# Meshy 6 · Text to 3D API

> Generatore di mesh testo-3D con modalità preview o texturizzata, PBR, rigging e animazione opzionali

Costruisce un modello 3D da un `prompt` testuale di massimo 600 caratteri. `mode` sceglie la geometria non texturizzata (`preview`) o un risultato texturizzato (`full`). `model_type` può essere standard, lowpoly o smart-topology e `target_polycount` varia da 100 a 300000, con smart topology limitata a 15000. Può inoltre aggiungere mappe PBR, una posa, rigging umanoide e un preset di animazione.

## Pricing

Price: **$0.80 / request**. Billed once per request.

The full example input below costs $0.80 = 800 API credits (1 request × 800 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/meshy/v6/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 | Descrizione dell'oggetto da rappresentare come modello 3D, limitata a 600 caratteri. |
| `mode` |  | enum (string) | no | `full` | `preview`, `full` | Modalità di generazione: 'preview' produce la geometria senza texture, mentre 'full' produce un modello texturizzato combinando preview e refine. |
| `seed` |  | integer \| null | no |  |  | Riutilizzare questo seed insieme a un prompt invariato per riprodurre generalmente un risultato precedente. |
| `model_type` |  | enum (string) | no | `standard` | `standard`, `lowpoly`, `smart-topology` | Modalità mesh 3D: scegliere 'lowpoly' per un risultato low-poly ottimizzato per poligoni più puliti; in questa modalità Meshy ignora topology, target_polycount e should_remesh. Per un risultato convenzionale ad alto dettaglio scegliere 'standard', oppure scegliere 'smart-topology' per usare Meshy-T2 durante la fase di geometria (preview) e ottenere parti pulite generate separatamente fin dall'inizio. |
| `topology` |  | enum (string) | no | `triangle` | `quad`, `triangle` | Scelta della topologia del modello tra Triangle per i dettagli geometrici e Quad per la levigatezza della superficie. |
| `target_polycount` |  | integer | no | `30000` | 100 – 300,000 | Obiettivo del numero di poligoni, limitato a 15,000 quando model_type è 'smart-topology'. Omettendo l'obiettivo in tale modalità si seleziona il valore predefinito inferiore di Meshy, pari a 4,000. |
| `should_remesh` |  | boolean | no | `true` |  | Saltare il remeshing e ricevere la mesh triangolare grezza impostando questo valore su false; altrimenti abilitare la fase di remesh. |
| `symmetry_mode` |  | enum (string) | no | `auto` | `off`, `auto`, `on` | Impostazione della simmetria applicata durante la generazione del modello. |
| `enable_pbr` |  | boolean | no | `false` |  | Controlla la generazione delle mappe PBR metallic, roughness e normal insieme al colore di base. |
| `is_a_t_pose` |  | boolean | no | `false` |  | Interruttore per la generazione della posa a T, attivato da true; obsoleto a favore di pose_mode. |
| `pose_mode` |  | enum (string) | no | `` | `a-pose`, `t-pose`, `` | Lasciare la stringa vuota per non specificare la posa del modello generato, oppure richiedere una posa ad A con 'a-pose' o una posa a T con 't-pose'. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Consente a un modello linguistico di grandi dimensioni di arricchire il prompt con dettagli. L'abilitazione di questa espansione lascia invariato il significato del prompt. |
| `texture_prompt` |  | string \| null | no |  | ≤ 600 characters | Guidare la texturizzazione con un prompt testuale aggiuntivo in modalità 'full'; le altre modalità non lo utilizzano. |
| `texture_image_url` |  | string (image URL) \| null | no |  |  | Immagine di riferimento 2D per la generazione delle texture, applicata solo in modalità 'full'. |
| `enable_rigging` |  | boolean | no | `false` |  | Rigging umanoide automatico, più efficace per modelli umanoidi i cui arti siano chiaramente distinguibili. Abilitandolo si applica il rigging al modello generato e si forniscono animazioni di base per camminata e corsa. |
| `rigging_height_meters` |  | number | no | `1.7` | > 0 | Fornire un'altezza stimata del personaggio in metri quando enable_rigging è true; altrimenti questo valore non ha effetto. |
| `enable_animation` |  | boolean | no | `false` |  | Indica se il modello sottoposto a rigging riceve un'animazione preimpostata, che richiede enable_rigging impostato su true. |
| `animation_action_id` |  | integer | no | `92` |  | ID del preset di animazione della libreria Meshy, con le azioni disponibili elencate all'indirizzo https://docs.meshy.ai/en/api/animation-library. La convalida e l'utilizzo si applicano solo quando enable_animation è true: i valori esterni a [0, 696] vengono rifiutati con un 422 e "Idle" corrisponde a `0`. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Interruttore del controllo di sicurezza preliminare: true rende il controllo di sicurezza dell'input un prerequisito per l'elaborazione. |

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`.

## 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/v6/text-to-3d?wait=20" \

### 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",

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/v6/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.
