# Topaz Upscale Image Generative API

> Aumentador generativo de imagens com vários modelos, aprimoramento facial e modo Redefine orientado por prompt

Aumenta uma imagem de 1x a 4x com uma escolha de `model`, incluindo Wonder 3.5, Wonder 3, Recover 3, Redefine e Recovery V2. O aprimoramento facial tem controles próprios de intensidade e criatividade. Redefine adiciona um `prompt` de até 1024 caracteres, além de `creativity`, `texture`, `sharpen` e `denoise`. Adequado para fontes pequenas ou borradas.

- 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.com/v1/run/topaz/upscale/image/generative`
- Quote: `POST https://api.doitong.com/v1/quote/topaz/upscale/image/generative`
- Docs page: https://doitong.com/pt-BR/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.com/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 da imagem de origem para aumento de resolução. |
| `model` |  | enum (string) | no | `Wonder 3` | `Wonder 3.5`, `Wonder 3`, `Wonder 2`, `Wonder`, `Recover 3`, `Standard MAX`, `Redefine`, `Recovery V2`, `Recovery` | Seleção do modelo generativo de aumento de resolução: Recovery e Recovery V2 reconstroem imagens de resolução extremamente baixa; Redefine usa prompts para orientar detalhes criativos; Standard MAX prioriza precisão e alta qualidade; Recover 3 reconstrói detalhes naturais. Na família Wonder, Wonder e Wonder 2 precedem Wonder 3, o modelo generativo de realismo mais avançado; o lançamento mais recente, Wonder 3.5, fornece detalhes mais refinados com menos repetição de padrões. |
| `upscale_factor` |  | number | no | `2` | 1 – 4 | Multiplicador de ampliação da imagem; por exemplo, 2.0 dobra ambas as dimensões. |
| `crop_to_fill` |  | boolean | no | `false` |  |  |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Formato usado para a imagem com resolução aumentada. |
| `subject_detection` |  | enum (string) | no | `All` | `All`, `Foreground`, `Background` | Controla como os objetos são detectados ao aprimorar imagens com Recovery V2, Wonder 3 ou Recovery. |
| `face_enhancement` |  | boolean | no | `true` |  | Ativação do aprimoramento de rosto na imagem. |
| `face_enhancement_creativity` |  | number | no | `0` | 0 – 1 | Controle de criatividade do aprimoramento de rosto, ativo somente quando o aprimoramento de rosto está habilitado: defina 1.0 para criatividade máxima ou 0.0 para nenhuma. |
| `face_enhancement_strength` |  | number | no | `0.8` | 0 – 1 | Controle da intensidade do aprimoramento de rosto, ativo somente quando o aprimoramento de rosto está habilitado: defina 1.0 para aprimoramento máximo ou 0.0 para nenhum. |
| `enhancement_strength` |  | enum (string) \| null | no |  | `low`, `medium`, `high` | Intensidade do aprimoramento generativo de resolução, configurada automaticamente quando não especificada; os modelos compatíveis são Wonder 3.5 e Wonder 3. |
| `creativity` |  | integer \| null | no |  | 1 – 6 | Criatividade do aumento generativo de resolução de 1 a 6, compatível apenas com Redefine. Aumentá-la adiciona detalhes mais imaginativos ou alucinados. |
| `texture` |  | integer \| null | no |  | 1 – 5 | Controle de detalhes de textura exclusivo do aumento generativo de resolução do Redefine, aceitando níveis de 1 a 5. |
| `prompt` |  | string \| null | no |  | ≤ 1024 characters | Texto de orientação para o aumento generativo de resolução, limitado a 1024 caracteres e compatível apenas com Redefine. |
| `autoprompt` |  | boolean \| null | no |  |  | Ativação da geração automática de prompt disponível exclusivamente no aumento generativo de resolução do Redefine. |
| `sharpen` |  | number \| null | no |  | 0 – 1 | Intensidade da nitidez de 0.0 a 1.0, compatível apenas com Redefine. |
| `denoise` |  | number \| null | no |  | 0 – 1 | Intensidade da redução de ruído de 0.0 a 1.0, compatível apenas com Redefine. |
| `detail` |  | number \| null | no |  | 0 – 1 | Intensidade da recuperação de detalhes de 0.0 a 1.0, compatível apenas com Recovery V2. |
| `enable_safety_checker` |  | boolean | no | `true` |  | A filtragem pode ser relaxada definindo false, desde que o chamador esteja autorizado. |

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.com/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.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/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.com/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.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": "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.
