo contrario, este valor no tiene efecto. |
| `enable_animation` |  | boolean | no | `false` |  | Indica si el modelo con rigging recibe una animación preestablecida, lo que requiere que enable_rigging sea true. |
| `animation_action_id` |  | integer | no | `92` |  | ID de la animación preestablecida de la biblioteca de Meshy, con las acciones disponibles enumeradas en https://docs.meshy.ai/en/api/animation-library. La validación y el uso solo se aplican cuando enable_animation es true: los valores fuera de [0, 696] se rechazan con un 422 y "Idle" corresponde a `0`. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Interruptor de comprobación de seguridad del preprocesamiento: true hace que una comprobación de seguridad de la entrada sea un requisito previo al procesamiento. |
| `geometry_resolution` |  | enum (string) \| null | no |  | `standard`, `2k` | Resolución de la geometría de la malla; las opciones compatibles de Meshy-7 son standard y 2k. |
| `ultra_mode` |  | boolean | no | `false` |  | Opción obsoleta reemplazada por geometry_resolution, que prevalece si se proporcionan ambas; usa geometry_resolution='2k' en su lugar. |

File parameters (`texture_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

```

## 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/meshy/v7/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.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/meshy/v7/text-to-3d?wait=20", {

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": "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/meshy/v7/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.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": "meshy/v7/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.
