# Z-Image Turbo Seamless Tiling API

> Modelo rápido de texto a imagen que produce salidas teselables, con teselado horizontal, vertical o bidireccional e inpainting

Genera imágenes que se repiten en los bordes, controladas por `tiling_mode` (both, horizontal o vertical), `tile_size` y `tile_stride`. Ejecuta hasta 8 pasos de inferencia y devuelve de 1 a 4 imágenes en png, jpeg o webp. Proporcionar `image_url` habilita imagen a imagen, y añadir `mask_image_url` habilita inpainting. `strength` establece cuánto cambia la entrada.

- Model id: `z-image/turbo/tiling`

- Price per megapixel of your output image: $0.02 / megapixel of output image (cheapest run $0.02 (20 API credits))
- Run: `POST https://api.doitong.com/v1/run/z-image/turbo/tiling`
- Quote: `POST https://api.doitong.com/v1/quote/z-image/turbo/tiling`
- Docs page: https://doitong.com/es/developers/models/z-image/turbo/tiling

## Pricing

Price: **$0.02 / megapixel of output image**. Price per megapixel of your output image: 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 $0.02 = 20 API credits (1 MP output image × $0.02).

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/z-image/turbo/tiling` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Prompt que orienta la generación de imágenes. |
| `image_size` |  | object {width, height} \| enum (string) | no | `square_hd` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9`, `auto` | Dimensiones de la imagen generada; 'auto' selecciona 1024x1024, a menos que se proporcione una imagen de entrada, en cuyo caso se utilizan sus dimensiones. |
| `num_inference_steps` |  | integer | no | `8` | 1 – 8 | Cantidad de pasos de inferencia que se ejecutarán. |
| `seed` |  | integer \| null | no |  |  | Seed para obtener imágenes reproducibles: un prompt y una seed idénticos producen una imagen idéntica cuando la versión del modelo no cambia. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Cantidad de imágenes solicitada para la generación. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Comprobación de seguridad que devuelve imágenes negras en lugar de las imágenes marcadas como no seguras. Un valor true activa la comprobación; false la desactiva solo para cuentas autorizadas, mientras que las solicitudes sin autorización se comprueban siempre. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Formato de archivo de la imagen resultante. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular`, `high` | Nivel de aceleración aplicado al procesamiento. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Controla si la expansión del prompt está habilitada. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | URL de la imagen utilizada para la generación de imagen a imagen o el relleno. Proporcionar mask_image_url selecciona el relleno; omitirlo selecciona la generación de imagen a imagen. |
| `mask_image_url` |  | string (image URL) \| null | no |  |  | URL de la máscara de inpainting proporcionada junto con la image_url obligatoria. La máscara conserva sin cambios las áreas negras y regenera las áreas blancas. |
| `strength` |  | number | no | `0.6` | ≤ 1, > 0 | Intensidad de transformación aplicada únicamente a una imagen proporcionada mediante image_url; de lo contrario, no se utiliza. |
| `tile_size` |  | integer | no | `128` | 32 – 256 | Tamaño de mosaico en el espacio latente, donde 64 corresponde a 512px, 128 a 1024px y 256 a 2048px. Las dimensiones de la imagen generada limitan automáticamente el tamaño en los ejes segmentados; la creación de parches requiere un valor par divisible entre 2. |
| `tile_stride` |  | integer | no | `64` | 16 – 128 | Paso del mosaico en el espacio latente, con equivalentes en píxeles de 32 = 256px, 64 = 512px y 128 = 1024px. Solo son válidos los múltiplos de 2; cualquier valor superior a la mitad del tamaño efectivo del mosaico se reduce automáticamente a ese límite. |
| `tiling_mode` |  | enum (string) | no | `both` | `both`, `horizontal`, `vertical` | Dirección del mosaico: 'both' cubre todas las direcciones, 'horizontal' cubre solo de izquierda a derecha y 'vertical' cubre solo de arriba abajo. |

File parameters (`image`, `mask_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/z-image/turbo/tiling?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/z-image/turbo/tiling?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.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/z-image/turbo/tiling", 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": "z-image/turbo/tiling",
      "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.
