# Topaz Upscale Image Generative API

> Generatyvinis vaizdų didintuvas su daugybe modelių, veido patobulinimu ir užklausa valdomu Redefine režimu

Padidina vaizdą nuo 1x iki 4x, pasirinkdami `model`, įskaitant Wonder 3.5, Wonder 3, Recover 3, Redefine ir Recovery V2. Veido patobulinimas turi atskirus stiprumo ir kūrybiškumo slankiklius. Redefine prideda iki 1024 simbolių `prompt` bei `creativity`, `texture`, `sharpen` ir `denoise`. Tinka mažiems arba sulietiems šaltiniams.

- 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/lt/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 | Šaltinio vaizdo URL raiškai didinti. |
| `model` |  | enum (string) | no | `Wonder 3` | `Wonder 3.5`, `Wonder 3`, `Wonder 2`, `Wonder`, `Recover 3`, `Standard MAX`, `Redefine`, `Recovery V2`, `Recovery` | Generuojamo raiškos didinimo modelio pasirinkimas: Recovery ir Recovery V2 atkuria itin mažos raiškos vaizdus; Redefine naudoja raginį kūrybinėms detalėms valdyti; Standard MAX teikia pirmenybę tikslumui ir aukštai kokybei; Recover 3 atkuria natūralias detales. Wonder šeimoje Wonder ir Wonder 2 yra ankstesni už Wonder 3 – pažangiausią generuojamo realizmo modelį; naujausia versija Wonder 3.5 pateikia smulkesnes detales su mažesniu raštų pasikartojimu. |
| `upscale_factor` |  | number | no | `2` | 1 – 4 | Vaizdo didinimo daugiklis; pavyzdžiui, 2.0 padvigubina abu matmenis. |
| `crop_to_fill` |  | boolean | no | `false` |  |  |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Raišką padidinusio vaizdo formatas. |
| `subject_detection` |  | enum (string) | no | `All` | `All`, `Foreground`, `Background` | Nurodo, kaip aptinkami objektai gerinant vaizdus naudojant Recovery V2, Wonder 3 arba Recovery. |
| `face_enhancement` |  | boolean | no | `true` |  | Vaizdo veidų gerinimo įjungimas arba išjungimas. |
| `face_enhancement_creativity` |  | number | no | `0` | 0 – 1 | Veidų gerinimo kūrybiškumo valdiklis, aktyvus tik įjungus veidų gerinimą: nustatykite 1.0 maksimaliam kūrybiškumui arba 0.0, kad jo nebūtų. |
| `face_enhancement_strength` |  | number | no | `0.8` | 0 – 1 | Veidų gerinimo stiprumo valdiklis, aktyvus tik įjungus veidų gerinimą: nustatykite 1.0 maksimaliam gerinimui arba 0.0, kad jo nebūtų. |
| `enhancement_strength` |  | enum (string) \| null | no |  | `low`, `medium`, `high` | Generuojamo raiškos didinimo gerinimo stiprumas, automatiškai sukonfigūruojamas, jei nenurodytas; palaikomi modeliai – Wonder 3.5 ir Wonder 3. |
| `creativity` |  | integer \| null | no |  | 1 – 6 | Generuojamo raiškos didinimo kūrybiškumas nuo 1 iki 6, palaikomas tik Redefine. Didinant jį pridedama daugiau vaizduotės ar haliucinuotų detalių. |
| `texture` |  | integer \| null | no |  | 1 – 5 | Tik Redefine generuojamam raiškos didinimui skirtas tekstūros detalių valdiklis, priimantis lygius nuo 1 iki 5. |

| `denoise` |  | number \| null | no |  | 0 – 1 | Triukšmo šalinimo intensyvumas nuo 0.0 iki 1.0, palaikomas tik Redefine. |
| `detail` |  | number \| null | no |  | 0 – 1 | Detalių atkūrimo intensyvumas nuo 0.0 iki 1.0, palaikomas tik Recovery V2. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Patikrą galima sušvelninti nustačius false, jei skambinantysis turi teisę tai daryti. |

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:

## 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({

  }),
});
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.
