# Tripo H3.1 Image to 3D API

> Generování 3D z jednoho obrázku s materiály PBR, quad sítěmi a nastavením počtu ploch

Vytváří 3D model z jednoho obrázku v `image_url`. Možnosti zahrnují `face_limit` (1,000 až 2,000,000), `texture`, `pbr`, standardní nebo detailní `texture_quality` a `geometry_quality`, topologii `quad`, `auto_size` a `orientation`. Výsledek obsahuje náhledový renderování a ID úlohy pro pozdější rigging.

- 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/cs/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 vstupního obrázku použitého k vytvoření 3D modelu. |
| `face_limit` |  | integer \| null | no |  | 1,000 – 2,000,000 | Explicitní cílový počet ploch pro generování sítě, který při zadání přepisuje adaptivní výběr počtu modelem. |
| `texture` |  | boolean | no | `true` |  | Určuje, zda model obdrží vygenerované textury. |
| `pbr` |  | boolean | no | `true` |  | Povoluje materiály PBR (Physically Based Rendering) a při hodnotě true také zapíná generování textur. |
| `model_seed` |  | integer \| null | no |  |  | Seed používaný k reprodukovatelnému generování geometrie. |
| `texture_seed` |  | integer \| null | no |  |  | Seed používaný k reprodukovatelnému generování textur. |
| `texture_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | Nastavení kvality textury; volba 'detailed' zvýší rozlišení textury. |
| `geometry_quality` |  | enum (string) | no | `standard` | `standard`, `detailed` | Nastavení kvality geometrie. |
| `texture_alignment` |  | enum (string) | no | `original_image` | `original_image`, `geometry` | Reference zarovnání textur: použijte 'geometry' pro vygenerovanou geometrii nebo 'original_image' pro vstupní obrázek. |
| `auto_size` |  | boolean | no | `false` |  | Automatické měřítko, které modelu přiřadí skutečné rozměry měřené v metrech. |
| `orientation` |  | enum (string) | no | `default` | `default`, `align_image` | Orientace modelu; 'align_image' jej automaticky otočí podle vstupního obrázku. |
| `quad` |  | boolean | no | `false` |  | Volba mezi trojúhelníkovými stěnami a čtyřstrannými quady povolením quad topologie. U výsledků s quady se vrací soubor FBX, kdykoli Tripo dodá data jako bajty FBX. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Kontrolu lze uvolnit nastavením na false, pokud je volající autorizován. |

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.
