# Tripo H3.1 Text to 3D API

> Gineadóir mogall téacs-go-3D le leid dhiúltach, leibhéil ar leith do cháilíocht gheoiméadrachta agus uigeachta, agus uasteorainn an-ard aghaidheanna

Tógann sé samhail 3D ó chur síos téacs suas le 1024 carachtar, le `negative_prompt` roghnach do ghnéithe le seachaint. Glacann `face_limit` le 1,000 go 2,000,000 aghaidh. Is féidir `geometry_quality` agus `texture_quality` a bheith caighdeánach nó mionsonraithe. Áirítear ar na roghanna ábhair PBR, topolaíocht quad, uathscálú go méid an tsaoil réadaigh, agus síolta ar leith do gheoiméadracht, don chéim téacs-go-íomhá agus don uigeacht.

- Model id: `tripo3d/h3.1/text-to-3d`
- Made by: Tripo
- Category: Text to 3D
- Output: 3d
- Price per run: from $0.10 / run (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.ru/v1/run/tripo3d/h3.1/text-to-3d`
- Quote: `POST https://api.doitong.ru/v1/quote/tripo3d/h3.1/text-to-3d`

## 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 | Cur síos téacs ar an réad 3D inmhianaithe, teoranta do 1024 carachtar. |
| `negative_prompt` |  | string \| null | no |  | ≤ 1024 characters | Cur síos ar na gnéithe ba cheart a eisiamh ón tsamhail ghinte. |
| `face_limit` |  | integer \| null | no |  | 1,000 – 2,000,000 | Sprioc shonrach líon aghaidheanna le haghaidh giniúint mogalra, a sháraíonn roghnú oiriúnaitheach líon na samhla nuair a chuirtear ar fáil é. |
| `texture` |  | boolean | no | `true` |  | Rialaíonn sé an bhfaigheann an tsamhail uigeachtaí ginte. |
| `pbr` |  | boolean | no | `true` |  | Cumasaigh ábhair PBR (Rindreáil Fhisiciúil Bhunaithe), rud a chuireann giniúint uigeachta ar siúl freisin nuair atá sé true. |
| `model_seed` |  | integer \| null | no |  |  | Síol a úsáidtear chun giniúint na céimseata a dhéanamh in-atáirgthe. |

| `auto_size` |  | boolean | no | `false` |  | Scálú uathoibríoch chun toisí réadúla an tsampla a thabhairt i méadair. |
| `quad` |  | boolean | no | `false` |  | Roghnaigh idir aghaidheanna triantánacha agus ceathairshleasáin le 4 thaobh trí thopolaíocht quad a chumasú. Maidir le torthaí quad, seoltar comhad FBX ar ais gach uair a sholáthraíonn Tripo na sonraí mar bhearta FBX. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Is féidir an scagadh a mhaolú trí false a shocrú, ar choinníoll go bhfuil údarú ag an nglaoiteoir. |

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

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.
