# Tripo H3.1 Text to 3D API

> Negatif isteme, ayrı geometri ve doku kalitesi katmanlarına ve çok yüksek yüz sınırına sahip text-to-3D poligon ağı üreticisi

En fazla 1024 karakterlik metin açıklamasından, kaçınılacak özellikler için isteğe bağlı bir `negative_prompt` ile 3D model oluşturur. `face_limit` 1,000 ile 2,000,000 yüz arasını kabul eder. `geometry_quality` ve `texture_quality` ayrı ayrı standart veya ayrıntılı olabilir. Seçenekler arasında PBR materyalleri, dörtgen topoloji, gerçek dünya boyutuna otomatik ölçekleme ve geometri, text-to-image adımı ile doku için ayrı tohumlar bulunur.

## Pricing

Price: **from $0.10 / 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 $0.20 = 200 API credits (1 run × $0.20).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.ru/v1/quote/tripo3d/h3.1/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 | İstenen 3D nesnenin 1024 karakterle sınırlı metin açıklaması. |
| `negative_prompt` |  | string \| null | no |  | ≤ 1024 characters | Üretilen modelden hariç tutulması gereken özelliklerin açıklaması. |
| `face_limit` |  | integer \| null | no |  | 1,000 – 2,000,000 | Sağlandığında modelin uyarlamalı sayı seçimini geçersiz kılan, mesh üretimi için açık köşe sayısı hedefi. |
| `texture` |  | boolean | no | `true` |  | Modelin üretilen dokuları alıp almayacağını belirler. |
| `pbr` |  | boolean | no | `true` |  | PBR malzemelerini (Fizik Tabanlı İşleme) etkinleştirir; true olduğunda doku üretimini de açar. |
| `model_seed` |  | integer \| null | no |  |  | Geometri üretiminin yeniden üretilebilir olmasını sağlayan tohum. |
| `image_seed` |  | integer \| null | no |  |  | Metinden görsele aşamasında kullanılan tohum. |
| `texture_seed` |  | integer \| null | no |  |  | Doku üretiminin yeniden üretilebilir olmasını sağlayan tohum. |
| `texture_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | Doku kalitesi ayarı; 'detailed' seçildiğinde doku çözünürlüğü artar. |
| `geometry_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | Geometri için kalite ayarı. |
| `auto_size` |  | boolean | no | `false` |  | Modele metre cinsinden gerçek dünya boyutları vermek için otomatik ölçeklendirme. |
| `quad` |  | boolean | no | `false` |  | Quad topolojisini etkinleştirerek üçgen yüzler ile 4 kenarlı dörtgenler arasında seçim yapın. Quad sonuçları için Tripo verileri FBX baytları olarak sağladığında bir FBX dosyası döndürülür. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Çağıran yetkiliyse false ayarlanarak tarama gevşetilebilir. |

}
```

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/tripo3d/h3.1/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/tripo3d/h3.1/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/tripo3d/h3.1/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": "tripo3d/h3.1/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.
