# Topaz Upscale Image Generative API

> Mise à l’échelle générative d’images avec de nombreux modèles, amélioration des visages et mode Redefine guidé par prompt

Agrandit une image de 1x à 4x avec un choix de `model`, dont Wonder 3.5, Wonder 3, Recover 3, Redefine et Recovery V2. L’amélioration du visage possède ses propres réglages d’intensité et de créativité. Redefine ajoute un `prompt` de 1024 caractères maximum ainsi que `creativity`, `texture`, `sharpen` et `denoise`. Convient aux sources petites ou floues.

- Model id: `topaz/upscale/image/generative`
- Made by: Topaz Labs
- Category: Upscale
- Output: image
- Price per megapixel of your output image: from $0.01 / megapixel of output image (cheapest run $0.01 (10 API credits))
- Run: `POST https://api.doitong.ru/v1/run/topaz/upscale/image/generative`
- Quote: `POST https://api.doitong.ru/v1/quote/topaz/upscale/image/generative`
- Docs page: https://doitong.com/fr/developers/models/topaz/upscale/image/generative

## Pricing

Price: **from $0.01 / megapixel of output image** (the lowest tier; the quote prices your exact input). 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 $0.08 = 80 API credits (8 MP output image × $0.01).

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/topaz/upscale/image/generative` 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 |  | ≥ 1 characters | URL de l’image source pour la mise à l’échelle. |

Dans la famille Wonder, Wonder et Wonder 2 précèdent Wonder 3, le modèle génératif de réalisme le plus avancé ; la version la plus récente, Wonder 3.5, offre des détails plus fins avec moins de répétitions de motifs. |
| `upscale_factor` |  | number | no | `2` | 1 – 4 | Multiplicateur d’agrandissement de l’image ; par exemple, 2.0 double les deux dimensions. |
| `crop_to_fill` |  | boolean | no | `false` |  |  |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Format utilisé pour l’image mise à l’échelle. |
| `subject_detection` |  | enum (string) | no | `All` | `All`, `Foreground`, `Background` | Contrôle la détection des sujets lors de l’amélioration des images avec Recovery V2, Wonder 3 ou Recovery. |
| `face_enhancement` |  | boolean | no | `true` |  | Activation de l’amélioration des visages pour l’image. |
| `face_enhancement_creativity` |  | number | no | `0` | 0 – 1 | Contrôle de créativité de l’amélioration des visages, actif uniquement lorsque celle-ci est activée : définissez 1.0 pour une créativité maximale ou 0.0 pour aucune créativité. |
| `face_enhancement_strength` |  | number | no | `0.8` | 0 – 1 | Contrôle de l’intensité de l’amélioration des visages, actif uniquement lorsque celle-ci est activée : définissez 1.0 pour une amélioration maximale ou 0.0 pour aucune amélioration. |
| `enhancement_strength` |  | enum (string) \| null | no |  | `low`, `medium`, `high` | Intensité de l’amélioration par mise à l’échelle générative, configurée automatiquement si elle n’est pas spécifiée ; modèles pris en charge : Wonder 3.5 et Wonder 3. |
| `creativity` |  | integer \| null | no |  | 1 – 6 | Créativité de la mise à l’échelle générative, de 1 à 6, prise en charge uniquement par Redefine. Une valeur plus élevée ajoute des détails plus imaginatifs ou halluciné. |
| `texture` |  | integer \| null | no |  | 1 – 5 | Contrôle des détails de texture, exclusif à la mise à l’échelle générative de Redefine, avec des niveaux de 1 à 5. |
| `prompt` |  | string \| null | no |  | ≤ 1024 characters | Texte de guidage pour la mise à l’échelle générative, limité à 1024 caractères et pris en charge uniquement par Redefine. |

| `enable_safety_checker` |  | boolean | no | `true` |  | Le filtrage peut être assoupli en définissant false, si l'appelant est autorisé. |

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/topaz/upscale/image/generative?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/topaz/upscale/image/generative?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/topaz/upscale/image/generative", 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": "topaz/upscale/image/generative",
      "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.
